Light emitting diode treatment is also known as LED therapy for skin, which uses different waves of blue and red lights. When you opt for this therapy, the healthcare professional will use varying wavelengths of red and blue lights on the skin, where they will use red for the signs of aging the blue for acne treatment.
lllt hair treatment, on the other hand, produce coherent and monochromatic light, which is a wavelength of a single color, and the light waves have phases. A single wavelength makes the medical treatment ideal for hair therapy, this is because the tissue responds to some wavelengths of light. The coherence of the laser light keeps the energy focused and the narrow beam. This way it can perfectly penetrate the scalp and reach the hair follicles.
Wavelength: LED VS Laser
Laser has a wavelength of 680 nm, which stimulates the hair follicles, and lllt hair treatment offers light at one particular wavelength, which can be targeted for this wavelength.
On the other hand, LED light therapy does not use monochromatic light and doesn’t target a specific wavelength, and the beam does not reach the hair follicle. This makes the therapy almost useless when it comes to restoring hair.
Power: LED VS Laser
The final thing to think about here is the power. To effectively stimulate the hair follicles, you need enough power to reach them to create a photo bio-modulation effect. In addition, light becomes gets distributed when it reaches far levels, you need a specific amount of power for the light to get a strong effect that can reach the hair follicle cells. With increased energy, you will get a better result in a shorter time. Low-level laser therapy offers more power than LED treatment. LED therapy is not powerful enough t offer a therapeutic effect when it comes to hair restoration.
Besides, low-level laser therapy can provide one hundred and fifty times more joules than LED therapy, which offers deep penetration at a wavelength of 680 nm.
So, you need to opt for only low-level laser hair therapy when you are looking for hair re-growth. Although a bit expensive, you will get a permanent hair solution.
