How to Use a Laser Comb to Promote Hair Regrowth

Last Updated on December 12, 2022 by Gaga

What Is Laser Comb?

A laser comb is a handheld, battery-powered device equipped with laser diodes and is intended to treat hereditary types of hair loss. Laser comb devices use low-level laser therapy technology to stimulate hair follicles to help grow denser and thicker hair. A laser comb’s efficiency is greatly determined by the number of laser diodes it has.

Since the FDA approved a laser hair-growth device for home use in 2007, similar devices have flooded the market. These appliances are intended for people who prefer the convenience of home treatments. Now people can improve the condition of their thinning hair in the comfort of their own homes, getting the treatment at a fraction of the cost they would pay in a hair replacement salon.

How Do Laser Combs Work?

Low-level laser therapy (LLLT)—also known as photobiomodulation, or cold laser therapy—uses low-power lasers to relieve pain, stimulate cells, and heal body tissues.

Multiple studies suggest that cold laser therapy has a positive effect on hair regrowth in both sexes. LLLT delivers light at the ideal wavelength of 680 nm, allowing the treatment to penetrate deep into the scalp to reach the hair follicles.

LLLT stimulates cellular processes to rejuvenate inactive cells within hair follicles. Exposure to laser diodes increases blood flow to the hair roots, providing the nutrition that hair needs to grow.

LLLT puts the follicles into the active growth phase and increases their ability to produce new hair.

By stimulating follicles in this way, LLLT can slow and reverse the process of follicle miniaturization responsible for most cases of hair loss. Revitalized hair follicles work better, resulting in less hair fall and a stronger and thicker head of hair.

Just as plants need light to grow, your hair might need LLLT to grow denser.

A laser comb has fewer laser diodes than hand-free types of laser devices. However, it has teeth that separate the hair that can block the laser light. This allows the light to shine on the scalp, ensuring better penetration and greater effectiveness.

Who Is the Ideal Candidate for Using Laser Hair Comb?

  • The ideal candidate for LLLT is someone who has just started to lose hair because of genetics and wants to prevent further hair follicle miniaturization. If your hair is in the process of thinning, the follicles are still alive, so a laser comb may be beneficial to you. A laser comb can reactivate follicles that still grow small, thin hairs and stimulate them to produce stronger hair.
  • This device is intended for individuals who are willing to commit and adhere to the instructions religiously.
  • Laser devices for hair growth are not intended for people whose follicles haven’t generated new hair for years. Once a hair follicle has died, it can’t be reanimated. Therefore, if you are noticing any hair loss, it is recommended you start the treatment as early as possible to maximize the potential for optimal results.
  • A laser comb is not for individuals who can’t commit to using it consistently or looking for a miracle treatment and an overnight cure.

How to Use Laser Comb to Stimulate Hair Growth?

A laser comb operates by moving it across the scalp for the instructed length of time. The treatment duration varies for different devices. In general, laser combs with more light-emitting diodes offer shorter treatment times.

The treatment is performed once per day, or two or three times per week, for the recommended length of time, which is usually 10 to 20 minutes. Using the device more frequently or longer than recommended does not add any benefit. However, you can combine the use of a laser comb with other treatment options such as Rogaine, Minoxidil, Propecia, supplements, hair growth serum, and hair growth shampoo.

During the first two months, you may notice increased shedding of fine hairs. This is perfectly normal, so you should just keep going. Each hair strand passes through the four-stage hair growth cycle, and the baby thin hairs must fall out to be replaced by stronger ones.

To obtain optimal effects, regular, continued use is essential. Soft laser therapy alters the hair growth cycle, prolonging the active growth phase. Since hair grows slowly, laser hair restoration is a slow process that needs commitment and patience. 

If the device is used regularly, the first noticeable progress can be identified within 3 to 6 months, while maximum results can be obtained within a year.

If you see signs of improvement, you must continue the treatment to maintain results. If you stop using the device, the hair will continue to fall out, since hereditary hair loss is a progressive condition. When it comes to laser combs, consistency is the key to achieving and maintaining healthier, thicker hair.
