Noha Nabil Doghaim, MD, from Tanta University in Egypt, and colleagues randomized 40 patients with alopecia areata and 40 patients with androgenetic alopecia to receive either carboxytherapy or placebo. Study participants were followed up with monthly for three months.

Specifically, there was a significant reduction in dystrophic hair, black dots, yellow dots, and tapered hair, plus significant emergence of regrowing hair. Patients with androgenetic alopecia showed significant clinical and dermoscopic improvement after carboxytherapy plus significant increases in hair density as measured by digital dermoscopy. During the follow-up period, there was regression of the results, but measures were still significantly better than before treatment.

“Carboxytherapy seems to be a promising therapeutic option for patchy alopecia areata and could be helpful as an adjuvant therapy of androgenetic alopecia but more than six sessions are required and adjuvants are recommended for maintenance of the results,” the authors write.
