In 1966, Hungarian physician Endre Mester first published an experiment in which he observed accelerated hair growth in rats treated with laser therapy, making alopecia the first legitimate therapeutic indication for laser therapy. Recently LLLT (low-level laser treatment) has gained acceptance in treating hair loss as evidence from clinical trials and successful patient cases have validated the therapy.
Though it has been used for over a decade… in the last few years, low-level light therapy has finally gained mass acceptance by the foremost physicians in the field of hair restoration, including world-renowned physicians who are both leaders and members of prestigious industry organizations such as the American Board of Hair Restoration Surgery and the International Society of Hair Restoration Surgery.
Low-level light therapy (LLLT) has been used since the 1960s to treat various medical conditions such as alopecia, chronic ulcers, and chronic pain, headaches, musculoskeletal, and neuropathic pain without major adverse side effects. Each of these applications is based on the biological effects of photobiomodulation in living organisms. The use of low levels of visible or near-infrared (NIR) light for reducing pain, inflammation and edema, promoting healing of wounds, deeper tissues and nerves, and preventing tissue damage has been known for almost forty years since the invention of lasers1.
A multitude of fields of medicine have applied the science of phototherapy using low-power laser to their professions:
- Physical therapists: to treat a wide variety of acute and chronic musculoskeletal aches and pains
- Dentists: to treat inflamed oral tissues and to heal diverse ulcerations
- Dermatologists: to treat edema, non-healing ulcers, burns, and dermatitis
- Orthopedists: to relieve pain and treat chronic inflammations and autoimmune diseases
- Veterinary Medicine
- Sports Medicine and Rehabilitation Clinics: to reduce swelling and hematoma, relieve pain, improve mobility, and treat acute soft-tissue injuries.
