Case Report: Repigmentation and Complete Hair Regrowth in an 11-Year-Old Preadolescent with Alopecia Totalis Treated with a JAK Inhibitor

This case study reports a young male with alopecia universalis experienced significant hair whitening following baricitinib treatment, highlighting the need for further research on JAK inhibitors' impact on hair pigmentation and their underlying mechanisms.

This review explores the shared pathogenesis of alopecia areata and vitiligo and compares treatment responses, noting that hair regrowth in alopecia areata occurs more rapidly than skin re-pigmentation in vitiligo, possibly due to differences in stem cell biology and treatment effects on melanocytes.

This study highlighted the need for more extensive research, ideally randomized controlled trials with larger patient groups, to determine the effect of the indicated treatment on hair repigmentation following AA.

This review discusses the potential of JAK inhibitors as a promising treatment strategy for alopecia areata, highlighting their mechanism and recent FDA approval based on clinical trial efficacy.

Alopecia Areata is an autoimmune condition causing hair loss with no cure and treatments that often don't work well.

This case study reported that a 62-year-old woman with alopecia areata experienced significant hair regrowth with completely non-pigmented white hair following a 2-month course of oral prednisolone.

This case report describes persistent depigmented hair regrowth from an alopecia areata patch, challenging the previous assumption that such regrowth is only temporary.
