The low level laser hair loss therapy is no risk of any kind of burning to the scalp or any risk of skin cancer. The lasers are cold lasers and the lasers are used need less energy than a 40-watt light bulb. It has not radioactivity or dangerous energy, and do not have the thermal-component to cut, burn or vaporize.

A researcher, Andre Mester, was working at Semmelweis University, in Budapest. He developed a theory that was similar to the UV theory except instead of using UV lights, he used cold laser light. He believed that UV rays from the sun would lead to cancer and so would cold laser light.

Mester tested his theory but shaving the fur of two groups of mice in which he constantly exposed one group to cold laser light. The control group was not exposed to the cold laser light at all. To Mester's surprise, the mice did not develop cancer but instead grew back their fur much faster than the control group.
