Alopecia Areata: Updates from the Mouse Perspective

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.

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 shared minimal results from using JXL-069 for hair loss, noting a slight lengthening of vellus hairs and plans to switch to a prodrug variant due to limited effectiveness. They also mentioned using finasteride and minoxidil, which have plateaued in results.

A user noticed a sudden bald spot and others suggested it might be alopecia areata, often stress-induced, recommending seeing a dermatologist for steroid injections. Topical minoxidil was mentioned as a successful treatment by one user.

PP405 is a safer alternative to JXL069 for hair loss treatment because it penetrates the skin effectively and degrades in the blood, avoiding systemic toxicity. JXL069, when forced into the body, can cause dangerous side effects like lactic acidosis due to its inability to degrade safely.

Lichen Planopilaris (LPP) is an autoimmune condition causing permanent hair loss and fibrosis, often misdiagnosed. Treatments include pioglitazone, topical corticosteroids, anti-inflammatory medication, and Jak inhibitors.
