How Does Red Light Therapy Fit In?
There are many studies out there that purport that treatments with red light therapy can encourage better regrowth of hair in areas of the scalp that are displaying signs of balding or thinning.
The studies used both men and women showing symptoms of hair thinning to various degrees and shaved a small spot of hair on their heads and took photos of the shave spots and various stages through the treatments. Some of the subjects were treated with the real devices while others were treated with a 'fake' red light device that was a plain red coloured light device.
Although the exact mechanism is not quite known, 2 main actions are believed to be at work.
- Red Light Therapy causes a number of reactions within the cells mitochondria which leads to increased ATP production (cellular energy) and with this increase in energy comes the increase in function of the hair follicles and associated cells.
- Red Light Therapy prolongs the growing phase and can even re-establish the growing phase, even after the hair follicle itself has entered into the resting stage, which in turn cause the shedding phase to be pushed back further.
Basically, your hair grows for a longer period of time before being shed, which is a natural part of the process, allowing new hair to grow back.
The conclusion found that the subjects in the experiments, that got treated with the actual device showed a significant increase in hair regrowth speed as well as a increase in hair count over the treated area!
Improvement is reported after 12 to 26 weeks of use, with reduced hair fall and noticeable hair growth.
It should also be noted, that as of this writing, no ill side effects were reported , nor have any been reported in any experiments with red and infrared light therapy!
