How Does Low-Level Laser Therapy Combat Hair Loss? March 4, 2019

How Does Low-Level Laser Therapy Combat Hair Loss?, Rochester, New York

Hair loss is common and natural – but that doesn’t mean you have to let it happen. Thanks to advancements in laser technology, you can combat thinning or shedding hair without surgical hair transplants or other invasive tactics. With low-level laser therapy (LLLT), both men and women can restore thick, healthy locks. Here’s what you should know about this innovative and effective treatment. 

How LLLT Helps With Hair Loss

What LLLT Is 

LLLT has its origins in the late 1960s, when a scientist discovered that directing low laser light over shaven mice stimulated hair regrowth. The therapy works by applying low-heat lasers to the area affected by hair loss. Research indicates that low-level laser therapy is both safe and effective at treating male and female pattern hair loss. Although proven to produce results, scientists have yet to determine precisely how LLLT works. There are, however, multiple prominent theories about how LLLT affects the body at the molecular, cellular, and tissular levels.

What Researchers Have Found

When your cells have plenty of ATP, the life of existing follicles will be extended, halting hair loss. This will also induce the anagen phase – the first stage of hair growth – promoting rapid restoration.  

Another theory suggests that even the safe, low temperatures of LLLT are enough to induce heat shock, boosting the level of heat shock proteins – a family of molecules that form in response to trauma or other stressful conditions. These proteins are associated with healing and tissue remodeling, and may encourage follicular stem cell differentiation and rejuvenation. 

A third possibility is that LLLT inhibits 5-alpha-reductase, an enzyme that helps transform testosterone into a stronger hormone closely linked to baldness called dihydrotestosterone (DHT).

What Results LLLT Delivers

Those with male or female pattern hair loss can expect positive results from low-level laser therapy. Studies have shown that individuals with autoimmune diseases like alopecia are also likely to experience hair regrowth with LLLT. Although the actual results will vary from person to person, most patients will see a noticeable change within two to four months of starting treatment, as long as they attend regular sessions.
