Living in Japan, you quickly notice that some products wildly popular in Korea aren't necessarily the ones you see everywhere here.

In Korea, when you think of Japanese hair masks, fino is the undisputed champion, right?

Many travelers heading to Japan often grab a tub of Fino at drugstores or Don Quijote.

Even my friends stock up on Fino whenever they visit Japan, it's that popular!

However, as I've been exploring hair care products here, one particular item has consistently caught my eye since 2025.

That product is the Gyutto (ギュット) Corset Hair Mask.

With its green packaging, I initially overlooked it, but then I started seeing a significant number of reviews piling up on Japanese online beauty sites.

Currently, it boasts over 1,400 reviews on @cosme, showing just how many actual users are talking about it.

My curiosity got the best of me, so I decided to try it myself.

The Gyutto Hair Mask: A Rising Star in Japan

The product I've been using is the

ギュット コルセットヘアマスク

Gyutto Corset Hair Mask.

The name itself is quite unique, isn't it?

True to its 'corset hair mask' moniker, this product isn't just about making your hair soft.

Instead, its main focus is to tame frizz, flyaways, and unruly strands, giving your hair a more polished and controlled look.

What I Loved Most About It

Personally, I'm not a fan of that heavy, overly coated feeling that some hair masks leave.

Sometimes, you pick the wrong hair mask, and while it feels incredibly soft initially, after drying, your hair can feel weighed down, limp, or just sticky.

But with Gyutto, my experience was different. Instead of a heavy feel,

my hair felt light and gracefully tamed, with a lovely, flowing movement.

When I ran my fingers through my hair after drying, I thought, "Wow, this feels surprisingly light!"

Yet, it still managed to reduce the dry, brittle feeling at the ends, which I really appreciated.

What truly impressed me was how my hair moved – instead of feeling stiff, it had a beautiful, soft sway when I shook my head.

A Different Vibe from Fino

For those who've used the incredibly popular Fino from Japan, you're probably wondering what Gyutto feels like.

In my opinion, if Fino is for those who love a rich, deeply moisturizing hair mask, Gyutto offers a lighter, more refined finish.

Of course, the difference can vary greatly depending on your hair type and damage level, but I'm not particularly sensitive to these things, and even I noticed a clear distinction, so I believe others will too.

Indeed, looking at reviews from Japanese users, some mention their hair feeling "soft and well-managed," while others didn't feel a significant effect.

So, it's not a universal holy grail product for everyone, but I think it's definitely worth trying if you're bothered by frizz, flyaways, or hair that just won't stay put.

Who This Hair Mask Is For

✔ You struggle with easily frizzy hair

✔ Your hair feels dry, brittle, and hard to manage

✔ You dislike heavy, weighty hair masks

✔ You want soft hair but hate it feeling limp

✔ You're looking for new hair care products to try in Japan

✔ You're seeking a different experience than what Fino offers

My Honest Verdict After Trying It

In Korea, when Japanese hair masks come up, Fino is still often the first name mentioned.

But living in Japan and browsing drugstores and beauty sites, you realize there's a surprising variety of hair care products out there.

Among them, the Gyutto Corset Hair Mask is one I've recently tried and genuinely loved.

Instead of a heavy, sticky feeling, it gave me lightly managed hair with a delightful, flowing movement.

I was quite pleased with this finish.

If you're contemplating buying a new hair mask in Japan, definitely keep an eye out for the green Gyutto (ギュット).

However, hair products truly vary greatly in perceived effectiveness depending on hair type.

So, rather than calling it an "absolute life-changer for everyone!" I'd recommend it as a hair mask I personally tried and liked in Japan.

I've already finished one tub and am nearing the end of my second.

I also heard that Gyutto released a new hair milk on 09/15/2026.

I'm eager to try the hair milk too, and while I considered grabbing a Fino product, I think I'll go for the Gyutto version instead.

I haven't spotted where they're selling it yet, but I'll be sure to post a review once I try it out!
