How effective is REVIAN for someone with a bald spot on the back of the head?
The REVIAN cap is designed to cover the entire head. It completely covers the front hairline, side hairlines, and the back of your head. It also adjusts to fit a wide range of head sizes. Unlike other plastic helmets using lasers, LEDs emit a much wider angle of light, bathing the entire scalp in overlapping cones of light. Laser products are much more tightly focused and only target discrete spots on your scalp. We’ve proven that our LED light penetrates the skin fully to the needed levels to affect the cells, but with more complete coverage compared to laser diodes.
