I tested the Nooance Hair Helmet X600: My review with results

The Nooance Expert X600 is a light therapy helmet for your hair, made by the same French brand that sells LED masks for the face. It packs 300 lasers and 300 LEDs, all at 655 nm, and it sells for $1,649.

My husband and I have both been using it since September, so here’s what we can already tell you, what Nooance’s proof really covers, and whether I’d spend that money on it.

What I tested: the Nooance Expert X600 hair helmet

I started in September 2026 and I do 3 sessions a week, 15 minutes each, in the evening. Nooance recommends one session every other day, which is exactly what my husband does with the same helmet.

Neither of us uses the Nooance hair serum for now. I want to see what the helmet does on its own first, and I’ll decide about the serum later.

Nooance hair helmet results after a few weeks

My own results

Honestly, few weeks is too early for me. Hair grows slowly, Nooance itself talks about 2 to 4 months before the first results, and I already have very thick hair, so I wasn’t expecting a big difference on my side. What I’m looking for is stronger, thicker strands, and I’ll tell you in December.

My husband is the more interesting case. His crown is getting a bit sparse and his temples have already receded. Those temples won’t grow back: hair helmet works on the hair you still have, it doesn’t bring back follicles that are gone (Nooance says the same in its FAQ).

What we’re hoping for is a denser crown, and temples that don’t recede any further. His hair is very fine to begin with, and it has been 4 weeks when I’m writing this, but when he runs his hand through it, he already finds it a bit denser. It’s a feeling for now, nothing more, but it’s a good sign this early.

Nooance also warns that some people shed more during the first two months: hairs that were already at the end of their cycle fall out sooner to make room for new ones. Good to know before you panic in week three…

These come from a GREDECO study on Nooance’s previous helmet, Le Professionnel, not the X600: 21 volunteers aged 25 to 55, over 6 months, with 25-minute sessions every other day.

I find them convincing, especially on the hairlines, and the X600 has more than twice as many light sources as the helmet they used so I’m hoping for even better results.

Nooance X600 helmet: 300 lasers and 300 LEDs

On this helmet, the lasers aren’t in the same chip as the LEDs. So the 600 sources really are 600 distinct points of light on your scalp, which is a very good point as it allows the helmet to properly cover all the surface.

Nooance also puts more lasers where hair thins first: the hairline, the temples and the crown. As you can see below, the jump from the previous helmet is huge.

The fit matters too, because the light has to sit as close as possible on the scalp. The helmet comes with two sizes of foam pads that clip on with magnets and adjust the inside width to your head. I personally pick the size that gives the snuggest fit, so the helmet presses down on my hair as much as possible.

And even with long, thick hair like mine, it’s not a problem: the light points sit right against the scalp.

How much light does the Nooance hair helmet deliver?

All 600 sources emit red light at a single wavelength, 655 nm. Nooance publishes 8.5 mW/cm² for the LEDs and lasers working together, so over a 15-minute session, that’s about 7.6 J/cm² on the hair.

To me, the interesting part is the comparison with Nooance’s own previous helmets. In their FDA file they were listed at 1.3 and 2.8 mW/cm², with 25-minute sessions.

So the X600 gives your scalp nearly twice the dose in 10 fewer minutes, which is why sessions dropped from 25 to 15 minutes.

Is the Nooance hair helmet FDA cleared?

Yes but not the exact X600. The FDA file K231321 covers Nooance’s two previous helmets, cleared to promote hair growth in men and women with pattern hair loss. The X600 is a different model, so that clearance doesn’t carry over to it.

Nooance doesn’t claim it either: its manual says the helmet isn’t intended to diagnose or treat any disease. In my opinion, that’s because hair loss is a medical topic, so Nooance prefers to sell the X600 as a beauty device for the moment.

The claims on the product page (slows hair loss, redensifies, strengthens) all point to a GREDECO study on the X600 itself, with 21 volunteers over 6 months but that study is still running. I assume that this study will be published in next few months, and I will look closely after it to assess its results.

Wearing the Nooance hair helmet during my routine

I find it very convenient as it’s not restrictive at all, even less than an LED mask. Your eyes stay open, so we just put it on in the evening and watch TV. At 1.4 lbs, it sits on your head and you barely feel it. And it’s so much simpler than going to a clinic for light sessions!

Toward the end of the session, it gets slightly warm on the scalp, but it never bothered me. Nooance says that warmth comes from the lasers.

The remote control is simple and easy to use, it contains the battery and is connected to the helmet by a cable. Nooance advertises 8 to 10 sessions per charge. I couldn’t say exactly how long it lasts, but I think it’s at least that long. I’ve never had any charging problems, the timer flashes when the battery is low, so I put it on charge after a session where I see it flashing.

On the safety side, the helmet only starts once it’s on your head and pauses if you take it off so you can not look at the lasers. The light points inward, toward the scalp, and the lasers are Class 1.

Nooance hair helmet price: is $1,649 worth it?

The X600 costs $1,649 on Nooance’s shop, with a 2-year warranty. My code TESTEMILIE15 takes 15% off and works on the helmets too, which brings it to about $1,400 (how to use the Nooance code).

It’s a lot of money, I know. But in my opinion it’s a good long-term investment for your hair, whether you have a hair problem or not, since it also makes hair look better. Plus, in our home, two people use the same helmet.

Nooance X400 vs X600: which hair helmet should you pick?

The X400 has 100 lasers and 300 LEDs, at the same 655 nm and with the same 15-minute sessions, for $1,199. I tried it, and it’s exactly like the X600 in look and comfort.

The only difference is the lasers: three times fewer. That’s why I find it less interesting, and why I only use the X600, to get the most out of every session. Nooance sees it the same way: the X400 for the first signs and the beauty of your hair, the X600 when density loss is already visible.

Who shouldn’t buy the Nooance X600 hair helmet

Am I still using the Nooance hair helmet?

I recommend the Nooance Expert X600 if you’re ready to stick with it for months. The light it delivers is well above Nooance’s previous helmets, and it fits into an evening without any effort. And if you already own the Nooance Elite X600 LED mask (you can read my review here), the two work on different areas, and you can use both on the same day.

About Emilie

I have tested LED masks since 2023. I buy the devices, use them for weeks, and read the spec sheets nobody reads, because this market runs on numbers most brands never publish. Not a dermatologist, and I say so whenever a question needs one.
