Low-Level Laser Therapy (LLLT), also known as laser hair therapy or red light therapy, is a non-invasive treatment that uses specific wavelengths of light to stimulate hair follicles and promote hair regrowth. LLLT has been FDA-cleared for the treatment of hair loss, and it is considered a safe and effective solution for both men and women.
How Does LLLT Work?
LLLT uses red light (typically around 650–900 nanometers in wavelength) to stimulate the mitochondria of hair follicles, improving cellular activity and promoting healthy hair growth. The light penetrates the scalp, encouraging blood circulation and increasing the production of ATP (adenosine triphosphate), which provides energy to the cells. This increased cellular energy helps to revitalize hair follicles, leading to thicker, fuller hair.
The Benefits of LLLT for Hair Restoration:
- Stimulates Hair Follicles: LLLT increases the blood flow to the scalp and energizes hair follicles, improving hair thickness and density.
- Non-Invasive and Painless: The treatment is completely painless, non-surgical, and requires no recovery time. Patients can relax during the treatment, which typically lasts about 20–30 minutes.
- FDA-Cleared: LLLT is FDA-approved for hair regrowth, providing reassurance to patients about the safety and effectiveness of the treatment.
- Convenient: LLLT can be done in-clinic or at home with devices such as laser combs, helmets, or caps, making it easy to incorporate into your daily routine.
What to Expect from LLLT:
- Procedure Duration: Each session typically lasts between 20 and 30 minutes.
- Frequency: To see results, patients are usually advised to undergo LLLT treatments 2–3 times a week.
- Results Timeline: It may take several months of regular treatment before visible results begin to appear, with optimal results seen after 4–6 months of consistent use.
