Everyone loses around 50 to 100 strands of hair per day which are replenished by new hair growth. However, if your ability for new hair growth is compromised, you may want to use a laser hair growth device.

There are many reasons for losing hair. They can range from aging, hereditary reasons called alopecia, medical conditions, and side-effects of medical treatment like cancer treatment as well as lifestyle elements like stress and improper diet.

In most of these conditions, the low-level laser may be useful in reinvigorating your scalp and reinstate new hair growth or at least stem the loss of hair.

When compared to other means of treatment, cosmetic or otherwise, laser hair treatment is beneficial in the sense it permanently increases your hair growth, reduces hair fall, leading to better hair density.

It does not lead to irritation or scratching or pain in the scalp, does not require any invasive procedures and you can complete it from the comfort of your home.

How Does a Laser Hair Growth Device Work?

Low-Level Laser (Light) Therapy (LLLT) is effective against hair loss for both men and women1. LLLT uses a medical-grade laser to increase circulation in your hair follicles.

In this technology, basically, the hair follicles absorb the light energy, which in turn energizes the microcapillaries under the follicles, leading to the enhanced blood supply to the follicles and the scalp.

This allows the increased supply of nutrients to the hair root, strengthening the base of the hair, which subsequently leads to stronger and healthier hair strands.

What to Look for in a Laser Hair Growth Device?

  • Ease of Use: As this device is to be used daily or at least 3 times a week for an extended period of time, if it is not convenient to use, it will be difficult for you to continue to use it as a ritual. Some laser hair growth devices are just to be worn as a cap or a helmet and they are more convenient and hands-free than laser bands or laser combs
  • FDA Clearance: The safety clearance is important to note as too strong a laser will not be good for your health. FDA clearance can lead you to use the product with peace of mind.
