Dual Laser & LED brush uses technologies proven to promote richer fuller hair. Worlds first! The Laser & Light Technology in this lightweight handheld device is the same technology used in hair salons worldwide to revitalize thicker richer looking hair. Dual technology using Low Level Laser Technology (LLLT) and LED stimulating therapy (LEDT). Both of these technologies provide the much needed light energy required for healthy hair. The treatment is cost effective safe for the home and more convenient then going to a hair specialist. Two series of 36 LED stimulators help to penetrate the scalp with light to stimulate and massage the scalp. The Laser Light is reflected across the entire length of the device to give a consistent beam for greater effectiveness. We recommend using our brush three times a week 10-15 minutes per use with most users seeing results in 8-16 weeks.
