Red Light Therapy for Hair Loss: What to Know


Our hair is a vital part of our identity for many of us. It frames our face, reflects our personality, and can significantly affect our confidence. But as we age, hair can become thinner, weaker, and more prone to loss. This can be a worrying and frustrating experience. 

Why do we lose hair?

A key factor contributing to hair loss with age is a decline in scalp circulation, which diminishes the supply of nutrients and oxygen to hair follicles. This can hinder the follicle's ability to produce healthy hair, ultimately resulting in thinning and loss.

Hair loss can also be influenced by hormonal changes, genetics, and even stress. That's why understanding the root cause of your hair loss is crucial for finding the most effective treatment approach.

Traditionally, hair loss treatments have focused on medications like minoxidil or finasteride, or surgical procedures like hair transplants. While these options can be effective, they may not be suitable for everyone. 

Thankfully, the world of beauty and wellness is constantly evolving, offering new, innovative, and non-invasive solutions to combat hair loss. One such possibility gaining traction in recent years is red light therapy.

But, does red light therapy work for hair loss, and is it the right solution for you?
Let's delve deeper into this technology and explore what this treatment offers.

Understanding Red Light Therapy

Red light therapy, also known as low-level laser therapy (LLLT), uses specific wavelengths of red light (around 650 nanometers) to deliver low-energy photons to targeted areas of the body. 

In the context of hair loss, this could help by:

  1. Enhancing Cellular Activity: Red light exposure can stimulate mitochondria. This increased activity leads to improved energy production and overall cell function.
  2. Promoting Blood Flow: it improves blood circulation, which is vital for delivering essential nutrients and oxygen to hair follicles.
  3. Reducing Inflammation: Chronic inflammation can contribute to hair loss. Their anti-inflammatory properties may help create a more favorable environment for hair growth.

As a result, individuals may experience increased hair density.

Does Red Light Therapy Work for Everyone?

The research on red light therapy for hair loss is encouraging, but it's important to manage expectations. Studies suggest it might be most effective for certain types of hair loss, particularly androgenetic alopecia.

Additionally, individual results can vary. Some people might experience significant hair regrowth, while others might see a slowing down of hair loss or a general improvement in hair health. Factors like the cause of hair loss, treatment consistency, and the specific device used can all influence outcomes.

According to a 2021 article published in the National Institutes of Health's National Library of Medicine, Low-Level Light Therapy (LLLT) is a safe and potentially effective treatment option for promoting hair growth in patients who do not respond or are not tolerant to standard hair loss treatment.

It's important to note that research on red light therapy for hair loss is still ongoing. While studies have shown promising results, more large-scale, long-term clinical trials are needed.

What to Expect with Red Light Therapy for Hair Loss?

Red light therapy for hair loss is typically administered through handheld devices or panels that emit red light. Treatment sessions can be performed at home or in a professional setting. Treatment times can vary, but generally range from 10-30 minutes per session, several times a week.

Here are some key considerations when exploring red light therapy for hair loss:

  1. Consistency is key: Like most hair loss treatments, red light therapy requires consistent use over time to see noticeable results. 
  2. Individual results may vary: As with any hair loss treatment, individual results will vary. Factors such as the severity of your hair loss, scalp health, genetics, and overall well-being can influence how you respond to red light therapy.
  3. Safety First: Red light therapy is generally considered safe for most people. However, it's important to consult with your doctor before starting any new treatment, especially if you have any pre-existing health conditions or concerns, such as epilepsy or are taking medications that increase sun sensitivity.
  4. Cost Consideration: Red light therapy can be expensive; completing the treatment can represent a significant investment, which may be notably higher compared to some other hair loss alternatives.

Complementary Solutions

While red light therapy holds promise as a tool to combat hair loss, it's crucial to remember it's not a one-size-fits-all solution. For best results, consider incorporating a hair loss prevention strategy. This might include:

  1. Maintaining a scalp-healthy diet: Ensure your diet is rich in essential nutrients for hair growth, such as vitamins A, B, and biotin with our Significant Other: Hair, Skin & Nails Supplement.
  2. Managing stress: Chronic stress can disrupt the hair growth cycle and lead to hair loss. Finding healthy ways to manage stress, such as yoga or meditation, can help your overall health and potentially support hair growth.
  3. Using targeted products for thin hair: Look for products formulated to address the specific needs of aging hair and hair loss, such as our collection for lack of volume and thinning hair.
  4. Scalp massages: Regular scalp massages can improve circulation and create a more receptive environment for hair growth. You can incorporate scalp massages into your routine with our Superpower Liquid Comb.


Red light therapy shows promise for hair loss, especially androgenetic alopecia. However, the results vary. Consult a dermatologist or trichologist (a hair loss specialist) to see if it's right for you and explore combining it with diet, stress management, and targeted hair products for better results.
