The hair growth of the scalp is influenced by many systemic and local factors. So the study of standard hair growth rate is very important for the diagnosis and treatment of some pathological conditions. That study has not been done well in Korea. The present study was to establish the standard hair growth rate of the scalp of healthy Koreans at different ages. 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.
