This month’s top picks across all categories →
#1. plus eau Lipoa Shampoo/Treatment (plus eau)
Buying note: 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: #7 in Shampoo & Conditioner (overall)
Pros
- Rich Lasting Scent — Reviewers describe a soft floral scent that lingers and a full lather from a small amount, plus a moisturizing finish that some prefer over plus eau’s Mellow line for frizz, which suits wavy or damage-prone hair that wants a gentle, long-lasting scent.
- Early Ratings High — The sample on this newer listing is still small, but the ratings so far are five-star.
Cons
- Rich For Fine Hair — One reviewer with thick, coarse, wavy hair felt it did not fully tame frizz, and the treatment can sit heavy on finer hair, so it may miss if your hair is already fine or thin.
- Thin US Track Record — This listing is too new to have a real US history 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: Check price on Amazon
#2. plus eau Mellow Shampoo/Treatment (plus eau)
Buying note: 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: #8 in Shampoo & Conditioner (overall)
Pros
- Thorough Cleanse — Reviewers like the full, satisfying lather and a scent that comes through without taking over, plus a clean rinse that does not leave hair squeaky, which suits normal-to-oily scalps after a refreshing wash.
- Five-Star Start — Early US ratings are five-star and echo the strong-lather feedback from Japan.
Cons
- Light On Moisture — A couple of reviewers with dry hair felt it left too little moisture and did not hold a style, and one found the cleansing stronger than the pink Lipoa version, so already-dry hair may want the treatment step or a different pick.
- Thin US Reviews — This listing is too new 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: Check price on Amazon
#3. YOLU Calm Night Repair Shampoo/Treatment (YOLU)
Buying note: Shampoo 10.1 fl oz + conditioner 10.5 oz set. Sold through YOLU’s own Amazon storefront.
@cosme rank: #18 in Shampoo & Conditioner (overall)
Pros
- Smooth And Scented — Reviewers get smooth, manageable hair from a gentle, widely liked scent, and some with fine or thin hair notice a little added body, which suits fine or thin hair and anyone who wants a crowd-pleasing scent.
- Easier Styling — Reviewers point to strong lather and a soft Neroli and Jasmine scent, plus easier detangling and styling the next morning, so it fits anyone who wants less work after washing.
Cons
- Strong Cleanse — A few reviewers with dry hair found the cleansing firm, with hair drying out or frizzing when they used too much, and the scent does not always last to the next day, so ease up on the amount if your hair runs dry.
- Small Bottle — More than one reviewer felt the bottle runs small for the price, which matters if you go through shampoo fast.
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.

How to choose Japanese shampoos
Japanese shampoos usually come as a set with a matching treatment, which is the Japanese word for conditioner. Pick the pair by hair texture and scalp, then let scent decide between close calls.
- Fine or thin hair: YOLU Calm Night Repair is the pick for body without weighing hair down.
- Wavy or damage-prone hair: plus eau Lipoa is the gentler, smoothing option.
- Normal to oily scalps: plus eau Mellow gives the most thorough, refreshing cleanse of the three.
Use the set together. Japanese lines tune the shampoo and treatment as a pair. Mixing brands works, but the finish reviewers describe usually assumes both bottles.
Take scent seriously. Fragrance is a big part of how Japanese shoppers rate hair care, and these scents linger. If you are sensitive to fragrance, smell-test the line before buying a full set.
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.
What is the most popular shampoo in Japan?
Of the picks you can buy on Amazon US, plus eau Lipoa ranks highest on @cosme’s shampoo and conditioner ranking, at #7 as of September 29, 2026. plus eau Mellow follows at #8.
What is a hair treatment in Japan?
Treatment is the Japanese word for the rinse-out conditioner that comes paired with a shampoo. Most Japanese lines sell the two as a set, and some add a leave-in oil or mask as a third step.
