OUAIThick Shampoo and Conditioner Set - Sulfate Free Shampoo and Conditioner for Thick Hair - Made with Keratin, Marshmallow Root, Shea Butter & Avocado Oil - Free of Parabens & Phthalates (10 Fl Oz)

I have blonde, color-treated hair, and I didn’t even know I had fine hair until I tried this. I assumed “fine” meant brittle and thin. Nope, just thinner strands and, in my case, low porosity that would quickly cause product build up.My hair never felt truly clean unless I went in with a detox shampoo, which obviously you’re not supposed to use all the time. But the fine set from Ouai has that same clean feeling without stripping/wrecking my hair.It looks fuller, feels denser, and I’m shedding way less - and I used to shed like crazy (with bright blonde hair and a closet full of black shirts, it was very obvious). I’ve barely had that issue since I switched! Ouai now has a customer for life.Including a pic in direct sunlight so you can see the texture, shape, volume, and shine this gives my hair!

My hair isn’t fine but isn’t thick either. But it does get super greasy so easily. This is literally the only shampoo & conditioner to have worked where I don’t get greasy the next day. Kind of expensive but literally hate having greasy hair. I love the smell & it also makes my scalp feel so clean!

I usually don't spend a lot on beauty products but I needed something to hydrate my hair and heard wonderful things about it. I could tell right away the difference in my hair on how soft it was after styling it. The scent is also wonderful if you like roses, my hair smelled great all day. I would highly recommend!

Because of my age and medical history, I have very thinning hair. I love these products because they make my hair have more volume, shine and look healthy. I highly recommend the shampoo and conditioner.

Very fragranced which is why the four stars. Other than that so far I don't have much in the way of oily hair hours after washing. It feels clean but not stripped. My hair feels soft and I haven't had any issues with staticky-ness. I went from Function of Beauty to this and I would take this over that at this point. I find just switching to a new shampoo seems to help for a while but then I'll need to switch again. That's not necessarily helpful unless you're like me.

This shampoo/conditioner duo has changed my hair! It smells great (a little strong at first but you get used to it). I used Oribe for years and always woke up with greasy hair the morning after showering. I also have tried Living Proof and Olaplex Their conditioners always left my hair tangled and dry. None of this happens with Ouai! It takes at least 2 days for my hair to become greasy.

It was only okay. It kind of seemed to dry out my hair, which is odd because I tend toward an oily scalp…but it didn’t dry it out in a good way. My hair was soft and manageable but seemed a little dull. I like other Ouai products but won’t get this one again.

Best shampoo and conditioner for fine hair. Leaves my hair so clean and then moisturized but not in a way that weighs down my hair. Must have.
