Medical Treatment of Non-Scarring Alopecia

Minoxidil may inhibit androgen receptors and affect hormonal pathways, potentially explaining its effectiveness in treating androgenetic alopecia (AGA). Users discuss its varying effectiveness on scalp versus facial hair and note fewer side effects with topical use compared to oral.

The user experienced chronic telogen effluvium and mild male pattern baldness, treated with finasteride, oral minoxidil, and later switched to dutasteride, which stopped excessive hair shedding. Other treatments like low-level laser therapy, hair loss shampoos (except ketoconazole), and supplements were ineffective.

A 21-year-old male experiencing hair loss again despite using topical minoxidil (5%) for a year, possibly due to stress-related telogen effluvium. He is advised to continue using minoxidil and consider stress-reduction strategies while consulting a doctor for further evaluation.

Minoxidil and finasteride are more effective for diffuse thinning and crown balding because these areas have miniaturizing but still alive hairs that respond well to treatment. The hairline is less responsive to these medications due to its androgen sensitivity and often requires a transplant for restoration.

Topical tacrolimus is being considered for androgenetic alopecia, though its effectiveness is unproven. Other treatments mentioned include minoxidil, dutasteride, cyclosporine, and teicoplanin, with discussions on blocking the prolactin receptor for hair growth.

Hair loss from headspin friction might be improved with minoxidil if follicles are healthy. Finasteride isn't needed, and microneedling is suggested.
