The normal trichogram of pubic hair

Area of Science:

• Dermatology
• Trichology

Background:

• The trichogram analyzes hair cycle parameters.
• Understanding pubic hair characteristics is important for clinical and forensic applications.

Purpose of the Study:

• To investigate the parameters of the pubic hair trichogram.
• To assess age-related changes in pubic hair.
• To evaluate the impact of pregnancy and postpartum states on pubic hair.

Main Methods:

• A previously described trichogram technique was employed.
• Measurements were conducted on males and females across different life stages (non-pregnant, pregnant, postpartum).

Main Results:

• Pubic hair density and growth rate decrease with age in males and non-pregnant females.
• Females exhibited a higher percentage of telogen hairs.
• Hair thickness remained unchanged across all groups.
• Pregnancy and postpartum states showed no significant effect on pubic hair trichogram parameters.

Conclusions:

• Pubic hair exhibits distinct characteristics compared to scalp and axillary hair.
• The pubic hair cycle appears unaffected by pregnancy and postpartum conditions.
