Low-Level Laser Therapy
When Billy Ocean first sang ‘Red Light Spells Danger’, he probably wasn’t referring to ‘Red Light Therapy’, which is believed to support hair regrowth.
Over recent years, there has been an explosion in the availabilty of devices using this type of therapy. One such device, the ‘Laser Hair Comb’, is a handheld device that uses low-level laser therapy (LLLT) to treat hair loss and promote hair regrowth. These devices typically emit low-energy laser light onto the scalp, which is believed to stimulate hair follicles and improve hair growth. This red light penetrates the scalp between 630-670 nm.
The theory behind laser hair combs is that the low-level laser light penetrates the scalp and stimulates cellular activity within the hair follicles. This stimulation can enhance blood circulation, increase nutrient delivery to the follicles, and promote the growth of thicker, healthier hair.
While some studies suggest that LLLT devices, including laser hair combs, may have a positive effect on hair growth in individuals with certain types of hair loss, the evidence is still limited and further research is needed to establish their efficacy.
It’s important to note that laser hair combs are typically most effective for individuals with mild to moderate hair loss. They may not produce significant results for advanced hair loss or conditions where the hair follicles are completely inactive.
FDA Approved
If you are considering using a laser hair comb for hair loss, it’s recommended to consult with a dermatologist or a healthcare professional specialising in hair disorders. They can evaluate your specific condition, provide personalized advice, and recommend appropriate treatment options based on your needs. They may also suggest alternative treatments that have stronger scientific support for hair regrowth, such as FDA-approved medications like minoxidil or finasteride.
