Scientists in China have developed a special device in the form of an electric comb designed to fight hair loss and stimulate growth.
The system, called Detangle, was presented in a study published in the scientific magazine Nature Communications. The device combines electrical stimuli with a mechanism that allows for sending therapeutic substances deep into the skin, close to hair buds.
According to researchers from Beihang University in Beijing, electrical impulses help activate the folics, while integrated technology enables deeper insight into molecules aimed at handling hair loss.
The results of testosterone – based hair – dropping mice were especially promising. After 28 days, animals that did not receive treatment regenerated only about one percent of their hair in the shaved area.
Meanwhile, in mice that were subjected only to electrical stimuli, the increase reached about 40 percent. Even better results were recorded when the device was combined with experimental substances aimed at stimulating blood vessels around folices and preventing hormonal mechanisms that cause their contraction.
The highest result was reached by animals who received full treatment, where electrical stimulus was combined with both experimental therapies. According to researchers, the regeneration of hair in this group reached about 97.85 percent.
However, this technology has been tested only on rats so far. Before it can be used in humans, further studies are needed to prove its security and effectiveness.
If the results are confirmed in future trials, electrical combs can open a new way to treat hair loss and baldness.
