Is The Metabolism Of Testosterone To 5α-Dihydrotestosterone Required For Androgen Action In The Skin?

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.

Topical androgen receptor antagonists may not be necessary if 5-AR inhibitors like finasteride or dutasteride effectively reduce DHT levels. Combining a 5-AR inhibitor with a topical androgen antagonist could potentially enhance treatment, but oral use of androgen antagonists is too risky due to severe side effects.

The "DHT itch" is real and likely due to inflammation at the hair follicle, exacerbated by increased testosterone or androgens. Treatments mentioned include dutasteride, minoxidil, finasteride, and various topical solutions.

DHT is essential for androgenetic alopecia, not testosterone. Treatments like finasteride and dutasteride reduce DHT, halting hair loss.

The conversation discusses the mechanism of action of alfatradiol (17 alpha estradiol) in treating hair loss. It explores theories that it either inhibits 5 alpha reductase to prevent T->DHT conversion or aromatizes scalp T into 17-alpha-estradiol to save hair.

The conversation discusses the effects of using Tongkat ali and dioscorea to raise DHT levels, leading to increased body hair growth and an itchy scalp, without causing hair loss. The discussion also debates the role of DHT in male characteristics and its impact on sexual function, with differing opinions on its importance and effects.
