What is the origin of low level laser therapy?

What is the origin of low level laser therapy? Who really invented laser therapy?  In 1965, Hungarian Physician Dr. Endre Mester was testing the effects of lasers on mice. To allow for easier penetration, he shaved the mice’s hair. He soon noticed that hair on mice grew back much quicker than mice unexposed to laser light. Curious, Dr. Mester soon discovered that his assistant had accidentally turned the laser power down to a very low capacity. This emitted a cold or “low-level” laser. Today, Dr. Mester is recognized as the father of Low-Level Light Therapy, otherwise called Laser Phototherapy.

What results does low level laser therapy for hair (LLLT) produce?

Low Level Laser Therapy for hair LLLT (or LPT) is a proven hair los solution. Through multiple clinical trials, is has been shown to achieve the following:

  • Reduce or prevent hair loss
  • Return weak, vellus hair to a natural, healthy terminal hair state
  • Increase the thickness of hair
  • Promote new hair growth

All of these factors can contribute to a fuller, thicker and more vibrant head of hair.  Low Level Laser Therapy for hair was first developed in 1967. LLLT promots wound healing and reduces inflammation. It works through the photostimulation of cells involved in the human body’s repair process. Unlike industrial lasers that use high heat, low-level laser light, which comprises cool or cold lasers, does not cut, burn or otherwise damage human tissue. And unlike common light bulbs or LED lights, laser light does not disperse. The ability to concentrate cold laser light within a small diameter allows the light to focus its energy on a specific target.

There are three very important aspects of low level laser therapy for hair to consider – wavelength, dosage, and delivery.

Wavelength: The higher the wavelength (red light) the deeper the penetration. This means that at around 680nm (what Theradome uses) vs 650nm (what other companies use), we can get much deeper and more effectively stimulate hair follicles. This provides better low level laser therapy results.

Dosage: Our dosage schedule requires just two 20-minute sessions per week. This is because our lasers deliver extremely targeted wavelengths that produce no heat. Other devices on the market tend to run warm to hot. This requires them to reduce laser output so you’re not receiving the full benefits of treatments.

Delivery: Our proprietary 680 nanometer lasers made in the US provide targeted wavelengths delivered with low divergences beams for maximum scalp penetration. This is unlike other products with high divergent beams. They do not travel deep enough to penetrate the scalp to receive low level laser therapy results.

What are the Theradome’s 680 nanometer laser specifications?

Theradome’s VL680 lasers each have an output of 5 mw. Each laser illuminates the scalp with a light intensity of 7 J/cm2. This is sufficient to penetrate 3 to 5 mm into the scalp to the base of the hair follicles. Scalp coverage is measures 582 square centimetres.

The VL680 laser is the only laser on the market that delivers the optimal wavelength for the deepest penetration to the hair follicle.
