Background Objectives Methods Results Conclusions The validity of the self‐report questionnaire for hand eczema (HE) among Croatian hairdressers was not investigated previously, leading to uncertainty in the prevalence estimated from self‐reported data.To (1) investigate the validity of the self‐report questionnaire for HE in hairdressing apprentices and (2) examine the differences between apprentices who recognised their HE symptoms and those who did not.Clinical examination for HE signs on hands and wrists was performed by the Osnabrueck Hand Eczema Severity Index for 408 apprentices at four visits covering the entire schooling period. Self‐report HE was based on the Nordic Occupational Skin Questionnaire.Low sensitivity (7%–37%) with high specificity (≥95%) was observed, with both measures improving from baseline to last visit. The severity of HE signs was the only factor associated with the correct identification of HE signs in analyses adjusted for previous HE signs, health‐related quality of life, and atopic dermatitis (adjusted odds ratios of 1.58 with 95% confidence interval [1.06–2.35] and 1.74[1.38–2.19] at second and third follow‐up visit, respectively).Self‐report questionnaire for HE showed low sensitivity in hairdressing apprentices, especially at the beginning of training and in those with mild symptoms. Further validation studies following questionnaire modifications aimed at adolescent population are advised. [ABSTRACT FROM AUTHOR]

Hair disorders, including central centrifugal cicatricial alopecia (CCCA), traction alopecia (TA), and acquired trichorrhexis nodosa (ATN), commonly occur in individuals with curly textured hair. Curly textured hair in individuals of African descent has unique properties and can present diagnostic and therapeutic challenges. CCCA has been linked to uterine leiomyoma and type 2 diabetes mellitus, as well as fibroproliferation. TA often presents with a fringe sign and can arise from high‐tension hairstyles presumed to be protective. Trichoscopy is useful in establishing a diagnosis; perifollicular halos are more commonly seen than perifollicular erythema or scale in CCCA. In TA, miniaturized follicles, hair casts, and "flambeau sign" can be seen. Hairstyling practices likely contribute to TA and ATN; however, the data are mixed on the role of chemical relaxers and heat styling in CCCA. Unique considerations in the presentation of frontal fibrosing alopecia in curly textured hair have also been published recently. This review provides a comprehensive, up‐to‐date summary of these disorders with an emphasis on their unique properties, as well as considerations in hair care for curly textured hair.

ObjectiveMethodResultsConclusions\nKey PointsUntil recently, empirical studies had been limited with respect to investigating factors that influence the onset and maintenance of hair pulling disorder (HPD), particularly regarding the role of dysfunctional cognitions and beliefs. The primary aim of this study was to examine the relationships between symptom severity and belief domains in a sample with hair pulling disorder compared with non-clinical participants, using the Beliefs in Trichotillomania Scale (BiTS); a recently developed measure of relevant negative self-beliefs, coping efficacy beliefs, and perfectionist cognitions.Twenty adults with HPD and 43 age- and gender-matched control participants completed the BiTS and several measures of related constructs.HPD severity was significantly and positively correlated with negative self-beliefs and low coping efficacy, but not perfectionism, even after controlling for anxiety and depressive symptoms. Focussed hair pulling, but not automatic hair pulling, was correlated with each BiTS domain; however, once anxiety and depressive symptoms were controlled for, the significant relationship between focussed hair pulling and perfectionism was no longer apparent. The BiTS psychometric properties demonstrated good internal consistency and differentiated clinical from non-clinical participants, with clinical participants endorsing greater negative self-beliefs, lower coping efficacy, and greater perfectionism compared with control participants.Negative self beliefs, low coping efficacy, and perfectionism have differential relationships with HPD severity and hair pulling styles, variable on the presence of co-occurring anxiety and depressive symptoms. While further support for the BiTS internal consistency was obtained, future examination of divergent validity with a more diverse range of constructs is required.What is already known about this topic: Current cognitive-behavioural interventions for hair pulling disorder are designed to facilitate behaviour change by targeting the habit-formation and emotion-regulation mechanisms that maintain hair pulling behaviours.The Beliefs in Trichotillomania Scale (BiTS) measures three belief domains found to be relevant to hair pulling disorder: negative self beliefs, low coping efficacy, and perfectionism.Some cognitive-behavioural interventions additionally target cognitions and beliefs, however, few studies have investigated the relationships between relevant belief domains and hair pulling disorder severity and styles.Current cognitive-behavioural interventions for hair pulling disorder are designed to facilitate behaviour change by targeting the habit-formation and emotion-regulation mechanisms that maintain hair pulling behaviours.The Beliefs in Trichotillomania Scale (BiTS) measures three belief domains found to be relevant to hair pulling disorder: negative self beliefs, low coping efficacy, and perfectionism.Some cognitive-behavioural interventions additionally target cognitions and beliefs, however, few studies have investigated the relationships between relevant belief domains and hair pulling disorder severity and styles.What this topic adds: Independent of co-occurring anxiety and depressive symptoms, negative self beliefs and low coping efficacy, but not perfectionism, were associated with hair pulling severity.Negative self beliefs, doubts about one’s coping efficacy, and perfectionism were all associated with focussed hair pulling behaviours, but not automatic hair pulling behaviours. However, perfectionism was no longer correlated with focussed hair pulling upon controlling for anxiety and depressive symptoms.Assessment for these domains of dysfunctional beliefs, as part of formulation-driven cognitive-behavioural interventions for hair pulling disorder, is appropriate.Independent of co-occurring anxiety and depressive symptoms, negative self beliefs and low coping efficacy, but not perfectionism, were associated with hair pulling severity.Negative self beliefs, doubts about one’s coping efficacy, and perfectionism were all associated with focussed hair pulling behaviours, but not automatic hair pulling behaviours.

