Best Red Light Therapy for Hair Growth

Best Red Light Therapy for Hair Growth

Solutions and products for thinning or balding hair have been promoted for hundreds of years in one form or another. It actually wouldn't be too much of a stretch to say that people have been promoting hair loss treatments for thousands of years in various imaginative ways. 

Ancient Egyptians, for example, used to sell potions and lexers combining ground-up donkey hooves, of all things. Savvy Roman traders would ply crushed berries with fig tree oil as a hair growth potion, and even Hippocrates himself touted a mixture of pigeon droppings, opium, and horseradish as a 'miracle' hair treatment. 

Modern Improvements

In these modern times, we have benefited from the remarkable progress of medical sciences for our afflictions and technological advancements for efficiency. Hair loss treatments have evolved greatly since those quite bizarre potions of old, and consumers now have a range of relatively efficient products available to treat hair loss issues. The donkeys are safe, you will be relieved to know.

While there is no miracle all-encompassing ‘quick fix’ for complete hair loss restoration just yet, there have been vast improvements over the last decade or so, and many of the products currently available are indeed quite viable.

However, in a vast sea of potions, creams, tonics, and even surgeries, there is one solution in particular that has become immensely popular for the age-old issue of hair loss and androgenetic alopecia: That solution is known as red light therapy, and through this short article, we are going to explain what it is, how it works, and, more specifically, which type of red light therapy might be described as the best for you. 

Let's get to it. But first, a very quick delineation of red light treatment.

What Is Red Light Therapy?

While we do have more extensive articles covering the subject throughout our website, for the unfamiliar, let’s talk about the basic premise of this exciting and now booming technology.

You might remember the high school class when your science teacher demonstrated light passing through a glass prism and the various rainbow colors that it would emit. While many of us paid too little attention at the time, the whole point was to show that different light colors emit different wavelengths, which are measured in nanometers.

Red light happens to contain 620 to 750 nanometers, which, it turns out, is excellent for promoting hair growth. Other color ranges promote different benefits. Ultra Violet, for example, contains 100-400 nanometers, which just so happens to be the sweet spot for tanning and is commonly used in tanning salons. The same principle applies to other light-based technologies, such as radiology.

That's the science of it, albeit the very brief, basic version. In layman's terms, hair follicles dance with joy when medical-grade laser diodes shine red light upon them. In turn, hair growth is duly promoted. 

Science Meets Tech

The Capillus Laser Cap innovation merges the science of our FDA-cleared professional-strength laser therapy with the technology of a wearable device in the form of a cap.

Our laser cap revolutionized the hair restoration industry over a decade ago by making professional-strength laser therapy available to hair loss patients from the comfort of their own homes and was the first laser therapy cap to be cleared by the US FDA for the treatment of androgenetic alopecia. 

Capillus Laser Caps are designed, engineered, and assembled in our US-based, ISO13485-certified facility, using the highest quality, medical-grade lasers, and are backed by our elite Physician Network.  

Other Devices

In addition to our ever-popular Capillus laser caps, the industry has spawned a range of alternative red light devices specifically for the treatment of hair loss and thinning hair. Let's take a look at the options currently available:

Handheld Devices

Handheld devices are compact and portable units that emit red light wavelengths. They usually come with a handle or a wand-like design, making it easy to maneuver and target specific areas of the scalp. Handheld devices might be a choice for individuals who prefer more control over a specific treatment area, possibly at the expense of convenience, comfort, and even distribution, when compared to a cap.

Panels (With or Without Stands)

Red light therapy panels consist of an arrangement of diodes in a panel format, which can be stationary or fixed to adjustable stands, allowing the user to position them at different angles - similar to the early UV light tanning stands. 


Red light therapy helmets look akin to bike helmets in many ways and are fitted with red laser diodes or LED lights on the inside. The helmet distributes red light therapy evenly across the scalp and, similar to the laser cap, provides hands-free operation and complete coverage of the head.

Combs and Brushes

Red light therapy combs and brushes feature built-in red LED lights or lasers along the bristles, allowing you to combine hair grooming with red light therapy. As you comb or brush your hair, the red light stimulates the scalp and hair follicles. There have been questions about the general quality of combs within the industry, with some critics meeting combs with an air of skepticism when compared to the laser cap.

Bottom Line - Which One Should You Choose?

The truth is that each device has its own pros and cons for separate reasons. While handheld devices, panels, helmets, and even combs have all made their way into the market of red light therapy, in terms of ‘the best red light therapy for hair growth,’ our Laser Cap is the clear market leader.

Obviously, we are going to appear biased, but the facts speak for themselves and are backed by a comprehensive 17-week clinical study in which the Capillus Laser Cap demonstrated a 51% increase in hair counts. What sets the Capillus Laser Caps  apart from other products is the comprehensive scalp coverage and extensive coverage of 272 light nodes - in comparison to just one single light node available to a laser comb, for example. 

Our Laser Cap combines the technology of a clinic-based fixed device with the effortless convenience of a portable device. By combining the best of both worlds, we bring you a red light therapy device that is both effective and effortlessly adaptable to your lifestyle.
