Great hair thickener with heat protectant
I've used a ton of hair thickeners. I am seriously impressed with this one and appreciate that it has heat protectant, too. Yes, she's a bit pricey, but she works.

Gives hair the volume it deserves
[I received this product in exchange for my honest review] 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.

Renewed hair with ouai
[I received this product in exchange for my honest review] 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.

Thick spray
Thick Spray is a hair product designed 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 fine or thin hair. The scent is pleasant and the packaging 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 noticeably heavy, and not in the best way. Instead of a natural, lightweight fullness, the hair can feel weighed down. Overall, it’s still a decent product with good fragrance and practical packaging, but the slightly sticky and heavy feeling might not be ideal for everyone.

This spray doesn’t really do anything. I have relatively fine hair, I don’t see any change in texture, thickness or style when I use it.

The best!
Absolutely amazing product! My fine, curly hair has been lifeless lately (thanks perimenopause) especially when I blow it out, which I do often. I have never used a thickening product before so I wasn’t sure what to expect but I was pleasantly surprised when I finished my blow out and my hair was so full and bouncy. I curled it with my flat iron and the curls lasted until my next wash, which embarrassingly wasn’t for 5 days. I will never be without this again and highly recommend to all my midlife sisters or anyone with fine hair for that matter.

I really like it
[I received this product in exchange for my honest review] 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.
