Induction of T Cell Exhaustion by JAK1/3 Inhibition in the Treatment of Alopecia Areata

A 23-year-old male is experiencing diffuse hair loss and miniaturization, possibly due to high IGE levels after using tofacitinib. He seeks advice and has not yet consulted a dermatologist.

An arthritis drug restored significant hair in people with alopecia areata, but it is not effective for male pattern baldness. The drug, Upadacitinib, has serious side effects and is expensive.

An arthritis drug, baricitinib, is discussed as a potential treatment for autoimmune alopecia, not androgenetic alopecia. Ritlecitinib is also mentioned as a possible treatment for scarring alopecia.

The user is experiencing diffuse thinning and inflammation despite using 2.5mg dutasteride daily, ciclopirox, and ketoconazole shampoos. They are considering treatments like hydroxychloroquine and JAK inhibitors due to suspected scarring alopecia and have faced challenges in obtaining a scalp biopsy.

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.

Ritlecitinib and PP405 show promise for hair regrowth. Diagnosing the cause of hair loss is crucial before treatment.
