What Is Red Light Therapy for Hair?

Red light therapy uses specific wavelengths (typically 630–670 nm and 810–880 nm) to stimulate cellular activity in the scalp, increasing blood flow and energizing hair follicles. This non‑invasive treatment promotes healthier, thicker hair growth by extending the active growth phase and reducing follicle inflammation.

What Is Blue Light Therapy for Hair?

A non‑invasive treatment using 405–470 nm blue light to reduce excess oil, combat dandruff‑causing microbes, and soothe scalp inflammation—creating a healthier environment for stronger hair.

Switching Between Red & Blue Modes

Just press the button to toggle between red and blue—aim for 10 minutes of each color per day.

How Often & How Long?

Use daily—10 minutes of red light followed by 10 minutes of blue light for a total of 20 minutes each session.

What's Inside

Red Light Therapy

Helps stimulate follicle activity and support thicker, fuller-looking hair.

Blue Light Therapy:

Helps balance excess oil and maintain a cleaner, healthier scalp environment.

Near-Infrared Therapy

Penetrates deeper to support scalp circulation and hair-follicle vitality.

Tony F. 5/5 Verified

So far so good. My scalp was getting itchy as I take finasteride and minoxidil and also prp treatment. It feels like I have nits. I’ve been wearing the cap for 10mins a day using the mix of blue and red light treatment and the itching goes within a few minutes, so something is happening! I’ve only been using the cap a few days but feel it’s been worth it so far…..