Since the evolution of technology, it created a growing importance in the education sector. The use of video graphics or multimedia tools becomes a useful instrument in learning and teaching in the education industry. This study determined the correlation between the utilization of video graphics in teaching Hairdressing and the students' performance. A descriptive method of research was applied to accomplish this study. A total of thirty-three (33) Grade Eleven TVL students served as the respondents of this study. The researcher used a survey questionnaire in checklist format as the main research instrument to gather needed data. Statistics tools such as mean, standard deviation mean scores, and frequencies were used. The significance was tested at the 0.05 probability level. Based on the data collected, the perception of the students to the utilization of video graphics in teaching Hairdressing has an overall interpretation of "highly observed". It was revealed that there is a significant difference between the pre and post-test exams, considering the delivery of the lesson, teacher's mastery, efficiency, and feedback. The results indicate no significant relationship except for efficiency and performing hair treatment, audio, and post-service activities. The results also showed a positive learning development in terms of lesson adaptation through pre- and post-test scores and performance scores based on what the students knew before and after exposure to the video graphics.

Natural hair curvature and colour are genetically determined human traits, that we intentionally change by applying thermal and chemical treatments to the fibre. Presently, those cosmetic methodologies act externally and their recurrent use is quite detrimental to hair fibre quality and even to our health. This work represents a disruptive concept to modify natural hair colour and curvature. We aim to model the fibre phenotype as it is actively produced in the follicle through the topical delivery of specific bioactive molecules to the scalp. Transcriptome differences between curly and straight hairs were identified by microarray. In scalp samples, the most variable transcripts were mapped by in situ hybridization. Then, by using appropriate cellular models, we screened a chemical library of 1200 generic drugs, searching for molecules that could lead to changes in either fibre colour or curvature. A pilot-scale, single-centre, investigator-initiated, prospective, blind, bilateral (split-scalp) placebo-controlled clinical study with the intervention of cosmetics was conducted to obtain a proof of concept (RNEC n.92938). We found 85 genes transcribed significantly different between curly and straight hair, not previously associated with this human trait. Next, we mapped some of the most variable genes to the inner root sheath of follicles, reinforcing the role of this cell layer in fibre shape moulding. From the drug library screening, we selected 3 and 4 hits as modulators of melanin synthesis and gene transcription, respectively, to be further tested in 33 volunteers. The intentional specific hair change occurred: 8 of 14 volunteers exhibited colour changes, and 16 of 19 volunteers presented curvature modifications, by the end of the study. The promising results obtained are the first step towards future cosmetics, complementary or alternative to current methodologies, taking hair styling to a new level: changing hair from the inside out.

Hair dyeing is widely performed around the world. Chemical and thermal burns can result from the components present in brightening and coloring products, as well as the application process. We present a case of a chemical burn after applying hair dye and review the literature on similar cases, the composition of hair dyes, their mechanism of action, and the process of burns. The patient was a 17-year-old girl, who presented to the Dermatology Clinic with a 13 × 10 cm ulcer on the scalp after hair dyeing in a hairdressing salon. General and local treatment was applied, with particular emphasis on specialized dressings. The ulcer site was replaced by an area of scarring after 11 months of treatment. Based on the presented case and the review of the literature, we conclude that hair dye treatments warrant careful attention for potential scalp complications. The diagnostic and therapeutic approach demands a multidisciplinary effort, with ongoing patient–doctor cooperation throughout the treatment, which may complicate and span several months.

