Efficacy, Safety, and Tolerability of a Wearable Electrotrichogenic Device in Men with Androgenetic Alopecia: A Randomized, Double-Blind, Sham-Controlled Trial.

An intention-to-treat sensitivity analysis including all randomized participants with available measurements for month 6 (irrespective of adherence) showed an attenuated between-group difference in Δ6 total hair density that did not reach statistical significance (active − sham: 10.34 hairs/cm 2 ; 95% CI − 11.03 to 31.72; Welch’s p = 0.33; n = 47 in active ETG group, n = 29 in sham group).

Finally, this trial focused on men; adequately powered randomized trials in women remain an important next step, and preliminary internal observations suggest a positive trend, but controlled studies are required to confirm efficacy and optimize protocols across sex-specific hair-loss patterns.
