Grow Laser Cap's photobiomodualtion (PBM) or Low-level laser therapy (LLLT) exposes your hair follicles to low-levels of red and near-infrared light at a nanometre range of 650 nm. These calibrated wavelengths of laser light penetrate the scalp to rejuvenate cells and stimulate cellular metabolism at the follicle. LLLT combats hair loss by extending the growth phase of the hair growth cycle while reactivating miniaturising follicles back to their growth potential. PBM increases nutrient and oxygen-rich blood flow to the hair follicles ensuring the hair follicle matrix has the nourishment for the hair shaft to grow at its thickest and fullest. 280 Medical Grade Laser Diodes FDA Cleared 3 X 30 Minute Sessions Per Week (Automatically timed and Shut Off) One Grow Laser Cap - 280 Laser Diodes One Grow Laser Cap Power Bank One Grow Laser Cap Carry Case One USB cable One Australian and New Zealand AC Adaptor One Grow Black Sports Cap One Instructional Manual Technical Data Grow Laser Cap Diode laser 280pcs Output 5mW Wavelength 650nm Fluence / Joules Per Square CM 3.78 J/CM2 Total Energy 1400mW Grow Laser Power Bank Output 2.1A Frequency 4.5Hz Capacity 8000mAh