This paper demonstrates the regulation of women's pregnant bodies through and by discourses of care. It illustrates how present practices reflect those of slavery where the dressing of the body, styling of the hair, and dancing, communicated gender difference that complicated sexual difference. 1 The presentation explores the body as material, fleshy, changing, and regulated. It demonstrates that even when motherhood is seen as a social construct, there is a sexual attachment to certain practices of mothering (such as pregnancy and breastfeeding) that speaks to its materiality which intersect with the ideological aspect of motherhood. Michel Foucault argues that the social actor is a mere body, and power is exercised upon individuals as bodies are categorized, trained in procedures, and placed in hierarchies. The body therefore becomes docile through its ability to learn, and to internalize discourses that regulate thoughts and behaviors. Using the narratives of ten CARICOM mothers residing in Barbados, this paper unpacks the body politic of motherhood, noting specifically how motherhood operates as institution.

During Australia's first nationwide lockdown due to COVID-19 in 2020, hairdressers and barbers were allowed to remain operating while beauty salons and similar businesses were ordered to shut. This article offers some preliminary insights into the impact of the pandemic on salon workers during the period, in particular the additional emotional labour required. Drawing on a survey of salon workers based in Australia (n = 92), this article considers the emotional labour involved in salon work in tandem with the impact of COVID-19 disruptions on this workforce. Results of the survey reveal the variety of emotional disclosures that salon workers generally encounter from clients and how these disclosures continued during the period, as well as the emotions experienced by workers themselves. Survey results suggest that many salon workers, who were themselves experiencing heightened levels of physical, emotional and financial vulnerability, were expected to continue their emotional roles for clients during a period of high anxiety and stress. This work suggests that future decision making ought to consider the impact on, and how best to support, all workforces who remain in operation during lockdowns, particularly emotional labourers, and not just those typically imagined as 'essential'.

Among the antiquities of the archaic period of Forest-Steppe Scythia, a group of elite burials of women, possibly endowed with priestly functions during their lifetime, stands out. Until recently, only two unrobbed burial complexes were known to contain the main burials of women of high social rank, in whose graves golden costume elements were found—primarily expressive details of headdresses. The barrows (kurgans) were discovered at the end of the 19th century when amateur excavations were actively carried out on the right bank of the Dnipro. As a result of research conducted by the author at the Skorobir necropolis (in the area of the Bilsk fortified settlement, on the left bank of the Dnipro), two similar graves were recently discovered, which provided new material that significantly expanded the known geographical distribution of this phenomenon. The materials are closely analogous to the previously discovered elite female burials of the Middle Dnipro (barrow 100 near the village of Syniavka, barrow 35 near the village of Bobrytsa) and allow us to highlight a number of stable elements of the funeral costume of noble women and the sets of objects that complemented them. In this article, we consider the social and cultural significance of female attire in elite burials and delimit the chronological framework of this previously understudied phenomenon within the first half of the 6th century BCE. The new finds offer unprecedented insight into the form and meaning of one type of female headdress which researchers have tried to reconstruct for over a century. [ABSTRACT FROM AUTHOR]

In several flowering plants, pollen is not delivered directly from the anthers to the pollinators but is transferred to and presented by another floral structure, a phenomenon known as secondary pollen presentation (2PP). The new pollen-presenting structure, that is, the pollen presenter, is usually the style, but other floral organs may also be involved in this within-flower pollen transfer. This transfer usually happens during late bud development when pollen is already released and thus is associated with extreme protandry. The evolutionary significance of 2PP is reflected by its occurrence in at least 29 families of angiosperms, suggesting many instances of independent evolution. The functional role of 2PP includes pollen saving and pollination accuracy, by reducing pollen loss and increasing the precision of pollen transfer to the stigma. Many types of 2PP have been described, distinguished either by the structure of the pollen-presenting organs or by the different processes involved in pollen transfer and presentation to pollinators. Herein three main mechanisms of 2PP are distinguished: (1) The deposition mechanism is the most common type of 2PP among angiosperms. Pollen is transferred to the presenter, often with the assistance of sticky secretions or hair tracts. (2) In the brush mechanism, pollen is wiped off of the anthers by attached hairs as the style elongates or moves relative to the anthers. (3) In the pump mechanism, the style acts as a piston, pushing the pollen out of a cylinder formed by laterally contiguous floral organs. In this article, we present a short introduction into the diversity and functional significance of 2PP, providing examples as case studies that can be easily observed in the lab or field courses. Potential avenues for future research on 2PP are also discussed. [ABSTRACT FROM AUTHOR]

