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.

The initial laser created to eliminate hair follicles was invented by Theodore H. Maiman on July 7, 1960.

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).

A study conducted on 910 patients suffering from androgenetic alopecia (AGA) analyzed if low-level laser therapy (LLLT) would help improve their condition. The therapy continued for 38 weeks for those with mild AGA (455) and 40 weeks for those with moderate to severe AGA (455). After completion of the therapy, 51.9% of the former and 57.4% of the latter had moderate effect while 27.7% with mild AGA and 20% with moderate to severe AGA had significant effect.

Steven, a YouTuber, shared his experience of using low-level laser therapy. His hair was shedding rapidly and he shaved his head. After using the therapy for 18 months, the hair follicles grew back. He said in his video, “When I first started losing my hair, I was shedding a lot. Once I started using low-level laser therapy that seemed to slow down considerably (i).”

Frequently Asked Questions

Yes. The hair growth after laser therapy is permanent as long as the hair follicle is healthy.

How long does laser therapy take to grow hair?

Small-scale studies of low-level laser therapy have shown positive hair-growth results within 4-6 months.

Which type of laser hair removal is best?

The best type of laser hair removal depends on individual factors such as skin type and hair color.

What should be the gap between laser sessions?
