How it’s done: It is used much like a normal comb, but not on wet hair. It uses laser phototherapy to stimulate the root and follicle for healthy, new hair growth. Simply plug it in, turn it on, and comb through each section of hair thoroughly. The process should take about 15 minutes.

Complications: Headaches, itchiness and rash may occur.

Recovery: None.

Cost: $600 to $750.
