Can Red Light Therapy Reverse Grey Hair? A Detailed Guide

Grey hair is something that many people dread. It can make you look older, and although it’s a natural part of the aging process, there are ways to reduce or even reverse the effects of grey hair. One such treatment option is red light therapy. In recent years, red light therapy (RLT) has become increasingly popular as a natural remedy for a wide range of health issues. But the potential benefits don’t stop there – some people have begun to explore whether RLT can help with hair-related problems too, such as reversing the graying of hair caused by aging.

What is Red Light Therapy?

Red light therapy is a non-invasive form of photobiomodulation which uses low level red and near-infrared light to treat various conditions. In the simplest terms, it involves delivering a certain wavelength of light onto the body’s tissue to encourage healing and regeneration. It has been used since the early 1960s for medical purposes such as pain relief and wound healing, but has recently gained popularity in the wellness space for its anti-aging and skin health benefits. Red light therapy is believed to stimulate cellular activity which can help to reduce inflammation, boost collagen production, and even revive damaged cells. It’s also been known to promote overall wellbeing by improving energy levels, aiding in muscle recovery, and supporting mood health. With its wide range of potential benefits, it’s no surprise that red light therapy is becoming increasingly popular.

The main way to use red light therapy is with a specialized device such as an LED lamp or laser. These devices generally allow users to adjust the wavelength and intensity of the light they’re using, as well as the duration of their treatment. Treatments typically last anywhere from 5-20 minutes, and while there’s no definitive answer as to how often you should use red light therapy, experts generally recommend two or three times per week for optimal results.

Red light therapy is a safe, natural way to improve your health and wellbeing without any major side effects. However, like with all treatments, it’s important to consult with a healthcare provider before starting a treatment plan to make sure it’s right for you.

How Does Red Light Therapy Work to Reverse Grey Hair?

Studies have shown that red light therapy for grey hair reversal works by stimulating the melanocytes in the scalp. Melanocytes are responsible for producing melanin pigment, which is our natural hair color. As we age, these cells start to become less active and thus produce less pigment, resulting in grey hairs. Red light therapy helps to reactivate these cells and encourage them to produce melanin pigment again, thus restoring natural hair color.

The exact mechanism of how red light therapy works is still being studied, but the general consensus is that it helps to increase blood flow to the scalp and stimulate cellular regeneration. Red light also encourages the release of antioxidants which help protect against oxidative damage caused by free radicals. And by reducing oxidative stress, the hair follicles can stay healthy and produce melanin pigment more effectively.

However, it’s important to note that red light therapy is not a treatment for grey hair overnight. While some people may see results in as little as two weeks, it usually takes at least three months before visible changes are seen. Red light therapy is also not a permanent solution, and regular maintenance treatments may be necessary to sustain the effects.

The Cons of Red Light Therapy for Reversing Grey Hair

Potential Side Effects

Red light therapy has the potential to cause mild to moderate side effects, such as itching, redness, swelling, and blistering of the skin. It is also possible for some users to experience more severe reactions, such as headaches and nausea.

Time Commitment

Red light therapy also requires a significant time commitment, as most treatments are done daily or every few days for a period of four to six months.


Red light therapy can be quite expensive. Depending on the provider, treatments may cost hundreds of dollars per session. For those who need multiple sessions, this can add up quickly and make the treatment unaffordable for some users. However, a red light therapy panel at home may be a more cost-effective option for those who want to continue receiving treatment.

Accessibility Issues

Depending on where you live, red light therapy may not be available at local clinics or spas. This means that users will likely have to travel a significant distance to find a provider who offers this type of treatment. However, investing in a red light therapy panel at home will help you save on time and costs.

Precautions to Take Before Trying Red Light Therapy

Check with Your Doctor

It is always best to consult your doctor before trying any new treatment or therapy. Red light therapy is no exception and it is important to make sure that you do not have any underlying conditions or medications that could interact with the treatment.

Know the Side Effects

While red light therapy is generally considered safe, it can cause some side effects such as nausea, headaches, and skin irritation. It is important to be aware of these potential reactions before starting a red light therapy session.

Wear Eye Protection

Red light therapy is not hazardous to the eyes; however, it is still recommended that you wear protective eyewear during your session. This will help protect your eyes from any uncomfortable glare that comes off the light source.

Follow Directions

It is important to follow the directions that come with your red light device and make sure you are using it correctly. Improper use can result in skin irritation or burns. Additionally, make sure you don’t spend too much time in the light, or you could risk overexposure.

How Long Does Red Light Therapy Take To Reverse Grey Hair?

Grey hair reversal with red light therapy is a gradual process that can take time to show results. Generally, improvements from red light treatments will start to be visible between eight and twelve weeks after beginning treatment. Depending on the user’s age, hair color, and other factors, it may take up to four or five months before significant results are seen.

Not only does red light therapy take time to show its effects, but the user must also remain committed to the treatment in order to achieve desired results. Red light therapy may require two or more sessions per week, and it can be a good idea to get regular check-ins with the doctor or practitioner to ensure that the therapy is being done properly.

It’s important to note that red light therapy is not a one-time treatment. To maintain the results, users will need to continue their treatments for several months and then periodically as needed. The precise amount of time required for red light therapy to reverse grey hair will depend on the individual user and should be discussed with a medical professional.

In any case, red light therapy is a safe and effective way to reverse grey hair without the use of harsh chemicals or invasive procedures. With regular treatments and patience, the appearance of grey hair can be greatly reduced with red light therapy over time.
