Fine Shampoo - Volumising Shampoo with Strengthening Keratin, Biotin & Chia Seed Oil for Fine Hair - Delivers Clean, Weightless Body - Paraben, Phthalate & Sulfate Free Hair Care - 300ml

Really great shampoo for fine, flat hair. It doesn't work miracles, you won't magically have full, thick hair... but it keeps my hair grease-free for 2 days (which is good for my hair type), smells great, and keeps my hair feeling soft and knot-free. The price is the best I've found online or in-store for this product and size. Same goes for the OUAI Fine Conditioner on Amazon.

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 HAVE FINE FAIR HAIR AND THIS SHAMPOO REALLY WORKS ON VOLUMISING. ACTUALLY A LITTLE TOO MUCH! I USED THE SHAMPOO AND CONDITIONER BUT IN FUTURE WILL ONLY USE ONE AT A TIME AS MY HAIR LOOKED A LITTLE LIKE A BAD HAIR DAY WITH FRIZZ.. WILL EXPERIMENT WHETHER ITS BEST TO USE JUST THE SHAMPOO OR JUST THE CONITIONER.IT

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.

It's magic on highlights. This duo shampoo and conditioner is out of this world - it has given my hair the curls I used to have, the volume is miraculous and the shine - but most of all it enhances the highlights in my hair. A bit pricey but generous in size. MAGIC

It arrived fast and it worked fine, however, I don't like the smell. It smells like a bar of soap.

Definitely going to buy again. It’s more than I pay for shampoo but I am really pleased with it. There is a shine on my hair I don’t get with my previous cheap shampoo. My hair looks better, cleaner. Also the cost of purchase is negligible because it will last ages. It’s a nice size bottle. I recommend. Months on and still happy with this shampoo. :)

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
