There has been a lot of talk about laser therapy for hair loss, including male pattern baldness. Countless number of products are available to the consumer, some with magical like claims about hair regrowth. The most popular products are laser combs and laser helmets that you can have on your head for longer periods of time. But how well do these claims of hair regrowth fit the truth? There have been several scientific studies made to try to answer this but with varying results. According to a newly published review, these studies have serious problems with power, research methods and analysis and stronger randomized controlled trials are needed in order to verify the claimed effect of laser therapy for hair loss. Until then, nothing can be concluded about the efficacy of this treatment.