The present article offers analysis of the garments of women represented in the burial chambers of the Thracian tombs at Kazanlak (280-265 BC) and Sveshtari (the end of the first/beginning of the second quarter of the 3rd c. BC). The accompanying accessories, makeup, hair dresses and shoes are also discussed. The women are dressed in a Greek fashion. Some of their garments have specific features and deliver complex, non-verbal messages, while manifesting a social status, identity, rank and personal qualities. Unquestionably, the depicted garments do not represent the usual, for that time in Thrace, clothing, but confirm the observations that the attire of the local elite follows completely the fashionable Hellenistic trends. The established diagnostic features of the garments point to the narratives of the discussed painted scenes: wedding motifs in Kazanlak tomb and a public event with religious and mythological connotations in Sveshtari.

This study attempts to investigate Jordanian oaths from a sociocultural and translational perspective. The study shows that Jordanian oaths are insufficiently explored from such a perspective. The paper uncovers that Jordanian oaths have many formulas and are taken in many social and cultural aspects such as religion, body parts, honor, headdress, curse, and Arabic coffee, among many other things. In order to conduct the study, examples resembling these different aspects of oaths are suggested, and some social and cultural details are given before the examples. To make the Jordanian oaths clear, each oath example is contextualized in a social and cultural setting and then followed by a literal translation. Finally, the examples are analyzed and discussed, translationally, socially, and culturally in order to give a ground evidence that Jordanian oaths are difficult to translate from Arabic into English.

This study explores vocational didactics and embodied knowledge in hairdressing education by studying how perceptive sensoriality is used by teachers and students in creating shared understandings of vocational knowledge. Among multiple actions, touch is distinguished as a central resource in learning the vocation, as it emerges in interaction between teacher and student related to the ongoing teaching and its assignment. The data is based on video-recordings displaying how touch is used in manipulating objects and material, or in assessing qualities and defects. In such instances, touch becomes a diagnostic criterion (Goodwin, 1997) to investigate how the material worked with can be evaluated and handled. To bridge the gap between individual and collective vocational knowledge, metaphors are of use. The results show two approaches to the teaching of perceptive sensoriality. In order to learn the vocational subject content the teaching need to provide for and practice the individual’s embodied sense of touch as well as the vocation’s verbalised collective feel. This is the core of the didactical challenge.

The study focuses on hair growth promotion skills for hair dressers and nutrition requirements for hair growth of females in Umunneochi local government area (LGA) of Abia State. Specifically, the study aimed to examine the practices that promote human hair growth, assess the importance of human hair growth, determine the effect of poor nutrition on hair and identify the skills of hairdressers to promote hair growth. The study adopted a descriptive research design. Population for the study was 2,800. Sample for the study was 200 using a multistage sampling techniques involving simple random sampling and purposive sampling techniques. The instrument for data collection was a questionnaire. Data collected were analyzed using mean. The result of the study examined six practices that promote human hair growth, six importance of human hair, eight effects of poor nutrition on hair and eleven hairdressers’ skills were identified. It was suggested that adolescents and mothers should be encouraged to eat recommended diets to suit their age; they should maintain a good hairdresser; and they should consult a dermatologist at regular intervals and follow their advice.

The representations of a Black woman character's hair say something about her. The hair of a Black character is never neutral and nuances of hair are noticed by Black woman audience members. In my research interviewing 103 Black women about the representations of Black women in the shows/films they consumed, 12% of the participants discussed the politics of Black women's hair as a marker of authentic representation. This article analyzes contemporary representations of hair in shows primarily directed/produced by Black women, arguing that representations of Black women's hair can be empowering to Black women audience members. Hair styles, rituals, and the bonding over hair in shows and films are important. Even if these on-screen hair moments seem fleeting and unimportant, they are significant in that they affirm and celebrate the beauty, the connection, the love between and among Black women and their experiences. This article weaves interview excerpts into an analysis of Black women characters in contemporary film/series, making the argument that when Black women are behind the camera, Black girl's/women's hair represents power and pride through natural/Afrocentric styles and these representations matter to the audience.

