What is Low Level Laser Hair Therapy?

Low Level Laser Hair Therapy (LLLT) is a form of laser light treatment, sometimes known as Photobiomodulation. Laser light treatment has been around for over 50 years, having been discovered in Hungary in 1967 by a medical scientist called Endre Mester. Mester was performing experiments on tumours in rats and noticed that the light beam he was using produced enhanced hair growth and wound healing in the rats [1].

Since then, devices, techniques and treatment protocols have been developed, based on extensive research into light wavelengths and frequencies. LLLT is now an established, FDA approved treatment for a range of skin conditions and wound management, as well as an effective alternative to drugs or transplants in people experiencing hair loss [2]. LLLT for hair loss uses low intensity infrared light to stimulate cell activity and blood circulation in the skin tissues, where the hair follicles sit.

What are the benefits of LLLT?

LLLT has been shown to be effective in stimulating DNA, endorphin and collagen production. These key effects, together with helping to reduce inflammation, improve blood circulation and boost immune responses, produce several noticeable benefits. Targeted LLL Hair Therapy leads to enhanced hair thickness, fullness and strength. It is at least as effective as drug treatment and studies are looking into whether combining LLLT with oral or topical minoxidil [3] leads to even better outcomes.

As well as boosting hair growth, LLLT can also slow down and prevent existing hair loss. Studies have shown at least 4 out of 5 people experience slowing or stopping of hair loss, and over half see new hair growth.

A key feature of LLLT is that it is non-invasive and there is no need for any “down time” from activities of normal life. Sessions can be scheduled to suit you, with no discomfort or after-effects.

Who can have LLLT?

There are multiple reasons for hair problems and almost anyone can benefit from LLLT. Hair loss and hair thinning can be hereditary (in both men and women) and can also be triggered by stress or hormone imbalances, such as those experienced during menopause. Medical treatments, including chemotherapy, can cause hair loss and some people may find their hair does not grow back as it was previously.
