TLDR Higher androgen levels do not cause baldness in men.

In a 1992 study involving 110 healthy young men, researchers examined the link between sex hormone levels and hair and skin characteristics. They found no significant correlation between the level of terminal hair growth and absolute androgen levels. However, significant correlations were observed between the metabolic rate of dihydrotestosterone/testosterone and the ratio of free to total testosterone. Contrary to common beliefs, men with a predisposition to balding had lower absolute serum androgen concentrations and were not more masculine in terms of body measurements. Additionally, no relationship was found between acne and androgen levels. The study concluded that higher androgen levels are not associated with baldness in men, challenging the widely held view.

community Anyone else’s beard took a huge hit on finasteride or dutasteride? Would minoxidl hepl?

in Progress Pictures 105 upvotes 1 year ago

The effects of finasteride and dutasteride on beard growth, whether minoxidil would help with facial hair loss caused by DHT blockers, and anecdotal evidence from users who have experienced either decreased or increased facial hair density while using these treatments.

community Diffuse hair loss and scalp biopsies

in Research 692 upvotes 3 months 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.
