Shampoo is sooooo good for thin fine hair 5 stars!
Whoooo! This shampoo is truly amazing for thin fine hair. My hair looks and feels so good. It looks full light not weighted down. Pricey but worth it. I just love it. No smell a little goes far. Will be ordering some more soon. You wouldn’t be disappointed with this shampoo product just a little extra cost goes far.

Wonderful shampoo for fine hair
This product is amazing! I'm older and have always had fine hair. This shampoo somehow makes it thicker. I only wash my hair once or twice a week and don't use conditioner. Has a nice smell but not loaded with perfumes like cheaper brands tend to be. My hair feels clean and looks healthier and thicker after washing. I've used it for 6 months and still have half a bottle —it lathers up well so you don't need to use a handful to get long hair clean.

doesn't leave a residue, works for my fine hair
this is a clear rather than creamy which might indicate it's not weighed down by a bunch of emollients. It doesn't take much to fully lather clean my shoulder-length fine hair. (I do have a soft water conditioner - Phoenix has very hard water). Lovely scent, my hair is soft after drying and styling. Like any salon type brand it's bit pricey but since I need a relatively small amount each wash ut works out for me.

Great shampoo for thin hair
I absolutely love this shampoo it smells so good I get lots of compliments from people asking what kind of shampoo do you use? lol I don’t use conditioner because it weighs down my hair. I only use a light spray in and I only washed my hair maybe twice a week so I don’t strip my hair but this actually is a great shampoo. I just wish the price was a little less and the smell is very light. You don’t need to use a lot for it to lather up.

LOVE LOVE LOVE
I don't typically write reviews however I'm in love with this shampoo! I have fine colored treated hair so it's hard to find a shampoo that doesn't weigh my hair down. Truest me when I say I've tried most all of them? I read the reviews and decided to try Ouai. I'm so impressed with the product. Not only does it smell amazing and lathers well it makes my hair soft and fuller. My boyfriend is your typical alpha male and I had the travel size in the shower on our last cruise. He literally came out and said that shampoo smells so good and lathers nice. I about fell out. He hardly notices anything!

Worth the price
I wanted to use this shampoo over several weeks before writing a review. My first impression was that it smelled like dish detergent and not a shampoo. It has stood up to much scrutiny and I rotate it for every other shampoo. It’s not harsh, protects color and leaves my hair manageable.

Great shampoo - lots of lift!
This shampoo is great. My hair is long and not very thin, but it definitely benefits from the lift this product provides. Leaves my hair with a nice shine, feeling clean and soft. And curls seem to last longer. The shampoo is also very thick - a little goes a long way!

Wonderful shampoo for fine hair
I have very fine straight hair and it has never responded well to things designed to add body to it. Then I discovered this shampoo and it has worked very well for me. It adds body and fullness without heaviness and it doesn’t leave my hair greasy or static he dry. It’s expensive, but you use very little of it at a time so a bottle should last a good long while. Incidentally, I read about it in the New York Times wire cutter column. Great recommendation!

Despite what others say....
I have been using Champo for a year and it made little or no difference to thickening my hair. Thought I would try a change and this came up. Look it's ridiculously expensive and I dont for a moment think it will restore hair once the follicle damage has occurred but I LOVE IT! I think it smells expensive and the packaging is chic. You really dont need very much as it lathers like mad - probably means it's full of sulphates - but to me it means that it will last a long time. I have short hair so not overly concerned with drying effect - this may be what makes hair feel fuller. My hair feels weightless and definitely has more body. I'm enjoying it!!
