Laser Therapy

Low-Level Laser Light (LLLT)

Low-Level Laser Light is one of the most effective therapies to treat hair loss. Currently, over-the-counter laser therapy devices for hair growth are available through convenient hands-free systems, or less convenient hand-held devices. Either product may be used at home, and does not require the supervision of a physician.

LLLT Defined

The laser light used in promoting hair growth is defined as Low-Level Laser Therapy (LLLT). LLLT is sometimes included under a broader definition of ‘Phototherapy’ called Low-Level Light Therapy, where the light-emitting device may be a laser and/or light-emitting diode (LED).

LLLT at Work

It is theorized that when the laser light is absorbed by target tissue molecules, the energy level of the molecules is increased and the molecules respond by ‘working off’ the excess energy with adaptive changes. These changes may be chemical or physical, and they may have biological effects on the target tissue or surrounding tissues.

Treatment of Androgenetic Hair Loss

It is hypothesized that LLLT initiates the chemical reaction in the cells that make up the follicle’s epithelial matrix causing the proliferative activity.

Much evidence points out that follicular apoptosis (programmed cell death) is reversed via the application of laser energy. Observations of wavelength stimulation of optimal hair growth, has shown precisely what wavelengths, power, and intensity are necessary for optimal effect in stimulating new hair growth.

It is important to note that heat is not associated with the photochemical and photo therapeutic effects of LLLT. LLLT is a low wattage ‘cold light’ laser, and while there are visible red wavelengths, there is no sensation on the skin of persons undergoing treatment. Cold lasers are safe and universally accepted as such by medical authorities, worldwide. Also significant is the fact that there are no side-effects associated with the use of LLLT, as there are with usage of pharmaceuticals, topicals and pills.

Who May Benefit from LLLT?

Medical experts who specialize in treating hair loss agree that treatment should be based on the correct diagnosis of its cause.

Hair loss physicians and medical experts agree that LLLT is a highly viable option for growing hair in those afflicted with androgenetic alopecia-inherited/genetic pattern hair loss. It is not intended to treat hair loss due to other factors.

In treating androgenetic alopecia with LLLT, physicians have found that LLLT is most effective in persons with minimal to moderate hair loss. Individual responses to LLLT differ, and results do vary from person to person.

Is LLLT Effective in Hair Restoration?

The vast majority of physicians and medical experts agree that LLLT can be effective in growing hair in those with genetic pattern hair loss. Experts have also observed and noted that the overall health and condition of hair may be improved in a LLLT treated area.
