Great Product
This is my favorite hair product. It makes my fine hair thicker, and it has increased body. I use this product every other day when I shampoo and there is never any product build-up. The smell of this liquid product is very pleasant and is a nice extra benefit. The product helps my hair hold the style for two days. it does not take much product to produce the desired effect, and it is well worth the price.

Run, don’t walk
It’s my very first time using OUAI anything, since I’m usually an Olaplex girlie and let me tell you, this product is worth all the hype. My hair is straight and on the thinner side. After washing I towel dried, split my hair into 3 sections and sprayed onto each section from root to ends (lightly). Then I gently massaged the scalp and rest of my hair to blend well. I immediately felt a bit more weight and after blow drying I looked like Ms. Universe, haha, I mean, it was way cooler looking than I expected. There was more texture and volume, whilst my hair still felt soft and bouncy. Highly recommend. It’s definitely a new staple in my daily hair care routine!
