PAINLESS, SAFE AND EFFECTIVE LASER TREATMENT Laser Hair Therapy (LHT) or Low-Level Laser Therapy is a non-surgical, scientific approach in the treatment of hair loss, thinning hair, and scalp problems. LHT has been tested for effectiveness and safety for over 30 years all around the world. When it comes to non-surgical cosmetic treatments, LHT is considered one of the best treatments for hair loss. Utilizing a device that contains 160 therapeutic soft low light level lasers, LHT delivers light energy from about 160 laser diodes covering an individual’s head. LHT functions on the same scientific principle, as that of photo-bio-stimulation; laser light stimulates cell metabolism and helps damaged cells to repair themselves.
