The use of a phototherapeutic laser to stimulate the activity of the hair follicle is not news. Interest in the other – the team of Professor Keon Jae Lee of the Korean Institute of Science and Advanced Technology among the first in the world developed an application technology for these principles. It is a low-power laser analog that significantly accelerates the growth of hair in mammals.
Instead of a powerful laser, the professor's team used weak microlide-diodes (μLED). They placed 900 such emitters on a panel the size of a postage stamp, flexible enough to withstand 10,000 cycles of twisting. The power of the system is less than one thousandth of a medical phototherapy laser, it practically does not heat the skin upon irradiation and has no side effects.
In experiments specially shaved mice were irradiated with red light once a day for 15 minutes for 20 days. In parallel, the same group took a proven drug for hair growth minoxidil, plus there was a control group with which they did not do anything. Irradiation showed an excellent effect, the hair grew much faster than in other groups, over a large area and had an average longer length than with natural growth.
While the technology is experimental and has not yet been used on a person, it is not difficult to imagine a cap with LEDs, which for a few sessions helps to restore lost hair. Plus, such therapy would help restore hair after chemotherapy or help those who are naturally born beardless.js.src = “&version=v2.8”; 'script', 'facebook-jssdk'));
