What is Laser Therapy?
Laser Therapy, also known as Low-Level Laser Therapy (LLLT), is a non-surgical treatment that uses red light wavelengths to stimulate cellular activity. It's commonly used for various medical conditions, including promoting hair growth.
How Does Laser Therapy Work for Hair Growth?
The therapy works by increasing blood flow to the scalp and stimulating metabolism in catagen or telogen follicles, resulting in the production of anagen hair. This means it can help hair that's in the dormant phase to grow.
Types of Laser Therapy for Hair Growth
Low-Level Laser Therapy (LLLT)
LLLT uses cold lasers to deliver light to the scalp. These lasers are low powered and do not produce heat, making them safe and painless.
Laser Caps and Helmets
These are wearable devices that emit laser light directly to the scalp. They're convenient for home use and offer consistent treatment.
Benefits of Laser Therapy for Hair Growth
Stimulates Hair Follicles
Laser Therapy increases cellular activity and blood flow to the scalp, which can stimulate dormant hair follicles.
Promotes Thicker and Fuller Hair
Users often report improved hair thickness and overall hair health after consistent use of laser therapy devices.

A study published in the American Journal of Clinical Dermatology found that laser therapy increased hair density in 85% of participants.
