Red light therapy, also known as low-level laser therapy (LLLT), has been studied as a potential treatment for hair loss. While the evidence is still somewhat limited, there are some studies that suggest red light therapy may be beneficial for hair growth.
Red light therapy works by stimulating the hair follicles, which can promote hair growth. It is thought to work by increasing circulation, reducing inflammation, and improving the function of hair follicle cells.
In some clinical studies, red light therapy has been shown to increase hair density and thickness in people with androgenetic alopecia (pattern baldness), as well as in those with alopecia areata. However, more research is needed to fully understand the effectiveness of red light therapy for hair loss.
If you are interested in trying red light therapy for hair loss, it’s important to speak with a healthcare provider or a dermatologist who specializes in hair loss to determine if it is appropriate for you and to develop an appropriate treatment plan. Red light therapy may not be suitable for everyone, and it may also be necessary to combine it with other treatments, such as medications or topical treatments, to achieve the best results.
