What Results Does Low Level Laser Therapy for Hair (LLLT) Produce?

Low-Level Laser Therapy for hair LLLT (or LPT) is a proven hair loss 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 promotes wound healing and reduces inflammation. It works through the photo-stimulation 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.
