Not for me
Everyone’s hair is different of course and this seemed to leave my hair sticky.

Not sure about this one
I used this, guessing about how much to spray on my hair, and found it left my hair sticky and dull. Did I use too much? It's hard to say without suggestions on the packaging.

The best thickening spray
This spray is amazing. It adds a subtle texture and a lot of long-lasting volume. The scent is incredible too. I have used it before drying and heat styling on my fine, thin, short hair. It is also nice for air-dry texture. A small amount goes a long way, but more can be used for more structure.

Smells really good, but had no thickening or volumizing effect on my shoulder length fine hair and made it greasy faster. Usually love Ouai but this wasn’t it

Gives your hair the volume it deserves
[This review was collected as part of a promotion.] I am a big Ouai fan! I love their scents and their hair and body care! Always receive so many compliments when I wear anything from this brand. I like using this spray when my hair falls flat when I’m styling. I spray on my roots and scrunch up a bit to make it look healthy and full. It’s what I was looking for on my already thick hair that sometimes gets weighted down by other products specially in the root area.

Surprising Volume
I have very fine hair and am in constant search for a product that actually gives me volume for more than 30 minutes. To my complete surprise, this stuff is it! I had a ton of volume after applying it to damp hair and then blow drying. Smell was pleasant too. Downside, when damp it felt like I didn’t use enough so I used more. Once dry, my hair felt like day 3 or 4 of not washing but it did have volume nonetheless. Would buy again!

Renewed hair with Ouai
[This review was collected as part of a promotion.] With my hair being somewhat thin in the summer times and the paces I have put it through, this spray makes my hair feel renewed. My hair does feel fuller when I put in the Ouai spray. Plus the spray smells really nice. I love the clean feel of my hair afterwards especially when I feel like I am having a bad hair day. My scalp feels renewed and there is no sticky residue from the spray either. If the spray is working this well, I can’t wait to try more products by Ouai.

Good product
[This review was collected as part of a promotion.] I really liked this product and I’m glad I got choose for it. It makes your hair super soft and no frizz! So excited to buy some more from the store. It also gives you some good volume.

Thick spray
[This review was collected as part of a promotion.] Is a hair product design to make the hair feel fuller and thicker. After using it, the hair definitely feels heavier and gives the impression of more volume, which can be helpful for people with thin hair. The scent is pleasant and the packing is convenient and easy to use, which makes the application quick and practical. However the texture it leaves on the hair is not my favorite, while it does make the hair feel thicker, it also leaves it a bit sticky and noticeable heavy, and not in the best way. Instead of natural, lightweight fullness, the hair can feel weighted down. Overall it’s a decent product with good fragrance and practical packing, but the slightly sticky and heavy feeling might not be ideal for everyone

Smells nice but not sure how much it actually works
This product smells amazing! I'm not sure if it actually does anything to make my hair look thicker. Maybe minimally, which is still more than nothing, but don't expect incredibly visible changes.

Not for Long Hair
This product smells great and provides a nice effect, but I have to use about 1/5 of the bottle to get a that result. The product has to be used throught the hair for a uniform effect, so there isnt really a way around this issue. It just isnt worth the money/use in my opinion.

Not the same product anymore
I *loved* Ouai's original Volume Spray. It worked like a dream and it smelled even better. I don't know what this imposter is, but it has neither of those attributes. Highly disappointed. Feels more like a bad texturizing spray from the early 2000's when we were babies and just learning how to do our hair. Try Kenra 13 if you want the old Ouai volume feel.

Thin/Fine hair's dream! 🤩
I've tried many other products for my fine thin hair and this product is superior to all others. It is absolutely a must have.

I liked it
[This review was collected as part of a promotion.] It does have some weight on it if you add a lot in the hair . It feels nice for a night out if you add it and style your hair I believe it gives volume kinda feels like a hairspray but lighter . It doesn’t make your scalp itchy or anything.

Love !
I started noticing my hair getting thinner . I bought the shampoo and thickening spray . It is a game changer . Have been using it for couple months and my hair seems healthy and definitely thicker. Definitely recommend.

Not worth it
[This review was collected as part of a promotion.] Unfortunately this didn’t work for me. I saw no big difference in how my hair looked and I didn’t like the scent so I stopped using it after a while. The scent to me smelled sour, but thankfully it wasn’t too strong. While I’ve liked other Ouai products, this was not one of them.
