finasteride androgens male-pattern baldness dihydrotestosterone DHT testosterone T vertex scalp hair Propecia MPB

TLDR Finasteride lowers scalp and blood DHT levels, potentially treating male-pattern baldness.

This study examined the effect of finasteride on androgen levels in the scalp hair and plasma of male-pattern baldness (MPB) patients. The results showed that finasteride significantly decreased the levels of dihydrotestosterone (DHT) in both plasma and vertex scalp hair, while having no effect on testosterone (T) levels. The study suggests that finasteride may be an effective treatment for MPB by reducing the levels of DHT.

nkrata in Research 830 upvotes 1 year ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
