What is the big deal about low-level laser therapy – LLLT?

Hair 4 Life Medical - Dr. Kelemen

We see ads on TV, in the large chain stores like Costco that have LLLT caps for sale and promise new hair, fuller hair, thicker hair. The claims are a little far fetched but what I have seen in my practice is that patients who use LLLT regularly loose less hair and their hair is healthier thicker. Now does it grow NEW hair? NO, it does not! I know, I know what it says on the box. What it does do is help those hair follicles that are struggling to perk up from the increase in blood flow that you would lose them without this treatment!

So why do we lose our hair?

The medical consensus is that every day, most people lose about 100 hairs from their scalp. While the majority of people grow those hairs grow back, some people don’t due to:

  • age
  • heredity
  • hormonal changes
  • medical conditions, such as lupus and diabetes
  • poor nutrition
  • side effects of a medical treatment, such as chemotherapy
  • stress

What is the science behind it?

Low-level laser therapy (LLLT), aka photobiomodulation, is a noninvasive, pain-free treatment that uses low-intensity light to stimulate biochemical changes in cells, helping repair tissue and reduce inflammation.

One of the most common types of LLLT treatment is the stimulation of hair regrowth in men and women with hereditary hair loss. It’s also commonly used in physical therapy, sports medicine, and chiropractic treatment.

The precise biochemical mechanism underlying the therapeutic effects of LLLT isn’t yet fully known, but it appears to have a wide range of effects at various levels. For instance, within cells, LLLT acts on the mitochondria (the cellular “power plants”) to increase energy. This stimulates regeneration and healing of damaged muscles, ligaments, nerves, bones, joints, and soft tissue. The technique is referred to as “cold” laser therapy because the low levels of light aren’t enough to heat your body’s tissues, so it produces no sensation or burning.

At low doses, LLLT has been shown to increase the proliferation of these types of cells:

  • Fibroblasts, the cells that produce collagen and elastin
  • Keratinocytes, the cells that produce the protein that makes up skin, hair, and nails
  • Endothelial cells, commonly found in blood vessels, lymph vessels, and the heart 
  • Lymphocytes, a type of white blood cell that’s an important part of the immune system

How long until you see results?

The time it takes to see results from LLLT treatment varies depending on the individual and the severity of hair loss. According to a study, patients who underwent LLLT treatment for 24 weeks showed a significant increase in hair density compared to those who received a placebo. However, it is important to note that LLLT is not a quick fix and requires continued commitment to see and maintain results. A series of treatments is usually necessary to see benefits.

More research is needed, but some studies have yielded encouraging results:

According to a 2014 study Trusted Source, low-level laser therapy appeared to be safe and effective for hair growth in both men and women.

A 2013 study Trusted Source of 41 males ages 18 to 48 found that laser hair treatment provided a 39 percent increase in hair growth over a period of 16 weeks.

What are the pros and cons of low-level laser therapy?


The treatment is noninvasive and painless.

LLLT is considered safe and isn’t associated with any side effects. (the most important pro)

A growing body of research shows that it may be effective for a wide variety of conditions and concerns, including hair loss.


Depending on the application, a series of treatments is usually necessary to see benefits. 

LLLT hair loss devices like Xtralux are expensive and require continued commitment to see and maintain results.   The commitment is minimal at 6 minutes a day while the reward is more retained hair, thicker hair in some cases. Yes, results vary from patient to patient but at my practice I have had on person complain and when I did the follow with the patient it turned out that she was not following the directions. I always ensure that my patients understand the level of commitment required before purchasing. I have personally use one daily and have seen first hand the impact it had in my own hair loss. Ah, you thought because I am a hair loss physician, I do not have hair loss? Every non-surgical procedure I offer, I first tried in on myself! There is no better way to feel secure that the procedures you offer actually work!

Some claims for LLLT may be unsubstantiated. More rigorous research is needed to evaluate the effects of LLLT. Because of the inconsistency in studies, this remains a controversial therapy.

How much does low-level laser therapy cost?

Most health insurance carriers consider LLLT experimental and investigational, so be sure to speak to your plan provider before having treatment, to see if any of the costs for your therapy will be covered. They tend to run 3K+ for a hat but the ROI far outweighs the cost. Why? Because the very first thing I ask my hair transplant candidates is: “What are you doing to stop your hair loss?” LLLT is the first line of defense against hair loss. Some patients are about to spend tens of thousands of dollars on hair transplant when they could have avoided it by doing something so easy as LLLT.

The RX version, the one that is medical grade, is only sold in medical offices by doctors, you cannot purchase them at Costco etc. The rest all have LLLT but their potency is lower and the testing mentioned above has been conducted using the RX LLLT, so purchase wisely.
