In The News: Can Lasers Stimulate a Hair-Growth Spurt?

IMO, this is the craziest "theory" I have heard in a long time...you decide.

Do Laser Combs Work?

Story Highlights:

• A number of companies sell handheld, low-intensity lasers for home use that are intended to stimulate hair follicles, typically three times a week for 10 to 15 minutes.
• Scientists say that low-level lasers are safe and likely do act on cellular compounds that can spur hair growth.
• It's best to try the laser before your hair follicles are too damaged, doctors say. "If you've got a shiny bald head it won't do anything,"
• The only home laser device cleared for hair growth by the Food and Drug Administration is the LaserComb, which claims to increase hair growth in men.
• researchers found subjects using the LaserComb for 26 weeks saw an average increase of 17 hairs per square centimeter, or 7%, compared with a decrease of nine hairs in a control group using a sham device.
• So far the only side effects reported with the lasers have been itching and tingling of the scalp.
