The innovative COMFORTFLEX design ensures ease of use, adjustments to fit conviniently and a lightweight and portable solution, so that nothing comes between you and your hair restoration. So how does it work? The Laser Band delivers therapeutic light energy to your hair follicles through the use of nourishing medical-grade lasers (no LEDs). Hair follicles are stimulated at a cellular level, promoting hair growth and restoring your hair’s natural growth cycle from within, resulting in improved density and fullness.