Background: It is known that a large number of hairdressing apprentices (HA) develop occupational contact dermatitis (OCD) during schooling, but studies that address prevalence of contact sensitization in HAs with hand eczema are missing. Objectives: To assess the prevalence, incidence rate and clinical characteristics of OCD, including contact sensitization, in a sample of Croatian HAs. Materials and Methods: A total of 408 HAs from 25 Croatian towns were examined at the beginning of education and monitored at the end of each school year. Clinical evaluation of skin changes was performed using the Osnabrueck Hand Eczema Severity Index (OHSI). Standard patch test (PT) with baseline and hairdresser series of contact allergens was performed in 46 HAs with skin changes lasting ≥3 months. Results: The overall incidence rate of OCD was 32.3/100 person‐years, and the 3‐year prevalence 50.3%. Contact sensitization was found in 14 out of 46 (30.3%) HAs, with 10 of these 14 HAs (71.4%) sensitized to specific hairdressing allergens. The strongest reactions were found to PPD. HAs with positive PT had higher OHSI than HAs with negative patch test (median, IQR: 3, 2–4 vs. 2, 2–4). Conclusions: Contact sensitization to specific hairdressing chemicals was found in 71.4% of HAs with a positive patch test, supporting evidence on the early contact sensitization to occupational allergens among HAs.

This study introduces a virtual reality (VR)-based remote hair design training system that addresses the limitations of physical presence. By leveraging virtual environments and eliminating the need for tangible tools, this system allows hairstylists and learners to collaborate and master hair-design techniques from a distance. In this approach, a section of a user's hair was derived from their photograph, and during the training, the most compatible 3D hair model was integrated with the user's 3D avatar using the recommended matching procedure. This aligned hairstyle was subsequently incorporated into a 3D model for hair simulation. Further, VR HMD interaction mapping was used for hair cutting and styling. A collaborative environment for hair design has been crafted, enabling multiple participants to partake in remote hairstyle education. This system offers cost-effective training, enhances cooperative learning, and aligns with the requirements of contact-free education. In essence, this research has transformed remote hair design training with immersive VR technology. To verify the system's accuracy, tests were conducted, and the results showcased enhancements in the matching procedure. [ABSTRACT FROM AUTHOR]

Neuro-navigation is a key technology to ensure the clinical efficacy of TMS. However, the neuro-navigation system based on positioning sensor is currently unable to be promoted and applied in clinical practice due to its time-consuming and high-cost. In the present study, we designed I-Helmet system to promote an individualized and clinically friendly neuro-navigation approach to TMS clinical application. I-Helmet system is based on C++ with a graphical user interface that allows users to design a 3D-printed helmet model for coil navigation. Besides, a dedicated coil positioning accuracy detection method was promoted based on three-dimensional (3D) printing and 3D laser scanning for evaluation. T1 images were collected from 24 subjects, and based on each image, phantom were created to simulate skin and hair. Six 3D-printed helmets with the head positioning hole enlarged by 0-5% tolerance in 1% increments were designed to evaluate the influences of skin, hair, and helmet-tolerance on the positioning accuracy and contact force of I-Helmet. Finally, I-Helmet system was evaluated by comparing its positioning accuracy with three skin hardnesses, three hair styles, three operators, and with or without landmarks. The accuracy of the proposed coil positioning accuracy detection method was about 0.30 mm in position and 0.22° in orientation. Skin and hair had significant influences on positioning accuracy (p < 0.0001), whereas different skin hardnesses, hair styles, and operators did not (p > 0.05). The tolerance of the helmet presented significant influences on positioning accuracy (p < 0.0001) and contact force (p < 0.0001). The positioning accuracy significantly increased (p < 0.0001) with landmark guided I-Helmet. 3D-printed helmet-type Neuro-navigation approach (I-Helmet) with 3% tolerance and landmarks met the positioning requirements for TMS in clinical practice with less than 5 N mean contact force, 3-5 mm positioning accuracy, 65.7 s mean operation time, and 50-yuan material cost. All the results suggest that the cost of I-Helmet system may be much less than the that of training clinical doctors to position the coil of TMS operation during short period of time.

We introduce CT2Hair, a fully automatic framework for creating high-fidelity 3D hair models that are suitable for use in downstream graphics applications. Our approach utilizes real-world hair wigs as input, and is able to reconstruct hair strands for a wide range of hair styles. Our method leverages computed tomography (CT) to create density volumes of the hair regions, allowing us to see through the hair unlike image-based approaches which are limited to reconstructing the visible surface. To address the noise and limited resolution of the input density volumes, we employ a coarse-to-fine approach. This process first recovers guide strands with estimated 3D orientation fields, and then populates dense strands through a novel neural interpolation of the guide strands. The generated strands are then refined to conform to the input density volumes. We demonstrate the robustness of our approach by presenting results on a wide variety of hair styles and conducting thorough evaluations on both real-world and synthetic datasets. Code and data for this paper are at github.com/facebookresearch/CT2Hair. [ABSTRACT FROM AUTHOR]
