“Hair Pluck” Technique
Employs specialized forceps to “pluck” hair shafts from the scalp in order to determine the ratio of anagen (active/growth), to catagen (rest) and telogen (passive/falling) phases of the hair growth cycle
Hair Diameter Measurements
Direct hair diameter measurements are made using optical micrometric techniques.
Regimented Combing
This test employs a standardized combing technique designed to capture hair fallout collectively, which is then separated and counted to establish the number of individual broken, intact and bulbous hairs.
Trichological Count
Hair Count Analysis – allows the determination of the hair growth patterns, before and after treatment programs. A quantity of hair uniquely identified in a specific area of the scalp is used to establish product efficacy via video microscopic procedures.
