Half of women experience hair loss by the time they hit 50, according to the North American Hair Research Society. “There are three stages that hair goes through—a growth phase, a transition phase, and a resting phase,” explains Shani Francis, MD, a dermatologist at the University of Chicago who specializes in hair disorders. As you get older, your hair spends more time in the last cycle, which means you’re shedding hair faster than it’s growing back in. Unlike male hair loss, which usually starts as a receding hairline and thinning crown, female hair loss occurs as a gradual thinning all over your scalp. “You may not even notice it coming out in the shower or in your brush—it’s just that over time, more of your scalp becomes visible,” notes Debra Jaliman, MD, a dermatologist at the Mount Sinai School of Medicine.

In 1964, Professor Andre Mester discovered that diode laser (also called low-level laser) can penetrates the surface of the skin with no heating effect, no damage to the skin and no known negative side effects to accelerate hair growth and thickening of hair in the treated areas.

Light therapy is a scientific approach to treating hair loss, which combines the latest technology in cosmetic light energy with a program of hair care products. While newer in the US, Light therapy has been used throughout Europe, Russia, Israel and other countries for over a decade to treat hair loss in both men and women. To achieve maximum benefit from this therapy, it is important that clients adhere to the prescribed regimen and treatment protocols. The treatment program is for clients whose goal is to stop the progression of their hair loss and create the healthiest environment in which hair can re-grow. A strict regimen of treatments should be adhered to for maximum results. For best results, following the first 12 months of treatment, clients should continue to care for their hair using professional hair care products .
