Overview

​

Every day, most people lose about 100 hairs from their scalp. Some people don't grow those hairs grow back due to:

• age

• heredity

• hormonal changes

• medical conditions, such as lupus and diabetes

• poor nutrition

• side effects of a medical treatment, such as chemotherapy

• stress

​

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.

​

The Theory

​

The theory of laser treatment for hair loss is that the low-dose laser treatments invigorate circulation and stimulation that encourages hair follicles to grow hair.

​

Studies have yielded encouraging results

​

• According to a 2014 studyTrusted Source, low-level laser therapy appeared to be safe and effective for hair growth in both men and women.

• A 2013 studyTrusted Source of 41 males ages 18 to 48 found that laser hair treatment provided a 39 percent increase in hair growth over a period of 16 weeks.
