The Efficacy of Combining 308 Nm-Excimer Light and Topical Steroid in the Treatment of Alopecia Areata

Alopecia Areata can have a large impact on patients' quality of life, causing both cosmetic and psychosocial distress. Studies on the impact of hair loss have shown high levels of self-consciousness, jealousy, embarrassment, depression, introversion, and decreased self-esteem .

Alopecia Areata can occur at any age, but it is most common among young and middle-aged people . Both sexes are equally affected. Several environmental factors have been suggested as triggering Alopecia Areata, including infection, drugs, trauma, and stress. Thyroid autoimmune disease, atopy, and vitiligo are commonly associated. Diverse physical or psychological insults may trigger the episodes of Alopecia Areata, but there is no evidence that they influence prognosis.

Etiology of Alopecia Areata is not completely understood, and the majority of evidence suggests that genetically predisposed individuals, when exposed to an unknown trigger, develop a predominantly autoimmune reaction, leading to acute hair loss.

Although many patients improve spontaneously or respond to standard therapy, treatment can be quite challenging in those with more severe and refractory disease .

Topical corticosteroids are often the first line of treatment for mild patchy alopecia, with the underlying mechanism being containment of inflammation and hastening of the recovery of damaged hair follicles . Additionally, corticosteroids may be delivered via intralesional injection with slightly better effects (63% with complete regrowth within 4 months in one study . However, this method cannot be used for rapidly progressing variants and does not prevent hair loss at other sites . Furthermore, both topical and intralesional steroids increase the risk of cutaneous atrophy at the site of treatment, and intralesional steroids may decrease bone mineral density .
