OUAI Fine Shampoo Refill - Volumizing Shampoo with Strengthening Keratin, Biotin & Chia Seed Oil for Fine Hair - Delivers Weightless Body - Paraben, Phthalate & Sulfate Free Hair Care - 946ml

This is a fantastic shampoo for me with fine hair. It has made such a difference to my hair giving it more volume. I love that it’s paraben and sulphate free. It also lasts a long time as I don’t need to use much and smells divine! I highly recommend it.

I used to wash my hair every day or every other day because of grease, but thanks to this shampoo, I can now go up to 4 days without washing. It smells absolutely beautiful, and the packaging is just as lovely—makes it a pleasure to use every time!

Nice formulation which I find thickens my hair quite noticeably. Good quality packaging and a handy size for gym bags. A bit pricey though, so one star off for that.

Wow. Wow. Wow!I have a lot of very thick, coarse hair and more often than not, my previous shampoos tend to mat the hair in the wash process and then detangle in the conditioner stage.This product - OUAI washes hair making it immediately soft. Paired with the conditioner and BOOM! You have amazing looking, feeling and smelling hair. The fragrance is divine.Another thing to note is that since using this product, my hair seems to not need to be washed as often and I can push back wash days by at least another day - which is helpful as this is a very expensive but amazing product.

One of the best shampoos I've used. I've got thick, dry hair and I struggle with it being too dry and frizzy. This leaves my hair soft, shiny and manageable. It also smells gorgeous

I usually read some reviews before buying products and then weigh up the average. For this shampoo, although expensive, I have found it really good. I am fortunate that i do have thick and the shampoo has been brilliant, not only on my hair but also my scalpe, which can tend to be very dry. It cleans my hair really well, but doesn't leave it feeling heavy or limp and the shampoo smells so good, even when my hair is drying.

It lather quite well with small amount. Hair feels clean and quite smooth, don't have any tangle problem. However the smell is too strong for me and my scalp feels a bit itchy. I would prefer something more natural, will not buy again

I don’t tend to use conditioner so this shampoo is perfect as it gives you volume but a lovely shine and smoothness to your hair. Thumbs up from me!
