LLLT stands for Low Level Laser Therapy. There are more and more hair loss treatment devices out there using LED lights as opposed to laser lights for the treatment hair loss. Some are claiming that LLLT stands for Low Level Light Therapy. I even saw an advertisement for one device that quoted a study that used lasers where there device only used LED's, claiming that LLLT meant low level light therapy. It does not.

There are hundreds of studies using LLLT for hair loss treatment which show positive results. All of these studies use lasers, not LED's. Here is a search result for LLLT on Pu-Med which allows you to read many studies on this.

The reason LED lights do not work for hair loss is because LED light does not penetrate the skin deep enough to affect a hair follicle. LED light only penetrates the skin 2 to 3 millimeters, while hair follicle roots are up to 6 or 7 mms below the skin surface. The light needs to penetrate deep into the skin in order to stimulate growth. Laser can do this, while LED can only penetrate 2 to 3 mms into the skin,. not nearly enough to stimulate the follicle much lower in the skin.

All of the laser devices on our website use lasers exclusively: https://www.thefreedomstore.ca/hair-loss-lasers-s/745.htm
