You shine light on your head and your hair will grow again. Come on. But I looked into it and it's actually been approved by the FDA as a treatment. There are combs that have red laser light, and caps that you can wear. These are typically treatments for 10, 15 minutes a day or every other day. And they literally have been proven, clinical trials, to slow down hair loss, as well as regrow some aspects of hair in, not everybody, but in the majority of people.
