  • Lightweight but Nourishing
Size: 10 Fl Oz (Pack of 1) Style: Fine Hair Shampoo - Full Size
This shampoo leaves my hair clean without drying it out or making it flat. Smells amazing and actually makes my hair feel fuller. Expensive, but the quality is there.

  • Ouai is awesome!
Size: 10 Fl Oz (Pack of 1) Style: Fine Hair Shampoo - Full Size
Lathers and cleans well and smells amazing! Does well with my wavy curls. I have fine hair but lots of it. Ever since starting with Melrose Place travel size perfume I’ve been getting more Ouai. Love the detox shampoo! Highly recommend but I only use around twice a month. Great to get rid of product buildup and if you have hard water like we do. Then the fine hair shampoo and conditioner, curl cream, body wash and shower gel. Love all Ouai! It all smells amazing! My daughter loves the St Barts smell but I love Melrose Place. ... show more

  • Definitely worth trying
Size: 10 Fl Oz (Pack of 1) Style: Fine Hair Shampoo - Full Size
Let's start with the smell. Some say it's overpowering and it is very strong, but I actually like it. I only just started using this so I can't say for certain if it has made a difference in my hair as it takes time. With that being said it cleans hair well and does make my fine, wavy, low porosity non chemically treated hair feel and look great. A little goes a long way so price may be high for some but it will last a long time. As of now I would def recommend giving it a go. ... show more

  • Amazing Shampoo Option for Fine Hair!
Size: 32 Fl Oz (Pack of 1) Style: Fine Hair Shampoo - Refillable Size
I love how healthy and strong my hair feels while using OUAI! It leaves my hair soft, light, and refreshed without weighing it down. The scent is absolutely amazing—luxurious but not overpowering. Plus, I really appreciate that they offer refill options, which is both convenient and eco-friendly. The only downside is the price—it’s definitely on the expensive side. However, given the quality and results, I think it’s worth it! If you're looking for a high-end shampoo that truly delivers, this one is a great choice. ... show more

  • Great product - just not a fan of rose-y 🌹 smell.
Size: 10 Fl Oz (Pack of 1) Style: Fine Hair Shampoo - Full Size
So far so good! Great product so far within a week of using it. I’m very oily hair and this keeps its pretty light weight and soft after. I use it with a scalp massager for a deeper cleanse. Only reason I give it 4 stars is the rose smell (reminds me of old lady perfume). However, it smells nice once it’s dry and is very faint. ... show more

  • Read the negative REVIEWS!
Size: 10 Fl Oz (Pack of 1) Style: Fine Hair Shampoo - Full Size
Recently tried their detox shampoo which I loved, so I wanted to give this a try for regular shampoo. Before purchasing I read the more recent reviews which were all positive. Well I should've kept reading! The first time I used this I just used for spot shampooing my face frame pieces. My husband immediately commented on the scent and how strong it was. He said it hit the back of his throat and he could taste it, that's how strong the scent is. Keep in mind, I didn't use alot the first time bc I didn't shampoo my entire head,just the front. Anyways, I went to brush my hair after and it was so tangled and gnarly. I thought weird maybe it's just from the summer, the pool, working out etc. A couple days later I washed my entire head with it. Again my hair was so tangled and dry feeling even when it was wet. When I was finally able to comb my hair I looked down at my vanity and had a good amount of breakage. Next I blow dried my hair. It was a frizzy mess and the ends were extremely dry and coarse feeling to the point where I sprayed leave in conditioner on them. After this fiasco, I thought to myself I can't be the only one, so I went back to the reviews and selected the 1 star reviews. These are spot on! Everything everyone said I experienced with this:the dryness, breakage, inability to comb. People also started talking about hair loss. Which honestly got me so nervous I washed my hair again with a more hydrating shampoo this time and deep conditioned. Now my hair feels alot better. I can't stress enough to steer clear of this stuff. This stuff doesn't even deserve 1 star and should be taken off the market. ... show more

  • Luxury shampoo you deserve
Size: 32 Fl Oz (Pack of 1) Style: Medium Hair Shampoo - Refillable Size
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.
