It is common for all humans to shed hair on a daily basis, possibly up to 150 to 200 strands daily. The hair falls out or breaks and then regrows. This is the pattern of hair growth in the human body. The majority of men will realize soon enough that they are losing more hair than before and that it is not returning. Male baldness is characterized by hair loss on the scalp. The hormonal levels in males typically fluctuate throughout the course of their lifespan, particularly as they age. It is estimated that 50 million males in the US are suffering from baldness, of which half of the men are affected by the age of 50.

There are three possible cures for male baldness available on the market right now. Men who do not wish to go bald can cure hair loss with hair transplant surgery, finasteride tablets, or minoxidil lotion. The surgery is uncomfortable and costly, but finasteride can impair sex and fertility, and unfortunately, minoxidil is not effective for everyone. Many scientists and researchers are working on the baldness issue to achieve the best possible results. A recent innovative step has been taken by Xudong Wang and his colleagues at the University of Wisconsin-Madison, who created a wireless patch that clings to the scalp and creates electrical stimulation by capturing energy from random body motions.

The experiment was done on shaved rats, who were subject to the triboelectric effect, through a flexible patch that was applied to the skin of the rats. When compared to minoxidil lotion and inert saline solution, the generated electric pulses triggered quicker hair regrowth. Wang and his team have now created a hat that completely covers the entire scalp in triboelectric materials to encourage hair growth. As the skin loses its capacity to develop new hair follicles after several years of baldness, the hat will only function in men who are actively losing their hair or have just been bald.The Xudong Wang team is in the process of obtaining authorization to test it on humans in a clinical investigation.
