Low-level light therapy (LLLT) using red or near infrared light is scientifically proven to treat genetic forms of hair loss (androgenetic alopecia). Red light therapy has been shown to cause hair to regrow the crown area and along the hairline, the most common places that men tend to lose their hair.
Does infrared light promote hair growth?
One, by accessing the mitochondria and stimulating fast hair cell repair and growth. Two, by promoting blood flow and circulation to the scalp and hair follicles which strengthens hair. … Red light therapy for hair growth also has no side effects, is minimally invasive and completely safe and painless.
What does infrared do to your hair?
“Infrared helps to dry the hair from the inside out,” she tells me. “This allows you to use less heat, and by minimizing the exposure to heat, you alleviate styling stress on the cuticle.
How does red light therapy work on hair growth?
Low-level laser therapy — also referred to as red light therapy and cold laser therapy — irradiates photons into scalp tissues. These photons are absorbed by weak cells to encourage hair growth. It’s widely accepted that the procedure is safe, tolerable, and less invasive than hair transplant surgery.
What kind of light stimulates hair growth?
Improve Circulation, Stimulate Growth
Red light is particularly interesting when it comes to hair and scalp health – just as it speeds up healing, it also prompts the body to grow hair faster. Red light therapy “increases circulation and stimulates new growth, leading to better scalp health overall,” notes Joanna.
Does light therapy work for thinning hair?
You may have heard that laser combs, brushes, hoods, and caps can help halt hair loss. The theory is that when hair follicles absorb laser light at a certain level, it stimulates hair to grow. But there’s not enough evidence that any of these devices restore hair or prevent balding.
Does infrared heat dry hair faster?
Conventional dryers use longer wavelengths and directly dry the surface of the hair, while infrared heat warms objects from the inside out. Negative ions present in the heating process break up water molecules present in the hair, leading to quicker dry and less damage.
Is infrared heat safe for hair?
Unlike traditional flat irons that can fry your hair, infrared straighteners use gentler heat that deeply penetrates hair and uses negative ions to lock in moisturize. The result is less damaged, less frizzy hair. To learn more about infrared flat irons, read our shopping guide.
