    As soon as it arrived, I already tested it for 1 hour. Honestly, the cap is very comfortable to wear, it's not too hot, and it doesn't press on your head. We'll see, of course, in the long term whether it's effective. In the meantime, I highly recommend it as well as the seller. 👍

    After the 17th day, I can confidently say that I am positively surprised. The product actually works. I notice a lot less hair on my scalp where there used to be very little hair. I use it once a day for 20 minutes on one program and 20 minutes on the second program. I will continue using it in the future as I have seen results so far. I have high hopes. I highly recommend it.

    Quality is good. I am using the cap for one month now. I can‘t say anything about the effectivity, because it is still too early to assess. The cap is a little bit too big and might slip off of your head if you are not careful.

Red light therapy isn't just a trend — it's part of the daily routine for some of the most health-obsessed people on the planet. Tech entrepreneur Bryan Johnson, known for his extreme anti-aging protocols, wears a red light therapy cap every morning as part of his hair loss reversal routine. He's far from alone — longevity and biohacking communities have widely adopted red light caps as a core tool for hair health. NMNXtrallux
