Bestimmung der rückfettungskinetik der haare

The sensitivity of the ground glass method for measurement of lipids can be considerably increased by a more sensitive polish of the glass plates. Therefore lipid measurements are possible in areas with only few sebaceous glands and even on scalp hairs. The hair lipids are continuously measureable without disturbance by sebum from the skin of the head and without extracting the hair of the test person; the time needed for measurement is only short The curve for the refatting of the hair can be quantitatively recorded. Beside the measurement of the dynamics of hair fatting, we now have a method to prove the cosmetical treatment of hair which also allows experiments to be carried out on a larger scale.
