How Does PhotoRejuvenation Therapy Work?
Research has shown that exposing the scalp to red light increases blood flow. Improved microcirculation is thought to increase the flow of nutrients to the hair root or bulb; thus reinvigorating it, kind of like giving water and plant food to a drooping flower.  Direct stimulation of hair producing cells have also been reported.  More recent research with LEDs indicated an effect similar to minoxidil.

What kind of results can I expect?
Doctors have reported that 85% to 90% of the people treated with PBM are satisfied in general. More than half feel there hair looks thicker and fuller.

Will I feel anything?
You will not feel the light; however, depending on the system, you may feel either a little warmth from the electronics or moving air. 

Are there any side effects?
No. There are no known adverse side effects.

Does Hair PhotoRejuvenation work for everyone?
People treated properly with various systems report very high levels of satisfaction.  They believe their hair looks thicker and fuller.  Many said the hair shaft becomes thicker, more elastic and stronger.  However, the effect varies based on how long hair thinning has occurred.  Hair that has been dormant for years generally does not respond as well as hair that has recently become dormant.  Beginning sooner is better.

When will I see results?
In most cases, people see notable improvements in four to six months.  In cases of rapidly thinning hair, a change may be noticed sooner.  Several reports have indicated that patients see an improvement in three to eight weeks with more than half saying their hair looks and feels thicker after six weeks to six months.

When should I start treating my thinning hair?
Sooner is better.  Hair follicles that have been inactive for a long period of time are seldom reactivated.  Starting sooner will rekindle more follicles.  It keeps the flow of blood and nutrients moving to follicles that are starting to enter miniaturization, delaying or reversing their decline and loss. 

What else is Hair PhotRejuvenation called?
People refer to it as Low Level Laser Therapy (LLLT), Low Intensity Light Therapy (LILT), laser hair restoration, cold laser therapy and Luce hair treatments. 

Do LEDs work as well as lasers?
Low Intensity Light Therapy started in Europe with the invention of lasers in the 1960's.  Much of the best work has been done in Russia.  Dr. Tina Kuru and another Russian researcher have published separate studies that demonstrate incoherent light (LEDs) to work as well as coherent laser light (laser diodes).  This happens because laser light loses its coherency almost immediately upon hitting tissue.  The consensus is that incoherent LED light works as well in superficial applications as coherent laser light but that laser is better in deep tissue applications.  This may be result from light speckles in a laser diode beam or "hot spots" with photons concentrated enough that they produce a mild thermal effect.
