Low level laser therapy hair loss Review: Is it Worth It?

What is Low level laser therapy?

low level laser therapy hair loss reviews

Low level laser therapy is a form of alternative medicine that uses laser light at low levels or near-infrared light. The light is applied to the surface skin of the body with the intentions of decreasing pain or inflammation, promoting healing of wounds, tissues, and nerves, or for preventing tissue damage. This is much different than the high level lasers that we know for surgical procedures to cut and destroy unhealthy tissue.

The lasers used in LLLT are typically small (often handheld) units, and unlike surgical and aesthetic lasers, do not heat the targeted tissue. Instead, LLLT emits low levels of light that are absorbed by your mitochondria (the energy-producing organelles in many of your cells), which then can increase cellular energy production and ultimately help heal surrounding tissue. This process is comparable to plant photosynthesis, during which sunlight is absorbed by plants and converted to energy for the plants to grow.

Low level laser therapy (also called red light therapy, low level light therapy, cold laser, soft laser, biostimulation and photobiomodulation) uses infra-red laser beams to treat a variety of health conditions, one of which is hair loss. LLLT is a painless therapy that requires a minimal time commitment. Studies establish that it decreases inflammation, increases local blood flow and stimulates hair growth. When used correctly, it can be highly effective for hair restoration.

Why Low level laser therapy?

low level laser therapy hair loss reviews

mitochondriaLow Level Laser Therapy (LLLT) has a photochemical effect (like photosynthesis in plants). One of the main mechanisms of action occurs in the mitochondria (the cellular power plant inside every cell). The effect depend on the application of the correct wavelength and density of light, delivered to the target tissues for an appropriate period of time (typically between 30 – 60 seconds). Pulses can improve tissue repair and anti-inflammatory effect, analgesia is best achieved with a continuous beam.

TISSUE REPAIR AND ANTI-INFLAMMATORY EFFECTS

The primary effect occurs when light is absorbed in cytochrome c oxidase a protein within the mitochondria.

When cells get stressed (perhaps due to disease, injury or ageing) the mitochondria produces nitric oxide (NO). This competitively displaces oxygen from cytochrome c oxidase consequently reducing ATP (an essential intracellular cellular energy and extracellular signalling molecule) and causing an over production reactive oxygen species (ROS) and leading to oxidative stress. Oxidative stress is well known to lead to inflammation an cell death via the gene transcription factor NF-Kb.

Low Level Laser Therapy (LLLT) of the correct wavelength and density, dissociates NO allowing oxygen back in, so ATP is restored and oxidative stress reduced. Once normal mitochondrial function is restored by LLLT then cell metabolism is improves, and the patient gets better more quickly.

The effects of LLLT are photochemical(cold), not thermal. During treatment of the tissue with the 635nm laser, an interaction between cells and photons takes place: a photochemical reaction. Photons from the laser affect the tissue at the cellular level. The cold laser enters the tissue, alters cell membrane permeability, and at the cellular level is absorbed in the mitochondria. The mitochondria are the “powerhouse” of cells and make ATP which is needed for the life enhancement process of every cell which facilitates:The effects of LLLT are photochemical(cold), not thermal.

– rapid cell growth. The laser accelerates cellular reproduction and growth.
– faster wound healing. The laser stimulates fibroblast development in the damaged tissue. The reduction in recovery time is an important consideration
– increased metabolic activity. Helps the body increase output of specific enzymes, greater oxygen to blood cells and more effective immune reponse are induced by laser
– reduced fibrous tissue formation. The laser reduces formation of scar tissue following tissue damage from cuts, scratches, burns, or following surgery
– anti-inflammatory action. The laser reduces swelling caused by bruising or inflammtion of joints to give improved joint mobility.
– increased vascular activity. The laser stimulates lymph and blood circulation, to allow the affected tissue to have the best possible circulation
– stimulate nerve function. Slow recovery of nerve function in damaged tissue can result in “dead” limb or numb areas. Laser will speed the process of nerve cell reconnection to bring the numb area back to life. Laser also increases the amplitude of action potentials to optimize muscle action.

Low level laser therapy hair loss Review

Where do I begin? Low Level Laser Therapy for hair loss, or “LLLT” for short, has been around for a long time. The first ever mention of low level laser therapy having a positive effect on hair growth was in 1967. A Hungarian scientist named Dr. Endre Mester was using the new laser technology to see if it would cause cancer in mice. I say “new” because lasers were only invented seven years earlier in 1960. During his experiment he shaved some mice so that the laser could better penetrate their skin (this wasn’t a cutting laser) and while he learned that low level laser light doesn’t cause cancer he also noted that the areas where the mice were “hit” with the laser seemed grow more hair. Is this conclusive evidence that low level laser therapy for hair loss works? Of course not, because the mice didn’t have any sort of genetically programmed hair loss, natural or manmade, and they were essentially just normal average mice with their fur shaved off so it kind of doesn’t make sense, unless there is more to the story, but it is the first documented observation of this phenomenon. Personally, I don’t think we can rule out that he was just shooting lasers as these mice like any ten year old kid would as soon as he got his hands on a new laser toy, like kids do with magnifying glasses on sunny days:) This observation was made a full forty years BEFORE the first FDA cleared laser device for hair loss hit the market. This means that the technology behind laser hair restoration systems isn’t anything new and in fact it is quite old in the overall scheme of things, not to mention it is fairly primitive.

What Type of Hair Loss Does LLLT Treat?-LLLT treats androgenetic alopecia, which is more commonly referred to as male or female-pattern baldness.  Androgenetic alopecia is a genetic condition and it is the most common cause of hair loss in both men and women. It affects 50% of males over the age of 40, and 75% of females over 65. People with androgenetic alopecia have a gene that makes them more sensitive to the effects of the androgenic hormone—Dihydrotestosterone (DHT). DHT can build-up in the inner roots of the hair follicles and, in genetically-sensitive individuals, the DHT causes the hair follicles to get smaller and smaller. Eventually the follicles become completely dormant and hair growth stops completely.
