Allergic and Irritant Contact Dermatitis Compared in the Treatment of Alopecia Totalis and Universalis: A Comparison of the Value of Topical Diphencyprone and Tretinoin Gel

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.

Topical finasteride (P-3074) can inhibit scalp DHT by up to 70%, with some users experiencing systemic absorption similar to oral use. Users discuss varying application frequencies and concentrations, with some noticing side effects when overused.

A user shared a new hair loss treatment protocol including topical dutasteride, latanoprost, caffeine, minoxidil, tretinoin, and triamcinolone acetonide. Others discussed the effectiveness and availability of these treatments, with some suggesting simpler oral alternatives.

The conversation discusses the effectiveness of topical tretinoin as a monotherapy for hair loss, with users suggesting it may not be as effective as minoxidil or finasteride. The original poster is considering other options like a phenol peel and is concerned about the risks of derma rolling.

A 21-year-old male is using a topical treatment for hair loss, including Dutasteride, Minoxidil, Tretinoin, Ketoconazole, and Hydrocortisone, along with derma rolling. He reports no side effects from the treatment and seeks feedback on its effectiveness for hair regrowth.

The user stopped oral treatments due to side effects and switched to a regimen of topical minoxidil, tretinoin, azelaic acid, and dermaneedling, with recent addition of topical finasteride. They are questioning the long-term effectiveness of non-hormonal methods and considering hair transplantation.
