FDA 510(k) Cleared

Built to Meet U.S. Safety Standards

CAYAMA is committed to delivering safe, reliable, and professionally developed hair growth technology. Our device has been reviewed through the FDA 510(k) process, providing an additional level of confidence for customers in the United States.

Clinically Proven Technology

Backed by peer‑reviewed clinical studies and real‑world patient outcomes

24-Week Randomized Controlled Trial Male Pattern Hair Loss

A 24-week trial in 91 men with androgenetic alopecia compared red light therapy to 5% minoxidil. Both treatments produced comparable improvements in hair density. Red light therapy showed fewer side effects, with only mild scalp irritation reported. This supports red light as an effective, drugfree alternative for male hair loss.

16-Week Double‑Blind Trial — Female Pattern Hair Loss

A 16‑week sham‑controlled trial in 47 women with androgenetic alopecia showed that the active treatment group achieved a 48.1% increase in hair count, compared to just 11.1% in the placebo group — a 37% greater improvement. No adverse events were reported. Red light therapy significantly improves hair count in women, with a strong safety profile.

12‑Month Prospective Study — Long‑Term Efficacy and Safety

A 12‑month study in 68 adults (51 men, 17 women) with androgenetic alopecia evaluated home‑use red light therapy. Over 48 weeks, hair density increased by 25% (from 99 to 124 hairs/cm²), and hair thickness improved by 15%. Investigator assessment showed 98% of participants achieved stabilization or improvement. Over 85% expressed satisfaction and willingness to continue. No safety concerns were reported.

Engineered for Regrowth

Medical‑grade LED technology designed to awaken dormant follicles and restore density.

At the core of CAYAMA lies a proprietary array of high‑intensity medical‑grade LEDs. Each diode emits a carefully calibrated wavelength of red light that penetrates the scalp to reach the hair follicle at the cellular level. This light energy is absorbed by the mitochondria, triggering a natural increase in ATP production — the fuel that powers follicle repair and regeneration.

The result? Dormant follicles are reactivated. Blood circulation around the hair bulb improves. Over time, this translates to visibly thicker, stronger, and healthier hair — without drugs, without side effects, and without leaving your home.

With consistent use, CAYAMA delivers measurable results you can see and feel. Because great hair doesn't happen by chance — it happens by design.

Works exactly as described

I've tried minoxidil and finasteride in the past, but I didn't like the side effects. CAYAMA is a game-changer. I've been using it for 6 months, and my crown area is filling in nicely. No drugs, no needles – just 30 minutes a day. If you're on the fence, just try it. You won't regret it.

Solid results after 3 months

Three months in and I can see noticeable improvement in my hairline. It's not dramatic, but it's definitely there. My barber even commented on it without me saying anything. The cap is comfortable and the app makes tracking sessions easy. Dropping one star only because I wish it came with a travel case.

 Life-changing for postpartum hair loss

After having my second baby, my hair was falling out in clumps. I was desperate. A friend recommended CAYAMA, and after 5 months, my hair is finally growing back. It's not just baby hairs – it's real density coming back. I wish I had found this sooner. Absolutely worth every penny.

Finally something that actually works

I've spent hundreds on serums, shampoos, and supplements over the years – nothing worked. CAYAMA delivered results in 4 months. My wife even said my hair looks thicker. The build quality is great and the customer service is responsive. I've recommended it to two of my friends already.

Good results, takes commitment

Let me be honest – this isn't magic. You have to use it consistently. I missed a couple of weeks due to travel, and I could see some shedding come back. But when I stick to the routine, it works. My thinning spot is definitely smaller. Just stay consistent and you'll see results.

Dermatologist recommended, I'm glad I listened

My dermatologist suggested I try CAYAMA before considering more invasive options. 5 months later, I'm so glad I listened. My hair density has improved significantly and my confidence is back. It's comfortable enough to wear while working from home. Clinical grade treatment at home – what more can you ask for?

Good, but give it time

I've been using this for about 10 weeks. Not a miracle worker overnight, but I'm starting to see baby hairs along my hairline. It's easy to use – I just wear it while watching TV. My only complaint is I wish the battery lasted a bit longer. Still, I'm hopeful and will keep going.

Patience pays off

It took a good 4-5 months before I really noticed a difference. So if you're expecting fast results, adjust your expectations. But once it started working, it was worth the wait. My hairline is filling back in slowly but surely. Solid product, solid science. Highly recommend to anyone dealing with male pattern baldness.

Finally seeing real results!

I've been using CAYAMA for about four months now, and I can honestly say my hair feels thicker and my part line is noticeably narrower. I was skeptical at first, but the consistent use paid off. No side effects, no scalp irritation – just patience and daily routine. Highly recommend for any woman dealing with thinning hair.
