Methodology
We started with @cosme’s (Japan’s largest beauty review platform) popularity ranking for shampoos, filtered to Japanese brands with an active Amazon US listing. Full methodology →
Out-of-stock items stay in the list below, clearly labeled, since restocks on these listings are common.
#1. YOLU Calm Night Repair Shampoo/Treatment (YOLU)
Amazon US status (as of July 15, 2026): ✅ In Stock — $35.00 (10.1 fl oz) (sold through YOLU’s own Amazon storefront)
@cosme rank: #9 in Shampoo & Conditioner (overall)
Pros
- From @cosme reviews: many reviewers say it leaves hair smooth and manageable with a gentle, widely-liked scent, and some with fine or thin hair say it adds a bit of body → best for people with fine or thin hair who want a crowd-pleasing scent.
- From Amazon US reviews: reviewers highlight strong lather and an elegant Neroli and Jasmine scent that isn’t overpowering, plus noticeably easier detangling and styling the next morning → good fit for anyone who wants an easier styling routine after washing.
Cons
- From @cosme reviews: a handful of reviewers with dry hair found the cleansing a little strong, leaving hair feeling dry or frizzy when they used too much, and the scent doesn’t always carry into the next day → worth easing up on the amount if your hair runs dry.
- From Amazon US reviews: more than one reviewer felt the bottle was small for the price → a real consideration if you go through shampoo quickly.
Koto’s take: This is the shampoo I’d point most people to first here — it’s sold through YOLU’s own storefront rather than a reseller, and the pattern across both markets lines up: good lather, a scent people don’t get tired of, easier hair the next day. If your hair runs dry, use less than you think you need.
Where to buy: Buy on Amazon
#2. plus eau Lipoa Shampoo/Treatment (plus eau)
Amazon US status (as of July 15, 2026): ✅ In Stock — $25.91 (11.85 fl oz / 2-pack) (sold through a third-party Amazon storefront rather than an official plus eau US store — double-check the seller line before you buy)
@cosme rank: #3 in Shampoo & Conditioner (overall)
Pros
- From @cosme reviews: reviewers describe a soft, lingering floral scent and a rich lather from a small amount, which several call good value per wash, plus a moisturizing finish that some preferred over plus eau’s own Mellow line for taming frizz → best for wavy or damage-prone hair wanting a gentle, long-lasting scent.
- From Amazon US reviews: still a small sample on this newer listing, but the ratings so far are five-star.
Cons
- From @cosme reviews: one reviewer with thick, coarse, wavy hair said it didn’t fully tame frizz despite trying it specifically for that, and the treatment can feel a bit rich for finer hair → a possible mismatch if your hair is already fine or thin.
- From Amazon US reviews: too new on this listing to have a real US track record yet.
Koto’s take: Lipoa (the pink line) reads as plus eau’s moisture-forward option, and Japanese reviewers who compared it directly to Mellow (the blue line) generally preferred it for taming frizz. The catch is the seller line — check it before you buy.
Where to buy: Buy on Amazon
#3. plus eau Mellow Shampoo/Treatment (plus eau)
Amazon US status (as of July 15, 2026): ✅ In Stock — $39.00 (15.2 fl oz / 2-pack) (sold through a third-party Amazon storefront rather than an official plus eau US store — double-check the seller line before you buy)
@cosme rank: #7 in Shampoo & Conditioner (overall)
Pros
- From @cosme reviews: reviewers like the strong, satisfying lather and a scent that’s noticeable without being overpowering, plus a smooth rinse-out that doesn’t leave hair feeling squeaky → best for normal-to-oily scalps wanting a thorough, refreshing cleanse.
- From Amazon US reviews: early ratings are five-star, echoing the strong-lather feedback from Japan.
Cons
- From @cosme reviews: a couple of reviewers with dry hair said it didn’t leave enough moisture or hold their style, and one noted the cleansing is stronger than the Lipoa (pink) version, leaving hair feeling squeaky without a treatment step → a possible mismatch for already-dry hair.
- From Amazon US reviews: too new on this listing to have a substantial US review base yet.
Koto’s take: Mellow (the blue line) is plus eau’s stronger-cleansing option, better suited to normal or oily hair than to dry, damage-prone strands. Like Lipoa, this listing runs through a third-party reseller rather than plus eau’s own US store, so it’s worth a quick seller check before you buy.
Where to buy: Buy on Amazon
FAQ
Is the Amazon US version the same formula sold in Japan?
All three listings are labeled “Made in Japan” and match the Japan-market product names. YOLU sells directly through its own Amazon storefront, while both plus eau listings ship through a third-party reseller rather than plus eau’s own US store — worth checking the seller line before you buy.
Why aren’t more of @cosme’s top-ranked shampoos on this list?
Most of the brands that dominate @cosme’s shampoo ranking — including THE ANSWER, ReFa, Predia, Cosme Decorté, Ayura, melt, and several others — don’t currently have an active Amazon US listing for the exact ranked product. This list only includes items we could confirm as actually purchasable.
Are these shipped from Japan, or from a US warehouse?
Based on the listings checked, all three ship domestically within the US rather than as direct international imports — worth confirming on the listing itself, since seller and fulfillment details can change.
Prices and stock status verified as of July 15, 2026, from Amazon.com with a US delivery address. Amazon inventory changes frequently — always confirm current price and availability before purchase.
