The future of hair loss treatment might be a bit more shocking than expected. Recent research showcases an experimental electrical comb that seems especially effective at combating baldness—at least in mice.

Scientists at Beihang University in China developed the contraption, which they’ve dubbed “Detangle.” Shaved mice treated with the comb experienced substantially more hair regrowth than mice given existing medications like minoxidil, the active ingredient in Rogaine, they found. Though more study is needed, the researchers are hopeful their device can be a valuable treatment for androgenetic alopecia, the most common form of baldness.

“[T]hese results demonstrate that electrostimulation via the Detangle system promotes hair growth and follicle regeneration in a safe and effective manner,” they wrote in their paper, published this month in the journal Nature Communications.

Minoxidil is an effective treatment for androgenetic alopecia, but it has its drawbacks. Many users hate the messy topical gels or creams typically used for application, for instance. Pill-based versions of minoxidil are easier to take but may cause unwanted hair growth elsewhere. And importantly, some people simply fail to respond to the drug or only experience modest regrowth.

Another limitation of topical agents like minoxidil is that very little of the drug actually manages to push through the skin and reach the hair follicles where it’s needed. That’s one limitation the researchers are aiming to address with their Detangle system—a name inspired by the 2010 Disney film retelling of Rapunzel, Tangled.
