308-nm excimer laser therapy in alopeciaareata To the Editor: Alopecia areata (AA) is believed to bea T-cell autoimmune disorder, and 308-nm excimerlaser is able to induce T-cell apoptosis in vitro,suggesting that this laser might be effective intreating this disease. We have performed a compar-ative prospective intraindividual study to access theeffectiveness of the 308-nm excimer laser in thetreatment of AA.
Nine patients were included in the study. The laser used was a 308-nm excimer laser (Talos,Wavelight Germany). Each lesion was treated twice a weekfor a maximum of 24 sessions. Initial fluencies were Fig 1. A, Alopecia areata patches before treatment. B, 50 mJ/cm2 less than minimal erythema dose. Then fluencies were increased from 50 mJ/cm2 every twosessions. Each treated lesion had an opposite side comparisons between the results obtained from these untreated target lesion serving as a control.

The occurrence of hair re- growth only on the treated patches proves the efficiency of this therapy and excludes the possibility of spontaneous hair regrowth that should be always considered when evaluating AA treatments. None of these patients lost their hair over a follow-up period of Department of Dermatology, Hoˆpital de l’Archet 3 months. On the other hand, no hair regrowth was observed in patients with either alopecia areatauniversalis (AAU) or alopecia areata totalis (AAT).
Moreover, the small size of the hand piece (maximum Department of Dermatology, Archet-2 hospital 25-mm diameter) makes the treatment of the entire scalp long and tiresome. These results are in agree- ment with the prognosis factors usually observed inAA. Interestingly, only a few sessions were necessaryto obtain aesthetically correct results in AAP.
