Immunohistochemical Characterization of the Cellular Infiltrate in Severe Alopecia Areata Before and After Minoxidil Treatment

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

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.

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.

Minoxidil's effectiveness varies due to differences in sulfotransferase enzyme levels in the scalp, affecting people with conditions like ASD, liver disease, and androgenic alopecia. Treatments like topical tretinoin, microneedling, and using minoxidil sulfate instead of regular minoxidil can improve results for those with low enzyme levels.

Minoxidil was applied to a single miniaturized hair follicle over four months, resulting in less miniaturization but not yet terminal growth. The user used a 5% minoxidil solution, specifically the Regaine brand, and observed changes using a handheld WiFi microscope.

The user experienced scalp inflammation and rapid hair loss after using minoxidil, despite initial success. Suggestions included switching to minoxidil foam, using oils, trying aspirin, and considering RU58841 for inflammation and hair loss management.
