Did you mean Hair Follicle Density?

Glossary Hair Follicle Density

number of hair follicles per unit area of skin

Hair Follicle Density, also known as Follicular Density or Hair Density, refers to the number of hair follicles per unit area of the scalp or skin. It is typically measured in follicles per square centimeter. This metric is important for assessing hair health, diagnosing conditions like alopecia, and planning hair restoration treatments. Higher follicle density generally indicates thicker hair coverage, while lower density can be a sign of thinning hair or hair loss.

community Redensyl for Hair Loss — What It Can and Can’t Do

9 months ago

community why are beard gains on min usually permanent?

in Minoxidil 43 upvotes 1 year ago

Beard gains from minoxidil are usually permanent due to facial hair follicles' lower sensitivity to DHT. Scalp hair requires ongoing DHT suppression with treatments like finasteride, dutasteride, and RU58841 to maintain gains after stopping minoxidil.

learn Cetirizine

How does cetirizine reduce inflammation linked to hair loss? Cetirizine is proposed to lower prostaglandin D2 and raise prostaglandin E2 around hair follicles; three small trials of a compounded 1% topical report modest increases in hair density and shaft thickness, with minoxidil doing better head-to-head. Topical cetirizine is off-label and unapproved for hair loss, and the evidence is too thin to call it effective or safe.

learn Metformin

Does metformin help control DHT levels that trigger androgenic alopecia? Metformin has been shown to lower circulating androgens in women with PCOS, but no published study has measured scalp DHT, 5-alpha reductase activity in the follicle, or hair density in anyone taking it — so its effect on pattern hair loss is untested, and it is not a DHT blocker.
