Too scented, but works great.

5 months ago
I love this product and how thick it makes my fine hair, but the scent is so overpowering it's too much. I get migraines, and using this product gives me an instant migraine. I sure do wish it didn't have fragrance, or essential oils were used to give it a scent.

Yes, I recommend this product.

Works. But not a fan.

8 months ago
This like the other products included with this review does appear to thicken hair. However I don’t think I like the texture it creates as I don’t really style my hair and I feel like I need a shower sooner to wash it out.

Really good at making hair fuller but wish it was

8 months ago
Let’s start with the good: using this product (along with the other items in its Garnier Fructis collection), I did notice fuller, healthier looking hair. The texture and feel of the spray in my hair was also pretty nice once I got used to it. My only complaint was that the extra weight added by the spray made styling a little bit more difficult. It wasn’t thick enough to help hold up a style but wasn’t thin enough to avoid adding resistance during styling. I wish it had been a little bit heavier so it could double as a styling gel. Otherwise, recommended!

Nice Hair Spray

9 months ago
To be honest, this is not a product that I really use. However, I can say that for the few times I've used it, it appears to be a pretty good spray that left my hair feeling soft but not sticky or stiff. It's is easy to use, and the scent is not off putting like a lot of other hair sprays. It is also affordably priced

Love this line!

11 months ago
I absolutely love this line they absolutely have changed my hair. My hair not only has more volume but also is so much healthier and soft. It is also very easy to use and does not take long to go though the whole routine. I love thickening spray and how it really finishes off the whole process. Couldn’t recommend more especially for the price!

Q: Do you think you'll ever make this line fragrance-free? These scents do not vibe with the migraine girlies.

    Q: Can this thickening spray be used with the repair serum and do you apply it after the leave in serum? My hair is definitely weak and in need of repair but this line is intriguing me because the damaged hair has always been fine thin and straight. Whaiff
