The investigations were carried out on 509 individuals of both sexes whose ages ranged between 2 and 69 years. The subjects were grouped according to 5 age periods. The results of this study were as follows: 1. The mean value of the daily scalp hair growth rate was 0.401+ 0.037mm. 2. The daily hair growth rate of each groups were as follows: under 10 years of age; 0.367+0.032mm, in the teenagers; 0.419,+0. 032mm, in the twenties0.398+0.037mm, in the thirties and fourties; 0.394+0.034mm, above 50 years of age 0.386+029mm. 3.
