What Is Laser Hair Treatment?

Laser hair treatment or Low-Level Laser Therapy (LLLT) is an FDA-approved, effective, and safe treatment for male and female pattern hair loss (androgenic alopecia). It is a non-invasive and painless therapy that uses low-level monochromatic red light to stimulate hair growth (1).

How Does Laser Treatment Work For Hair Growth?

The low-level laser irradiates photons into the scalp tissue. These photons get absorbed by the hair follicles, stimulating blood circulation. Increased blood circulation leads to increased nutrient supply to the hair follicles and increased cellular activity. This results in thicker and stronger hair follicles, boosting hair density or the number of hairs on the scalp.

A study by American scientists found that laser treatment for 16 weeks showed 39% hair growth in men between the ages of 18-48 with male pattern baldness (2).

A 2019 review confirms that low-level laser hair therapy is an effective hair loss treatment for men and women (3). Another review supports that low-level laser treatment is a good option for men and women with androgenic alopecia who do not want to undergo surgery or use medical therapy (4).

There are many reasons laser hair therapy is considered good. Find out the benefits in the following section.
