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!

Quality and effectiveness
Good value for money. I’ve used this product for over half a year. I spray it in my wet hair every time after I wash it, which gets the job done. My hair is still thin, but the spray increased the volume, so it doesn’t appear that I have less hair.

Good product. Easy to apply and doesn’t make hair greasy feeling. I think it does what it is advertised to do.

Does thicken but to sticky
Too sticky on my hair. Not the right product for me, but it does thicken.

Fresh minty scent with added body for thin hair
Love the scent, sort of a light mint and fresh! This is great at adding support and body to my straight fine hair. Never to heavy to sticky. Works on dry or wet hair too! Just use blow dryer to style! Love it

Perfect just perfect.. Read my review.
I fell absolutely in love with the detox shampoo, so I decided to buy this a try. It is fantastic. I can't say enough. First, the shampoo is magnificent. I have fine beach blonde colored hair and it leaves my hair feeling like silk. And then, when I spray this on, I feel I have double the hair, but not only that , it feels and looks like very healthy hair!!! Everybody's telling me what are you using? What are you using? And I've told them. I loved it so much that, as with the shampoo, I got my sister a bottle. She absolutely loves it also. Buy it. You won't regret it. Not sticky at all. Doesn't weigh your hair down. This product is perfection.

Ispessimento teorico
Almeno personalmente mi sono trovato molto male, impiastra i capelli e mi viene prurito tutte le volte che l'ho usato.

El pelo fino coge cuerpo y volumen
El bote llegó en perfecto estado y muy rápido. Lo he usado solo un par de veces aún, pero si he notado como mi pelo tiene más cuerpo y eso que lo tengo súper fino. Espero que con el uso se note más.
