Alopecia Areata: A Comprehensive Review of Pathogenesis, Diagnosis, and Emerging Therapeutics

Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.

The user is experiencing diffuse thinning and inflammation despite using 2.5mg dutasteride daily, ciclopirox, and ketoconazole shampoos.
