Colocalization of Vitiligo and Alopecia Areata

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.

Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.

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.

A 35-year-old with alopecia areata has tried finasteride, topical and oral minoxidil, and dutasteride without success in stopping hair loss. The dermatologist suggests JAK inhibitors, but they are too costly, leading to uncertainty about the cause of hair loss.

The user is experiencing hair loss with possible causes including chronic telogen effluvium, diffuse alopecia areata, and androgenic alopecia. They have tried treatments like Nizoral shampoo, minoxidil, and finasteride, and are considering a biopsy for further clarity.

A user with alopecia totalis, borderline universalis, seeks advice on getting into a Xeljanz trial or appealing insurance for coverage. They experienced significant hair regrowth but are now seeing hair loss again and want to try Xeljanz.
