Firm says its bald comb has teeth

Drawing a special comb over a balding pate could restore some real hair, a Florida company says.

The Food and Drug Administration has cleared for sale a hand-held laser device to promote hair growth.

The Hairmax Lasercomb increases the numbers of thick hairs on the scalp, according to 26-week clinical trials conducted by its manufacturer, Lexington International LLC.

The device combines a low-level laser with a comb. When drawn through the hair, the laser strikes the scalp to promote hair growth, according to the company.

The device, sold online for $545, is the only drug-free product meant for Hair Loss use in combatting hair loss that's won the endorsement of the FDA, the company said.
