research Comparative analysis of temperature‐controlled cryotherapy versus intralesional triamcinolone acetonide injection for alopecia areata: An intrasubject split‐lesion pilot study
In this pilot study, cryotherapy using a device that precisely controls cooling duration improved hair regrowth for patchy alopecia areata when applied for 20 seconds with two freeze-thaw cycles, similar to standard triamcinolone acetonide injections, but not when applied for 10 seconds.
