Are you struggling with hair loss and seeking a safe and effective solution? Look no further than our ultimate guide to the best red light therapy for hair growth.
Hair loss has many causes, from genetics and hormonal changes to stress and poor nutrition. But whatever the reason, red light therapy can be a game changer when it comes to promoting hair growth.
Here is the reason why red light therapy Is one of the best way to grow hair.
At its core, red light therapy works by stimulating the hair follicles and increasing blood flow to the scalp. This increased blood flow helps deliver vital nutrients and oxygen to the hair follicles, promoting follicle cell regeneration.
Additionally, red light therapy reduces inflammation and improves cellular metabolism and the scalp environment. You can check out our other article on red light therapy for hair loss, which contains detailed research.
Red light therapy may be the perfect solution if you're tired of expensive hair transplants or harmful medications with harsh side effects.
In this ultimate guide to the best red light therapy for hair growth, we delve into the science behind this revolutionary treatment, explore the most effective devices on the market, and provide tips for getting the most out of your red light therapy procedure.
Research on the best red light therapy for hair loss
We believe that widely available and easily accessible red light therapy for hair loss is the best option for reaching more patients.
Extensive and effective working principles
Red light therapy lends itself to a wide range of applications due to its cellular-level working principle. In addition to hair growth, it is also used to improve athletic performance[1], burn fat[2], and more.
Back to hair growth involves exposing the scalp to red light, which penetrates the skin and is absorbed by the cells. This increases blood flow to the scalp, hair follicle activity, and collagen production in the scalp, stimulating hair growth. As a result, it is effective for most types of hair loss, including androgenetic alopecia (AGA) and nutritional deficiencies.
However, consulting with a medical professional is essential to determine if you are a suitable candidate for red light therapy. It is not recommended for those who are photosensitive or have severe skin conditions.

Effective wavelengths for hair growth
In a comparative experimental study[3] on hair growth, we discovered that the most effective wavelength range for hair growth is 630–670 nm. Surprisingly, the best treatment effect is achieved by combining red light at 655nm and infrared light above 800nm. These wavelengths respectively stimulate the activity of hair follicle cells and accelerate blood flow to the scalp, resulting in optimal hair growth.
A affordable and safer light source—LEDs
Pinar Avci's 2013 study[4] summarizes the results of clinical trials conducted by several leading medical institutions for different wavelengths and light sources. While some physicians use "spot" focused lasers to treat deep tissue lesions, LEDs are becoming more common in dermatology due to the relatively large area of tissue that needs to be irradiated.
Treating the entire scalp with a "spot" focused laser is not practical. However, many patients with hair loss desire extensive treatment of the scalp hair follicles. Laser devices are often offered in clinics or sold as part of expensive professional helmets. When LEDs are available as an affordable and easy-to-combine wavelength option that requires relatively low operator expertise, there is no reason not to consider them.
The most effective wavelengths for red light therapy for hair growth are 660 nm and 850 nm. As an affordable and safer option, we recommend LED light sources.
Red light therapy for hair loss at home: What to Look For?
This section will discuss the factors you should consider when purchasing a red light therapy hair growth device, whether a home-grade or professional-grade device that must meet your needs.
-
Wavelength: Combining 620-670nm and 800-850nm can achieve the best hair growth results.
-
FDA Approval & Electric and Magnetic Fields (EMFs): FDA approval and a value of 0 EMFs help reduce the possibility of negative effects.
When looking for the perfect device to meet your needs and budget, consider the following factors:
- Product type: The coverage and output power will gradually increase from combs or handheld devices to hats or helmets. Consider a comb or handheld device if you only have localized hair loss. Otherwise, a hat or helmet product is more suitable for you.
- Types of light sources: Lasers can be more expensive than LEDs and provide faster results. However, if you don't have the budget or are more concerned about the possible risks of lasers, we recommend safer and effective LEDs. In addition, their scattering characteristics are more suitable for extensive scalp treatments.
Finally, remember to evaluate your future user experience.
-
Convenience at home: Check out the instructions or video to understand the product before purchasing. For example, why does this helmet weigh so much? Why must it be plugged in and used in a stationary position? Please don't complain about the product's limitations only after purchase; know them beforehand.
-
Learn about products from reviews: Try to choose a brand with a low probability of defective products. You can find the brand's ratings on major shopping platforms and review sites to understand durability.
