Glossary Primary Hair Follicles

initial hair-producing structures formed during fetal development

Primary hair follicles are the initial hair-producing structures that develop in the skin during fetal development. These follicles typically give rise to thicker, coarser hairs, such as those found on the scalp, eyebrows, and eyelashes. They are distinct from secondary hair follicles, which produce finer, shorter hairs like those on the body and face.

community Does ketokonazole on its own improve androgenetic alopecia?

in Ketoconazole 10 upvotes 5 months ago

Ketoconazole can slightly improve hair density and is best used as an adjunct to treatments like finasteride and minoxidil. It helps with scalp health but won't stop androgenetic alopecia on its own.

Does a hair transplant increase hair density? A hair transplant can improve density, but results vary by individual factors.

learn Finasteride

Does hair strand thickness decrease in men with androgenic alopecia? Can finasteride help restore it? Androgenic alopecia thins hair strands by miniaturizing follicles. The pivotal finasteride trials (1,553 men, 1 mg/day, two years) report increased hair counts and improved assessed appearance, but they measured density, not the diameter of individual strands, so the effect on thickness itself is not established.
