TLDR The hot-wire hair removal device is no better than shaving.
A clinical study compared the effectiveness of a hot-wire hair removal device (no!no!) to traditional razor shaving on 22 subjects over an 8-week period, with a 3-month follow-up. Results showed no significant difference between the two methods in terms of hair density, regrowth rate, hair thickness, or color. Shaving was slightly more effective during the treatment phase, but both methods were statistically indistinguishable in the follow-up phase. The study concluded that the hot-wire device did not offer any benefits over shaving.
