Abstract
A procedure for screening a candidate substance for biological hair care activity comprises (i) microdissecting and isolating at least one viable hair follicle and the epidermal surroundings thereof, while preserving the continuity of such at least one hair follicle and the epidermal environment thereof, but removing the adipose tissue therefrom, (ii) incubating the at least one hair follicle in a nutrient medium for a given period of time, (iii) contacting the at least one incubated hair follicle with the candidate substance for biological hair care activity, and (iv) measuring a marker of the hair care activity of the candidate substance and thence evaluating the results of such measurement in comparison with a control.
