Understanding Low-Level Laser Therapy for Hair Loss

If you are experiencing hair loss, you’ve most likely come across low-level laser therapy (LLLT) as an effective solution to restore your hair. However, you might be wondering what the heck LLLT is and how it can help with sustainable hair growth. I mean, it just lights, right? Well, not exactly. In fact, there is a lot of science and clinical studies built around the effectiveness of low-level laser therapy for hair loss. So, let's dive in and discover why LLLT might be the best solution for your hair loss and how this science works.

What is LLLT?

Low-level laser therapy (LLLT) uses laser light to enhance cellular function, also known as the process of photobiomodulation. This rapidly-growing technology offers several clinically studied benefits like hair restoration, promoting wound healing, and even preventing tissue damage.

While LLLT is gaining popularity, the science behind LLLT for hair loss started back in the 1960s when a team of researchers tested the effects of cold lasers on cancer. They found that the mice they had shaved for the testing with cold lasers began regrowing their hair faster than the other groups. This discovery leads to thousands of clinical studies built around LLLT technology for hair growth. Fast forward to today and LLLT technology is a leading non-invasive solution for hair restoration.

How Does LLLT Work for Hair Loss

LLLT devices work in five ways to help you hit your #hairgoals.

Increases Blood Flow

LLLT increases anagen hairs through the process of nitric oxide photodissociation. Nitric oxide acts as a vasodilator that helps widen blood vessels, which increases blood flow, encouraging hair growth.

Boosts Oxygen Delivery

When the low-level infrared lights interact with your scalp, the laser separates two critical factors of the hair loss equation: nitric oxide (NO) and an enzyme is known as cytochrome c oxidase (Cox). With these elements separated, more oxygen is able to reach cells (aka increased cellular respiration.) As a result, more life-giving oxygen is delivered to hair follicles, allowing them to grow like they did in your 20s.

Reduces DHT Production

5-alpha reductase is an enzyme that converts testosterone into the hair loss hormone DHT (dihydrotestosterone). While LLLT does not block DHT, it does inhibit the production of the 5-alpha reductase enzyme, thus halting the conversion of testosterone into DHT.

Promotes Stem Cell Growth

Our illumiflow laser caps technology works to activate specific shock proteins to boost stem cell growth in your hair follicles. This particular shock protein is also known as HSP27, which aids in cellular health. This process encourages hair growth at the cell's innermost layer, the outer root of each sheath, and within the top layer of skin (at the epidermis cells where a structural protein called keratin is produced).

Causes Beneficial Inflammation

Not all inflammation is harmful. In fact, inflammation is a natural immune response that can encourage hair growth (in smaller doses). The focused effect of red light on the scalp (LLLT) helps to instigate this helpful form of inflammation, thus promoting new hair growth without becoming uncomfortable or resulting in any adverse side effects.

Using Low-Level Laser Therapy for Hair Growth

As mentioned above, low-level laser therapy has many uses, but hair restoration is one of the most popular uses of LLLT technology. Today you can receive low-level laser therapy treatment at a doctor's office or buy an FDA-cleared device for discreet, at-home use. FDA cleared devices like the illumiflow laser caps are Class II Medical devices, proven to be safe and effective for home use.

Why LLLT is Effective

So what makes laser hair growth so effective? Well, it all comes down to cold lasers and red light.

Cold lasers are used in LLLT to produce a specific form of red light that provides low levels of heat to the surface of your skin. This light, in turn, energizes the mitochondria of your cells, helping support cell repair and encourages cell health.

Decades of research have proven that coherent red light between the wavelengths of 630nm and 670nm is the optimal frequency for stimulating new hair growth, which is why all illumiflow products have been designed and formulated to meet these standards.

LLLT vs. Hair Transplants

Choosing between LLLT therapy or a hair transplant comes down to a few factors – cost, safety, and effectiveness. There are two main techniques used for hair transplants.

The first technique is known as follicular unit transplantation (FUT). With a follicular unit transplant, the surgeon will cut a strip of your scalp, separate it into sections, and then implant it into the areas you are experiencing balding.

The second technique is known as follicular unit extraction (FUE). With this method, the surgeon will use a needle to make holes in your scalp where there is balding. Then, the surgeon transplants tiny hairs to this area. This procedure might take a few more sessions to be completely effective. Hair transplants are safe, but you might experience some side effects like:

  • Infection
  • Itching
  • Inflammation
  • Swelling
  • Bruising
  • Temporary loss of new hair
  • Unnatural looking placement

 

The success rate of a hair transplant is 10-80% and the estimated cost can be anywhere between $4,000 to the upwards of $15,000. For prolonged success and to reduce the risk of balding in not treated areas, the use of Minoxidil and LLLT might be recommended by the surgeon.  

LLLT, on the other hand, is an entirely non-invasive and pain-free hair restoration therapy. With LLLT, strategically placed laser diodes are housed in a laser cap and placed on your head. Each laser cap manufacturer has different standards for use, but at illumiflow, our laser caps were designed to be used for 30 minutes every other day. With LLLT, you will typically see results in about 4-6 months, and the cost can be anywhere from a few hundred dollars to a few thousand.

LLLT has no known side effects,so it works well with other hair loss solutions like minoxidil, lifestyle changes, and even hair transplants.

Lasers vs. LEDs for Hair Growth

With low-level laser therapy growing in popularity, there is no shortage of at-home solutions available on the market. However, they are not all created equal. Some laser caps use both LEDs and laser diodes; others, like illumiflow, opt only to use premium lasers. So why is this important? Well, the clinical studies developed around LLLT focused on laser diodes, not LEDs. In fact, LEDs do not produce the proper power or coherence to reach deep tissue, which is essential to promote cellular change. LEDs also do not operate at a high enough wavelength in comparison to LLLT for the most substantial results.
