K KerotinVolumizing Mousse-Lifter Foam for Instant Hair Definition-Lift style, Conditioning Mousse for Shine - Boosts Hair Thickness, Ideal for Fine and Thinning Hair - Cruelty Free, Made in the US

This is the best volumizing mousse I've ever bought. I was skeptical because I've purchased so many in the past. I have really fine hair, and not much of it, and this works really well. I only use one pump in my hand and I get lots of volume without residue of any kind.

Works great but doesn’t last a second day.

My hair is very fine, so this product gives me full hair that is still soft and smooth.

I follow an influencer glamgabby on YouTube who raved about this mousse, She also said that it works even better with the root booster. I purchased both and was so hopeful that the product would do what she said it would do. Neither work.I have tried the combo 5 times now and used different amounts of products to see if I could find the perfect mix. A few days ago I used the maximum amount of mousse and more root boost spray thinking more product would work. It left my hair feeling really funky and did not hold a curl over an hour.So disappointed!

I have extremely sensitive skin, including my scalp. I wanted more volume for my short baby fine hair, but needed something with little to no fragrance. This mousse was a great find. Lightweight, adds nice volume, and has almost no smell. It’s not sticky and doesn’t irritate my scalp or make it itch. One pump is plenty of mousse for my short hair, so it’s economical too. Will definitely buy again.
