The LaserBand 41 is a home use medical device that delivers therapeutic light energy to your scalp. This nourishing laser light stimulates hair follicles, reverses thinning, increases density & fullness, restores your hair’s natural growth cycle and promotes hair growth. The unique band design incorporates patented hair parting teeth to part your hair during treatment to maximize laser light delivery to your follicles. The hair parting teeth, the laser light intensity and laser light density work in unison to provide a highly effective treatment. Without hair parting teeth, the hair can block a majority of the laser light energy from reaching the follicles. The LaserBand 41 is compact, lightweight, comfortable, portable and convenient for home use or while traveling. No heavy battery packs to carry around. The LaserBand 41 delivers therapeutic light energy through 41 Medical grade lasers (No LEDs) and uses patented hair parting teeth to deliver light energy to scalp. The treatment time is as little as 3 minutes, 3 days a week. The flexible band design adjusts to fit most head sizes for a very comfortable treatment.
