New hair growth device fits easily under a baseball cap

Engineers at the University of Wisconsin-Madison (USA) have developed a hair growth stimulator that generates electricity from the user's body movements. The gadget is so compact that it can fit under a baseball cap.

Treatment of baldness by the method of electrotrichogenesis (stimulation of weakened and "dormant" hair follicles using an electric field) is not innovative. Its main drawback is the presence of bulky devices and limited battery capacity.

So far, the effectiveness of the new device has only been tested in mice. The next step is to test its ability to interact with human cells. At the same time, the researchers clarify that the device they have created is intended, rather, for the prevention of baldness - that is, it will be effective at the earliest stage of hair loss. The technology, unfortunately, is not able to reproduce new hair follicles in the structure of the skin that has completely lost them.

The commercial prospects of the new device will only be possible in a few years, since the patented technology has yet to be tested on humans.
