Red light therapy for hair loss, answered.
What is red light therapy?
Red light therapy shines a specific kind of red light on your skin. Your cells absorb it and use it as energy. On the scalp, it's used to support hair follicles that are still alive. It doesn't hurt, it doesn't get hot, and there are no drugs involved.
Does red light therapy really work for hair loss?
Several clinical trials over the last 10+ years found that people using red light grew more hair than people using a fake device. Those trials tested other devices, not Theracap, and results differ from person to person. It works best on thinning hair — not on areas that have been bald for years.
Why does it matter when I start?
Hair loss gets worse over time. Follicles shrink, make thinner hairs, and eventually stop. Once a follicle is gone, red light can't bring it back — nothing can, except a transplant. The sooner you start, the more hair you have to save.
How long until I see results?
Most people notice less shedding after 2–3 months and fuller-looking hair after 4–6 months. Hair grows slowly, so you need patience. That's why you get 180 days to try it.
How do I use it?
Put it on, press the button, and wear it for 10 minutes. It turns off by itself. Do it once a day.
Is it safe?
Yes. Red LED light doesn't burn or damage skin. A few people notice a warm scalp or a little extra shedding in the first weeks. Don't use it if you're sensitive to light or take medication that makes you sensitive to light. If you're pregnant or have a scalp condition, ask your doctor first.
Does it work for women?
Yes. The research covers both men and women with thinning hair.
Can I use it with minoxidil or finasteride?
Yes. Many people combine them. If you use a foam or liquid, wear the cap first, or wait until your scalp is dry.
Do I have to keep using it?
Yes. Hair loss doesn't stop, so you keep going to keep your results. Many people drop to a few times a week once they're happy.
What light does Theracap use?
660 nm red light and 850 nm near-infrared light, spread across the whole inside of the cap.
How does it compare to laser helmets, minoxidil or finasteride?
Laser helmets use the same kind of light but typically cost $550–$3,000 and keep you sitting still. Minoxidil and finasteride are drugs you take or apply every day, for $20–$90 a month. Theracap is a one-time $449, drug-free, and can be used alongside any of them.
What if it doesn't work for me?
Send it back within 180 days for a full refund. No fees. It also comes with a 2-year warranty.
Is Theracap FDA cleared?
No. Theracap is a wellness product, not a medical device. It hasn't been evaluated by the FDA and isn't meant to diagnose, treat or cure any disease. If your hair loss is sudden or patchy, see a doctor first.
