Hair loss and itchy scalp are two common problems that can affect your appearance, confidence, and comfort.

What Is Red Light Therapy?

Red light therapy, also known as photobiomodulation or low-level laser therapy, is a non-invasive and painless treatment that uses red or near-infrared light to stimulate the cells in your body. The light penetrates deep into the hair follicles and the scalp, where it activates the mitochondria, the energy-producing parts of the cells. This boosts the production of adenosine triphosphate (ATP), which is the molecule that stores and transports energy in the cells. As a result, red light therapy can enhance the cellular metabolism, blood circulation, oxygen delivery, and inflammation reduction in the scalp and hair follicles.

How Does Red Light Therapy Work for Hair Loss and Itchy Scalp?

Does red light therapy work? Red light therapy can help with hair loss and itchy scalp by addressing the root causes of these conditions. For hair loss, red light therapy can stimulate the hair follicles to enter the anagen phase, which is the active growth phase of the hair cycle. This can increase the number and thickness of the hairs, as well as prevent premature hair shedding. Red light therapy can also improve the quality and strength of the hair shafts, making them more resistant to breakage and damage.

For itchy scalp, red light therapy can reduce inflammation, which is often associated with scalp conditions such as dandruff, psoriasis, eczema, or dermatitis. By lowering the levels of inflammatory cytokines and prostaglandins in the scalp, red light therapy can alleviate the symptoms of itching, flaking, scaling, redness, and irritation. Red light therapy can also modulate the immune system and balance the microbiome of the scalp, which can prevent infections and allergic reactions that can trigger itchiness.

What Are the Benefits of Red Light Therapy for Hair Loss and Itchy Scalp?

Red light therapy has many benefits for hair loss and itchy scalp, such as:

• It is safe and effective. Red light therapy has been proven by numerous studies to be a safe and effective treatment for hair loss and itchy scalp. For example, a 2014 meta-analysis of 11 randomized controlled trials found that red light therapy significantly increased hair density and hair count compared to placebo1. A 2019 systematic review of 22 studies concluded that red light therapy improved scalp health and reduced itchiness in various scalp disorders2.
• It is painless and comfortable. Red light therapy does not use heat or chemicals that can harm or irritate your scalp. It is a gentle and relaxing treatment that does not cause any discomfort or side effects. You may feel a slight warmth or tingling sensation during the session, but this is normal and harmless.
• It is convenient and easy to use. Red light therapy can be done at home with a portable device that you can wear on your head like a cap or a band. You only need to use it for a few minutes a day, depending on the instructions of your device. You do not need to visit a clinic or a salon for this treatment, which can save you time and money.

How to Use Red Light Therapy for Hair Loss and Itchy Scalp?

If you want to try red light therapy for hair loss and itchy scalp, you need to follow these steps:

• Choose a device that suits your needs and budget. There are many devices available on the market that use red light therapy for hair growth and scalp health. You should look for a device that has a wavelength between 630 nm and 670 nm, which is the optimal range for stimulating hair follicles and reducing inflammation3. You should also check the power output, battery life, coverage area, warranty, and customer reviews of the device before buying it.
• Follow the instructions of your device. Different devices may have different settings and durations for optimal results. You should read the manual carefully and follow the instructions of your device. Generally speaking, you should use red light therapy for hair loss and itchy scalp every day or every other day for at least 10 to 20 minutes per session. You should also make sure that your scalp is clean and dry before using the device.
• Be consistent and patient. Red light therapy for hair loss and itchy scalp is not a quick fix. It takes time for your cells to respond to the light stimulation and produce visible changes in your hair and scalp. You should use red light therapy regularly for at least three to six months before expecting noticeable results. You should also monitor your progress by taking photos of your scalp every month to compare the changes.
