Does laser hair therapy make your hair grow?

The majority of patients who used the Laser Comb in clinical trials reported an increase in hair volume, according to WebMD. The Food and Drug Administration approved the device. Additional FDA-approved laser hair growth devices include the iGrow Hair Growth System and the Theradome LH80 Pro.

The Laser Comb is the third FDA-approved hair regrowth method, alongside finasteride and minoxodil, and is the first that does not use surgery or medication, states WebMD. A low-level laser stimulates hair follicles, promoting hair growth with no side effects. The iGrow uses low-level lasers and LED diodes to stimulate hair growth in men. The Theradome LH80 Pro is only FDA-approved for women, as of 2015.
