Canine Alopecia Secondary to Human Topical Hormone Replacement Therapy in Six Dogs

A 23-year-old is experiencing hair loss and is using a regimen including topical Minoxidil, finasteride, spironolactone, and Estradiol gel as part of hormone replacement therapy (HRT). They are hopeful for hair regrowth and are considering using a micro needler, with others suggesting that their current treatment could lead to significant improvement.

Topical estradiol may help with hair loss but can have systemic effects, like reduced testosterone production. Using estrogen blockers can have negative side effects, such as joint pain and reduced sex drive.

Progesterone, hydrocortisone butyrate, and estrone base are discussed as treatments for hair loss. Topical progesterone and dutasteride are suggested to potentially reverse androgenic alopecia.

Topical estrogen or estradiol for hair loss is being discussed for its effectiveness compared to finasteride. Users are sharing their experiences and opinions on its potential benefits.

A female experiencing hair loss while on testosterone replacement therapy is using oral Minoxidil, Spironolactone, and finasteride, but still losing hair. Suggestions include switching to dutasteride, using topical anti-androgens, and reducing Nizoral shampoo use to prevent scalp dryness.

The user has been using oral minoxidil and dutasteride for hair loss without success and is considering adding topical 17α-estradiol, Pyrilutamide, Clascoterone, or cetirizine. They have confirmed low serum DHT levels and are exploring additional treatments due to genetic sensitivity to DHT and prostaglandin D2.
