If you've noticed girls (and boys!) wearing weird LED hats or futuristic combs popping up on TikTok and Instagram, don't be surprised: Red Light Therapy is being touted as the savior of thinning hair. But does it really work, or is it just another trend that will fade away once the next season rolls around?
According to real dermatologists, not just influencers, red light therapy isn't magic — but it's no joke either. Serious studies from sources like Vanderbilt University, the NIH, and specialty clinics in the US show that using red light waves can:
- Improve blood circulation in the scalp;
- Extends the hair growth phase;
- Reduces inflammation and helps "awaken" follicles that have been "sleeping" in the winter.
Translation: you'll see thicker, stronger, more vibrant hair. According to a 2017 study, after 17 weeks of use, patients saw 50% more hair growth. Yes, 50%.
But what happens in practice?
The most popular devices are LED hats, light combs, or even infrared devices that you put on your head. You have to use them 3–5 times a week for 10–15 minutes, for several months in a row. It's a process.
Who is doing this?
In addition to the girls from TikTok, red light therapy is also being embraced by names like Kourtney Kardashian (who always has a futuristic device in her hand), Chrissy Teigen, and even some men like Joe Jonas and David Beckham (shhh, they don't admit it publicly, but fans have found out).
Is there any slop?
Overall, it is a very safe treatment, but it does require patience and investment. Good devices range from €200 to €1,000 – but they are certified and have LEDs that don't burn your scalp. Also, it won't replace other medical treatments if you have severe hair loss problems.
So if you're ready to get serious about your hair care routine, this is a modern, painless way to go. Bonus? You can look like a character from "Stranger Things" while giving your hair a chance to grow back.
