Researchers now have a new cure for baldness

In a recent study from the University of Wisconsin-Madison, researchers have discovered that reversing baldness could someday be as easy as wearing a hat.

They developed a noninvasive, low-cost hair-growth-stimulating technology. The method can be a very practical solution to hair regeneration.

The study is published in the journal ACS Nano. The lead author is Xudong Wang, a professor of materials science and engineering.

According to the team, the hair-growth technology stimulates the skin with gentle, low-frequency electric pulses, which coax dormant follicles to reactivate hair production.

The devices don’t cause hair follicles to sprout anew in smooth skin. Instead, they reactivate hair-producing structures that have gone dormant.

That means they could be used as an intervention for people in the early stages of pattern baldness, but they wouldn’t bestow cascading tresses to someone who has been as bald as a billiard ball for several years.

Because the devices are powered by the movement of the wearer, they don’t require a bulky battery pack or complicated electronics.

In fact, they’re so low-profile that they could be discreetly worn underneath the crown of an everyday baseball cap.

Previously, the team had designed and created other energy-harvesting devices.

They had developed electric bandages that stimulate wound-healing and a weight-loss implant that uses gentle electricity to trick the stomach into feeling full.

This new hair-growth technology is based on a similar premise: Small devices called nanogenerators passively gather energy from day-to-day movements and then transmit low-frequency pulses of electricity to the skin.

That gentle electric stimulation causes dormant follicles to “wake up.”

Because the electric pulses are incredibly gentle and don’t penetrate any deeper than the very outermost layers of the scalp, the devices don’t seem to cause any unpleasant side effects.

That’s a marked advantage over other baldness treatments, like the medicine Propecia, which carries risks of sexual dysfunction, depression, and anxiety.

What’s more, in side-by-side tests on hairless mice, the devices stimulated hair growth just as effectively as two different compounds found in baldness medicines.
