There is an exciting new option in hair restoration that is painless and noninvasive – Laser Hair Therapy. Low level laser therapy (LLLT) is a non-chemical, non-invasive treatment that is being used around the U.S. for the treatment of hair loss.
How does Low Level Laser Therapy (LLLT) Work?
Lasers have long been used in all types of medical specialties, including dermatology. Many have used specific lasers to resurface the skin by creating a wound on the top layer so that new, fresh skin emerges from underneath. But a new generation of lasers takes a very different—‘wound-less’—approach. To understand how LLLT works, you have to alter the way you view lasers. LLLT isn’t a light source that causes thermal, or heat, damage. With LLLT, there is no cutting or burning sensation. The technology doesn’t even resemble the look of traditional lasers. Instead, LLLT is delivered by a device that contains panels of lasers that shine on the scalp. Laser hair therapy uses a laser diode operating in the red portion of the visible color spectrum. Laser energy is different from natural light in several ways. It is monochromatic, which means all the energy is essentially one wavelength or color whereas a light bulb produces a broad spectrum of light and energy waves. Laser energy is also collimated which means it is a tight beam of light energy that spreads or diverges only a little at great distances while a light bulb loses its brightness very quickly with distance.
The relationship between lasers and hair growth was first discovered almost 40 years ago. During the 1960’s and 1970’s, researchers used low level lasers to evaluate their potential bio-stimulating effects on living tissues. In a surprise finding, during experiments on patients with leg ulcers, doctors observed that the hair follicles which surrounded the area being treated by the low level laser grew new hair.
Laser light appears to stimulate microcirculation, decrease inflammation and improve both cellular metabolism and protein synthesis. Furthermore, European studies suggest that LLLT increases blood and lymph circulation at the hair roots and stimulates follicular cells, which may cause hair to grow thicker and stronger. Living cells thrive in light and your head is no different.
Professional Laser Hair Restoration Products for Women and Men
In January of 2007 a hand-held laser therapy device, called the HairMax LaserComb, was cleared by the FDA as a treatment for ‘androgenetic alopecia’ (male pattern hair loss). The way the laser comb works is quite simple. The visible red light from the comb’s lasers travel several layers into the tissue without harming the skin and scalp. Because the laser light does not cut or burn the skin, the therapeutic light-energy is absorbed by the cells and the process of cell repair begins. One theory of how this noninvasive, non-chemical hair loss treatment works is that it stimulates the production of energy at the cellular level; therefore, improving cell function.
Professional hair laser products are now available for personal use. They come in a wide array of sizes and price points. All LLLT lasers that are used to treat hair loss have these same specifications: 5 milliwatts of Power and 650 nanometers of wavelength.
The Super Grow 50 is a smaller version of the clinical models used in laser hair salons. It contains 50 full strength lasers in a convenient overhead delivery system. All you have to do is sit in a chair and turn it on.
If 50 lasers are not enough and you’re looking for more of a complete salon experience then the Super Grow Dome 90 is what you need. Dome hoods are the standard method of laser delivery in the professional salons. This allows the lasers to be aimed at the scalp at a 90 degree angle from all sides. With 90 lasers and a fully adjustable stand you can’t go wrong.
If you travel much a portable model is available, the Super Grow Handheld Travel Laser. It contains 12 full power lasers in a compact design.
Another product that utilizes phototherapy to regrow hair is the Plasma Ion & Photo Therapy Hair Growth and Repair Brush. Unlike the laser models above, it uses LED light for photo rejuvenation, which stimulates metabolism and supports healthy hair growth. This device also purifies your hair and head with ozone. Electronic ions discharge and sterilize your scalp while the 3-D Micro Massage accelerates blood circulation by vibrating 6000 times per minute.
Do Laser Combs Regrow Hair?
Men and women of all ages who have used hand held low level laser hair therapy devices have said their hair looks and feels thicker, fuller, healthier, and have noticed improved hair growth. Like other treatments some folks tend to respond better than others. In general, men and women who have “more hair” tend to receive better results. A study published in the International Journal of Cosmetic Surgery and Aesthetic Dermatology, (Vol. 5, Number 2, 2003 by John L. Satino and Michael Markou, D.O.), titled “Hair Regrowth and Low Level Laser Therapy” concluded “LLLT with the HairMax LaserComb is an effective treatment for stimulating hair growth and increasing the tensile strength of hair in both sexes in both the temporal and vertex regions.” At the 2005 Annual meeting of the American Society for Laser Medicine and Surgery a preliminary report was presented on the positive effects of Phototherapy on the hair follicle, including hair growth. This preliminary study also provided some insight into the mechanism of action of phototherapy and its effect on the cells of the hair follicle.
Low Level Lasers have been approved in this country as a treatment for carpal tunnel syndrome, as a wound-healing aide, and as an adjunct to liposuction procedures. Laser therapy has been safely used for decades throughout Europe, the Far East and has no documented side effects.
