I have dry, frizzy hair, and I have been trying lots of products which resulted in build up. This shampoo leaves my hair so clean, but it didn't dry my hair out. Instead, it left it soft, moisturized, and smooth. I've been using it for about a month now and my hair feels so beautiful and healthy. I was skeptical because it was so expensive, but I only wash my hair once a week so it will last me a while and the product is so good it is worth it. Also, it also smells amazing.

Honestly , I’ve changed shampoos so many times, trying to find what would help. My scalp had build up and was so itchy , I literally tried everything! I was just about to give up and I saw this at Ulta. Wow , has it seriously changed my life . I will be buying the conditioner next !

I LOVE THIS SHAMPOO. I am someone who washes their hair everyday (i know) and this is something so important to me on my new haircare journey of try's g to train my hair. Genuinely, I have never felt my hair without product buildup and Im shocked. Who knew honestly. The ACV is the real star of the show yet there is no unpleasant scent. YOU NEED THIS. Changed the game for me.

I have very thick curly hair that requires a quality conditioner and variety of products to contain. After using this shampoo my hair feels nice and soft and bouncy! I love my one day every other week that I wash with this shampoo. It also smells amazing! I will definitely buy again and try other products in this brand.

I’ve been having insane itchy scalp issues for a week. Usually washing my scalp helps but this was insane. So I had a detox shampoo from my fabfitfun box, used it, and holy moly. Y’all. My scalp is calm and not itchy and it’s not driving me insane ty OUAI!

This concentrated shampoo is designed to be used whenever you feel your hair needs a deeper cleanse! (Like after some real dry shampoo abuse!) I use it on average once a week to cleanse away product build up and other impurities. It’s nice to know I’m using something that will freshen up my hair after all the dry shampoo I use, but I haven’t noticed any visible changes from using this compared to my regular shampoo. It also has a very subtle scent that you can’t smell at all once your hair has been rinsed! (But I must point out that although this shampoo contains apple cider vinegar as a key ingredient, you cannot smell this at all!) I love how little of this product I have to use, even on my very long hair! A little bit goes such a long way that this 300ml bottle will last forever! I’m also absolutely IN LOVE with the scalp massager and cannot wash my hair without it now!

Wow!! I got this because I saw a tiktok creator say she uses it once a week to remove buildup. I don’t use lots of products but I do wear wigs and toppers and use my fair share of dry shampoo. I have used this twice and I am so in love with how my hair and scalp feel. I recommend using it once a week and making sure you condition properly after. This probably isn’t a good option for daily use, but you do you. Ps the smell is bomb!!!!!

I literally wash my hair once a week usually since switching to Ouai I could have NEVER! Said that a couple years ago! Some weeks I’ll wash it move in the summer as heat sweat and the need to but I use this weekly and it’s kept my hair so healthy before using it I can always tell if it’s super built up as I have go rinse and repeat :) but not always. I usually do two washes the first one is to get the yuck out and the second wash I leave in for about 2-3 mins and rinse the amount of clean and volume I get is amazing I love this shampoo and hope they NEVER stop making it I would lose it!

I got a sample of this shampoo and I’ve been loving it so much that I want to buy the full bottle. It feels luxurious wen it leathers and it’s actually quite a thick consistency. Makes my hair feel crazy clean! I only wash my hair 2 or 3 times a week so it definitely gets rid of all the dry shampoo buildup.
