The laser hair loss comb can help along with a transplant to prevent further hair loss. However, while there are plenty of products on the market that claim they can restore hair, nothing can restore hair except a hair transplant. Don’t buy into miracle cures in the form of shampoos, lotions and pills that claim hair re-growth. Doctors do recommend a laser hair loss comb to help prevent your non-transplanted hair from falling out. The laser hair loss comb, however, is most effective when used in combination with a transplant. It will not grow back hair.
