According to the American Hair Loss Association, by the age of 35, two-thirds of American men will experience some degree of appreciable hair loss, and by the age of 50 approximately 85 percent of men will have significantly thinning hair. The association adds that hair loss is not limited to men; American women actually make up 40 percent of hair loss sufferers. dermatologists have been aware for several decades about the effect that low level laser light (665 nanometers) has on hair growth. Jonathan Graff of Apira Science joined us live with the new, non-surgical, non-invasive, non-prescription approach for treating thinning hair and hair loss cleared by the FDA for in-home use (one of only two products ever approved by the FDA). The iGrow bicycle helmet-type device is fitted with low level laser and LED lights. It was found in clinical trials to increase scalp hair growth in men by 35 percent and increase scalp hair growth in women by 37 percent when worn on the head for 25 minutes, four times per week, over a 16-week period. The iGrow also comes with headphones that you can plug into your Ipod.
