The normal trichogram of pubic hair

The parameters of the trichogram of the pubic hair were studied with a previously described technique. Measurements were made on males and on non-pregnant, pregnant and post-partum females. In males and non-pregnant females denisty and rate of growth steadily decrease with age. There was a higher percentage of telogens in women. Hair thickness was not modified. The most important findings are related to pregnancy and post-partum which did not induce any change in the parameters of the trichogram of the public area. These findings indicate a behaviour of the pubic hair different from the scalp and axillary hair.
