What Is Red Light Therapy for Hair Growth?

Red light therapy, also referred to as low-level laser therapy (LLLT), uses specific wavelengths of light, typically in the red to near-infrared spectrum, to penetrate the scalp and stimulate hair follicles. 

It works on the concept of photobiomodulation, where light energy is absorbed by cellular mitochondria, leading to enhanced cellular energy production and improved function.

The wavelengths used in red light therapy usually range from 630 to 670 nanometers. Thanks to their bio-stimulating effects, they help increase blood circulation and oxygen supply to the scalp, creating an optimal environment for hair growth.

Clinical studies have supported the effectiveness of red light therapy in promoting hair growth, and its regular use can lead to a significant increase in hair density. It is also praised for being non-invasive, pain-free and devoid of serious side effects.

The key to achieving the most satisfying results is using the best red light therapy for hair growth. Here’s the list of recommendations for you!
