The Foundation Light Therapy (FLT) devices deliver Low-Level Laser (LLLT) to the scalp through 300 lasers. These lasers increase blood circulation, stimulate hair follicles, and are shown to reduce thinning and promote hair-growth. Our unique product designs provide uniform coverage over the entire scalp for consistent effectiveness. The Optima offers an advanced, 300-diode cap that is custom-fitted to your scalp. This provides expanded coverage and exceptional comfort, with no need for a sports hat. This model has a more sleek, less intrusive design that is customizable, flexible, durable, and comes with a lifetime warranty.
