A laser comb is a hand-held device used to stimulate hair growth. The actual benefits of using a laser hair comb are not clear. The American Hair Loss Association keeps this comb on its list of "questionable" devices. Similarly, doctors representing surgical hair restoration organizations don't support laser treatments for hair loss. Only one laser hair comb is approved by the U.S. Food and Drug Administration for safety--the HairMax LaserComb--and only for men with mild male pattern baldness. This consumer device, designed for at-home use, purports to yield results in as few as three months and give you an average of 20 percent new hair growth.
Place the laser comb's dual set of teeth on your scalp, starting at your hairline.
Hold the laser comb in the same place for four seconds. After you hear a beep, move it 1/2-inch without lifting it from your scalp. Hold it in the new section of your scalp for another four seconds.
Make more than one pass through your hair with the laser comb. The manufacturer of the HairMax device suggests combing from front-to-back on your first pass and side-to-side on the second pass. Your treatment session should last between 10 and 15 minutes.
Wait a day before using your laser comb again. The device should be used three times a week, but not on consecutive days. Schedule your treatments. For example, you may opt to use the comb on Monday, Wednesday and Friday.
Continue using the laser hair comb even after you notice new hair growth. Like topical and oral medications for hair loss, the device is purportedly beneficial, if you continue treatment.
