A wearable device for regrowing hair

Phys.org   -   Scientific News Websites

Although some people embrace the saying "bald is beautiful," for others, alopecia, or excessive hair loss, can cause stress and anxiety. Some studies have shown that stimulating the skin with lasers can help regrow hair, but the equipmen...
