Does Low-Level Laser Therapy Really Regrow Hair? The Truth Revealed
Hair loss is very unsettling, whether it’s showing up as hairline recession, thinning crown, diffuse shedding, or bald spots/patches. Thankfully, it’s treatable with many hair restoration solutions. One of the non-surgical hair fall treatment in Delhi that has proven itself as a promising treatment option for those seeking hair regrowth is low-level laser therapy.
But most hair loss sufferers ask: Does low-level laser therapy really regrow hair, or is it just a trend?
Yes, many patients can benefit from this approach with proper evaluation and guidance.
Here’s an expert's review of low-level laser therapy for hair growth.
Low-level laser therapy (LLLT) is the most advanced, non-invasive option for hair regeneration, where red light is specifically utilized to create a healthy scalp for hair regrowth and to delay the progression of hair loss.
The light that is focused is of a broader spectrum and so produces low-energy. It cannot generate heat for tissue removal like medical-grade lasers, but it can boost cellular activity within the scalp.
The source of the low-energy light is usually a laser cap, laser helmet, laser comb, or in-clinic laser device.
Currently, this therapy is being used as a part of the comprehensive hair restoration plan by most cosmetic dermatologists in some patients. It showed up decades ago for the treatment of alopecia, and since then, it has been reviewed and upgraded to serve most alopecia patients. Today, it’s considered to be a worthy hair preservation and stimulation tool.
Well, many clinical studies have reported the safety and efficacy of laser combs, helmets, or caps in
regrowing hair in patients with early-stage pattern baldness.
There have been articles showing FDA approval, independent studies on some over-the-counter devices, and many internal studies by the brands that manufacture these devices.
All these studies indicate that these devices are clinically safe and effective for treating hair loss. They make one confident about the technology benefits. But knowing the exact working of these devices can make things clearer.
To understand the benefits of low-level laser therapy for hair, it’s important to understand how low-level laser therapy really works.
Well, the underlying principle of the action of laser combs, helmets, or caps is photo- biomodulation. According to this concept, the red light around 660 nm is absorbed by the specific chromophore present in the hair bulge, which carries stem cells of the hair follicles. This initiates the cascade that supports hair growth.
Here’s what scientists found happening during a low-level laser therapy:
Generally, low-level laser therapy is documented to be most effective for patients with early to moderate pattern baldness and early-stage hair thinning. It has shown improvement in hair density, thickness, and overall hair growth in patients whose hair follicles have not been extensively damaged.
