Many reviews note that HairMax devices do appear to be effective in promoting new growth of thicker, fuller hair when used as directed. Other users noticed that their hair loss slowed or stopped completely while using the laser devices. Users also appreciate how lightweight and portable the devices are.

It is possible to have slight allergic reactions to the Laser treatment, with redness and itching on the scalp. If you see this reaction please cease the treatment and your scalp will return to normal. Another major advantage to the HairMax treatment, is that is only requires a one of purchase of the device.

All Hairmax®models are designed to last up to 10-15 years. The laser strength is approximately 655 nm, and 5 mw per beam.

So while some grey haired people who have reported that the HairMax worked great in stimulating hair follicles and regrowing their hair, some say that the hair that they was regrown, came back dark!
