How do lasers cure baldness?


I’ve read that there is some evidence to show that low-level laser therapy can undo / cure baldness.

I’m curious, how would lasers undo baldness?

Hello. Professional hair thinning guy here. Lasers “help” by stimulating the follicle and the blood circulation to the scalp which in turn helps “promote” hair growth. Lasers CAN help but they don’t really. What helps? Not much.
