As people seek natural solutions to hair loss problems, the popularity of red light therapy has soared. While previously only available at medical spas and clinics, this non-invasive hair loss treatment has become more accessible thanks to portable devices allowing at-home use.
In case you’re unfamiliar, red light therapy utilizes low levels of laser and infrared light to penetrate the scalp and encourage the growth of new, healthy cells. Additionally, it can boost blood circulation and oxygen supply to the scalp, resulting in faster hair growth.
This article will examine the five best red light therapy for hair growth in 2023.
Red Light Therapy and Hair Growth
Red light therapy, also called photobiomodulation or low-level laser therapy (LLLT), has become increasingly popular in the beauty industry due to its proven effectiveness in promoting hair growth.
Recent scientific studies demonstrate that red light therapy penetrates the scalp using energy from visible red light and invisible near-infrared wavelengths of light. This treatment enhances blood flow and stimulates the creation of ATP, which is crucial for cellular functions and hair development.
Additionally, it elevates cell metabolism and encourages collagen production, strengthening hair follicles and reducing inflammation. Red light therapy is a risk-free and non-intrusive method with proven efficacy in treating various hair-related ailments, such as alopecia, thinning hair, and male pattern baldness, without any negative side effects.
Studies on Red Light Therapy and Hair Growth
While some evidence suggests that RLT may be effective for hair loss, the optimal treatment protocol is still being investigated. Here are some key findings from recent research:
The best wavelengths for red light therapy for hair loss
The wavelength used in red light therapy is an important factor in determining its effectiveness, as different wavelengths of light have different effects on the body. Red light therapy typically uses light in the range of 630-670 nm.
However, the optimum wavelength for red light therapy is still debated and researched.
Many studies on red light therapy have used light sources in the 655nm ± 20nm range, close to the middle of the red light spectrum. This wavelength range effectively promotes cellular activity, and reduces inflammation.
Effective Power Density
The power density, or strength, of the RLT, also is important. A study published in the Journal of Cosmetics found that power density above 50 mW/cm2 was more effective at stimulating hair growth than lower power densities.
Treatment Duration
The duration of RLT treatment sessions also plays a role in their effectiveness. A study published in the journal Lasers in Medical Science found that a 25-minute daily session of RLT over 16 weeks led to significant improvements in hair density and thickness compared to a control group. The general recommendation is that each session should last anywhere from 15 to 30 minutes, with multiple weekly sessions.
