Low-Level Laser Therapy(LLLT)
LLLT (Low Level Laser Therapy)
Low-level laser therapy — also referred to as red light therapy and cold laser therapy — irradiates photons into scalp tissues. These photons are absorbed by weak cells to encourage hair growth. It’s widely accepted that the procedure is safe, tolerable, and less invasive than hair transplant surgery.
Low-Level Lasers for Hair Restoration
Here are four more benefits of laser hair growth therapy:
1. It’s both safe and effective
The National Institutes of Health’s studies have shown that low-level laser therapy stimulated hair growth in mice subjected to chemotherapy-induced alopecia and also in alopecia areata. “After the discovery of lasers in the 1960s, there has been tremendous interest in using these laser devices to treat various medical conditions,” the NIH reports, noting that controlled clinical trials demonstrated that LLLT stimulated hair growth in both men and women. In conclusion, NIH says that LLLT for hair growth in both men and women appears to be both safe and effective.
2. The medical community has been using cold laser for decades
According to the International Society of Hair Restoration Surgery, the use of lasers for medical purposes is not new. Lasers have been in use for medical purposes for many years and the physics, chemistry, and biology of laser light interaction with human tissue are well documented, the ISHRS reports. Medical uses range from surgery using high-powered lasers to stimulation of tissue repair.
3. There are no scalpels, cutting, or burning
Let’s face it, no one wants to go under the knife if he or she doesn’t have to. With LLLT, the lasers used for hair growth therapy are referred to as “cold” because their light is absorbed by target tissue but does not heat the target tissue as occurs with lasers used to cut and remodel tissue. The light wavelength emitted from a low-level laser will repair tissues that have impaired cellular metabolism by stimulating blood circulation, encouraging regeneration of normal healthy tissues, and encouraging bio stimulatory effect on the hair follicle. LLLT is not a light source that causes thermal or heat damage, there is no cutting or burning sensation at all.
4. It’s already been proven to increase hair density
People have been using lasers as a hair removal method for years, but up until recently the long-term impact on the individual hair follicles was unknown. Recently, the NIH found an uncommon but striking adverse effect of lasers being used for hair removal: an increase in hair density, color, or coarseness or a combination of these occurs at or around sites treated for hair removal. This bodes well for uses of low-level lasers for hair growth!
