OUAI Medium Shampoo Refill - Hydrating Shampoo with Coconut Oil, Babassu, Kumquat Extract and Keratin - Strengthens, Nourishes and Adds Shine - Paraben, Phthalate and Sulfate Free Hair Care (32 Fl 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.

Hair perfection. The softest most manageable hair plus your hair will stay cleaner, longer. The scent is not heavily perfumed but it does have a clean smell. If you have been wondering if you should try Ouai shampoo you absolutely should.

Purchased this during prime for $13 off the original purchase price. Definitely worth it! Scalp is clean, hair is soft. This product has a subtle scent. Used this on bleached hair. Works great in conjunction with the conditioner. I can really tell the difference between this and a drug store brand. I actually use less product on my hair and it works GREAT!

This smells so nice and makes your hair smell good throughout the day. It's more pricey than what I typically pay for shampoo and conditioner but the refill sizes are a good value. Gives your hair a nice clean feeling with softness. Doesn't dry out your scalp.

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.

Hands down my favorite conditioner. I have been using it for two years now and will not switch. I have medium curly hair and it keeps it extremely hydrated. The smell is fantastic. I saw less hair loss and you do not need a lot. I have medium to long hair and a quarter size works perfect.
