Therapeutic Efficacy of Liquid Nitrogen Cryotherapy for Treatment of Alopecia Areata

The study evaluated liquid nitrogen cryotherapy for alopecia areata in 95 patients aged 16-70, with weekly treatments for 6 weeks and follow-ups at 3 and 6 months. Significant hair regrowth (over 50% reduction in SALT score) was observed in 27.4% of patients. No significant links were found between treatment success and age, gender, or disease duration. The study concluded that liquid nitrogen cryotherapy is a simple, convenient, and effective treatment for alopecia areata.
