Key Points:

Researchers at Beihang University in China have developed an innovative comb called the Detangle that stimulates hair growth using electrodes and delivers medication directly to hair follicles.
In tests on mice, the Detangle achieved 100% hair regrowth over 28 days, outperforming minoxidil (70% regrowth) and finasteride.
The device works by lifting the scalp with specially designed teeth and applying tiny electrical pulses to enhance the penetration of therapeutic molecules into hair follicles.
The comb also promotes new blood vessel formation around hair follicles, improving blood flow and supporting hair growth.
While human trials have not yet begun, researchers believe the Detangle could be a promising treatment for androgenetic alopecia, addressing limitations of current FDA-approved options like minoxidil and finasteride.
