OUAI Medium Shampoo - Hydrating Shampoo with Coconut Oil, Babassu, Kumquat Extract and Keratin - Strengthens, Nourishes and Adds Shine - Paraben, Phthalate and Sulfate Free Hair Care Products (10 Oz)

This shampoo cleans well without stripping my hair and leaves it soft, smooth, and hydrated. It smells great and never feels heavy. The refill size is a bonus—more product and less waste. Easy 5 stars.

I bought a travel size QUAI shampoo just to try and have to report that it’s wonderful! It left my fine hair soft and shiny with amazing volume. It didn’t strip and dry my hair as many body-building shampoos do. Very light fragrance, no itchy scalp. A winner for me!

I bought the OUAI Medium Shampoo Refill because I needed something gentle enough for color-treated and keratin-treated hair, and it has worked really well for me. It cleans thoroughly without stripping, and leaves my hair feeling soft, smooth, and healthy. The formula has just the right balance—rich enough to nourish my hair, but not heavy or greasy. The scent is light, clean, and really pleasant, and it pairs perfectly with the matching conditioner. One of my favorite things about this refill is how cost-effective it is. You get a much larger amount for the price, and it’s more eco-friendly since it uses far less plastic than buying multiple bottles. If there’s a minor downside, it’s that using too much can feel a little rich, so a smaller amount works best—especially if you have finer hair. But overall, this shampoo has been a great option for maintaining both my color and keratin treatment. Overall: High-quality shampoo, gentle on treated hair, great scent, and a smart buy in the larger refill size. I’ll definitely keep repurchasing.

Ugh, didn't wanna love it, it's pricey, but it smells like designer stuff. Who doesn't want to smell rich?

This shampoo does give my fine hair a little more lift. However, the bottle is terrible. I have small, very arthritic hands. My hands were too small to grip around the bottle, and too weak to squeeze the shampoo out. I had to pour it all into a pump bottle that I had at home. A redesigned bottle would be wonderful.

I’ve been using OUAI Medium Shampoo, and it’s officially a staple in my shower. This shampoo is the perfect balance—it cleans deeply without stripping, and leaves my hair feeling soft, light, and fresh instead of dry or heavy. The scent is clean, luxe, and salon-level good without being overpowering. It makes washing my hair feel like a mini self-care moment rather than a chore. A little goes a long way so start small and work your way up as needed. Final verdict: If you want healthy-looking, bouncy, clean hair that still feels moisturized and touchable, this shampoo delivers. Worth every drop.

I bought this based on a news feed review of best shampoos for various types of hair. This is the best shampoo I’ve used in years. My hair has become finer over time and will lay dead flat if I don’t use some product or other. Now I just lightly blow dry and I’m done. Plus - it smells wonderful.

I've been trying to find a shampoo and conditioner that helps with volume, anti-frizz, and dryness. This shampoo and conditioner are GREAT for volume; however, I feel like my hair is more brittle. While it doesn't create frizziness, it feels dry, but overall looks shiny. Another thing that I've noticed is that the smell is SO strong. If you don't like the scent it has, I can guarantee it will drive you crazy-- Like it did for me. If you do like this scent, it's perfect for you since the smell stays in your hair for hours. I loved how easy the shampoo was to lather. With the previous brands I've used, I didn't have to rely on dry shampoo as much for non-wash days, however, I did notice that my hair appeared more oily on non-wash days while using this product.

Ho i capelli fini e da quando uso questo shampoo non riesco più a farne a meno! me li deterge senza seccarli o appesantirli. Lo adoro! Soffro di dermatite ma questo non mi dà noia.

This is such a good shampoo. Your hair with thank you. They feel clean right away and it does what is supposed to for fine hair, it gives you volume. It might be pricey but worth it.

Zeer tevreden het haar voelt echt anders aan en de hoofdhuid ook goed

Je ne peux pas mettre d’étoiles car j’ai fait une allergie, désolé

Really great shampoo for fine, flat hair. It doesn't work miracles, you won't magically have full, thick hair... but it keeps my hair grease-free for 2 days (which is good for my hair type), smells great, and keeps my hair feeling soft and knot-free. The price is the best I've found online or in-store for this product and size. Same goes for the OUAI Fine Conditioner on Amazon.
