Red light therapy, also known as cold laser, soft laser, and Low-Level Laser Therapy, is a safe form of light treatment that’s being used more and more to treat the genetic forms of hair loss (androgenetic alopecia or pattern balding) common in men and women over 35.
Red light therapy has been found, to increase blood flow (microcirculation) in the scalp and stimulate metabolism in catagen or telogen effluvium follicles.
The result is an accelerated production of anagen hair – new hair (stimulation of epidermal stem cells in the hair follicle bulge and shifting the follicles into anagen phase).
Both red light therapy and near infrared light therapy have been known, to stop hair loss and to promote regrowth of fuller thicker hair. Sometimes light therapies are called by other names such as laser soft laser low-level light therapy, photo bio-modulation (or PBM for short).
Whatever they are called, red light therapy is a safe light-based treatment becoming popular as a method to stop hair loss, including genetic forms, which are a very common problem for men and women over age 35.
Red light therapy for hair loss typically uses LED lights, which emit a red light in a specific range of wavelengths (630-670 nm), that have been established effective at causing hair to grow.
For men, the most common balding pattern involves a receding hairline and hair loss at the crown of the head, while for women hair loss more often involves diffuse thinning of the hair all over the head. Either way, red light therapy can help.
With the addition of certain hair serums, results can be obtained in only a few weeks, especially if paired with red light therapy.
Everyone is different, and although there are not very many side effects of red for near infrared light, therapy it’s always possible an individual could experience problems that no one else does. Therefore, when beginning with any type of light therapy the patient should look for the advice of a specialist.
Red light therapy can stimulate hair growth but it cannot grow hair in places where it has never existed. It can improve the quality of the hair that grows by increasing the blood supply to the area, making sure that the growing hair is getting the nutrients it needs to be healthy.
Red light therapy has many other benefits including increasing the production of collagen as an anti-aging defense.
Depending on the cause of hair loss, the mode of treatment will vary as well. No known therapy will work for all forms of hair loss, as there is no one-size fits all treatment for it. For example, if you are having hair loss because of a certain medication, you will not stop losing your hair unless you stop using that specific medication. Moreover, the earlier a treatment is started, the better the chances of success through its use.
There isn’t much that can be done to resurrect a hair follicle once it has died, much like when brain cells die. Therefore, it is suggested that when using any treatment for hair loss, beginning early will be critical to optimal success. The primary target of Low-Level Laser Therapy and red light hair loss therapies are people who have temporarily lost their hair due to issues such as emotional and physical stress, medication side effects, or other conditions, such as male pattern baldness or menopause.
Wait two to three months to see significant results. This is not an overnight process. Although hair cells typically divide and generate fast, it will not be an overnight process. Stop stressing out and let your body do its work. You did not lose your hair overnight, it is not going to grow back overnight either. Although, what it might do overnight is stop falling out, which is a great start.
Red light therapy produces oxygen as a byproduct of its process. Use a daily topical antioxidant for the scalp to lead to faster and better results.
This will depend on the type of device you use. Follow the manufacturer’s instructions and do not over bake. Longer treatment times do not necessarily mean it will yield better results. You do not need to spend an hour or so under the light in the hopes that your hair will grow faster.
