Low-Level Laser Therapy

Men and women dealing with hair loss have numerous options available to them for treatment. While some individuals experience good results with options like finasteride and minoxidil, others find that these prescription and over-the-counter remedies simply do not provide the results they expected. Low-level laser therapy is another outstanding option that can help slow hair loss and perhaps even regrow hair.

What Exactly is Low-Level Laser Therapy?

Low-level laser therapy (LLLT) is also called cold laser therapy and near-infrared laser therapy and uses low-level light energy to treat numerous conditions. These include not only hair loss, but also arthritis, back pain, carpal tunnel syndrome, and others. There are roughly 24 cold laser devices that have been approved by the FDA; some are sold online and are intended for at-home use while others are used in clinics and professionals’ offices across the country. People prefer LLLT to many other options as it is painless, noninvasive, and has no known side effects.

How LLLT Helps Hair Loss

Scientists and researchers aren’t sure exactly how LLLT provides positive benefits, but they believe that the penetrating cold light may possess anti-inflammatory properties that boost hair follicle health. Some believe that LLLT can repair and even restore connective tissues, and there are some who claim that LLLT relieves their pain better than some OTC and prescription pain relievers, as well.

Studies on the use of LLLT to prevent hair loss and stimulate hair growth are very limited. Those that have been conducted are incredibly small scale and they were not well-controlled. Before buying an LLLT device to use at home, it’s important to remember that not everyone responds the same way to the treatment, and not all machines can deliver the same wavelength of light. Therefore, differences in the duration of your treatment, the wavelength, and the condition causing your hair loss can all have a tremendous impact on your results.

The Studies

One study conducted in the 1960s – back when LLLT was still in its infancy – found that mice who were treated with cold lasers healed faster than those that were not. Another study published in 2014 found that LLLT slowed the progression of Alzheimer’s disease in mice. Finally, a small-scale 2014 study looked specifically at the therapy’s ability to reduce the effects of hair loss. Of 44 men between the ages of 18 and 48, 39% experienced increased hair growth over a 16-week treatment period.

Who Should Try LLLT?

Low-level laser therapy is noninvasive and painless, and it will not interact with other treatments being used to help slow the progression of hair loss. For that reason, it is generally considered safe for anyone who is interested in giving it a try, but it is important to remember that not everyone will see benefits, and those who do will see a broad range of benefits. In other words, while one person may experience significant hair regrowth, someone else may only see a slight decrease in hair loss.
