This is the hairbrush equipped with nine lasers and six LEDs that help stimulate follicles and leave hair fuller and healthier-looking. Low-level laser therapy has long been demonstrated in clinical trials to be an effective treatment for hair loss, and this brush combines safe beams with 660nm LEDs to boost circulation on the scalp, which helps channel more oxygen and nutrients to limp locks. Effective for men and women, the brush is recommended for use in three weekly sessions of 15 minutes, and users have seen results in as few as eight weeks. The 26 comfortable bristles can be removed for cleaning, and the cordless design enables convenient use without a tangling cord. A two-minute charge with the included AC adapter provides up to 45 minutes of use. 7 1/2" L x 2" W x 1 3/4" D. (11 oz.)
