[I received this product in exchange for my honest review] I have used Redken products in the past and had a favorable experience, so I was very excited to try this.

It's a no from me
I have thin hair and this made my hair feel dry, frizzy, and like straw. It's especially hard to blow dry with this in my hair, as it is "grippy" and the brush will not glide through while styling. I just really don't like the way this feels in my hair at all and will be returning.
Did not work for me
This left my hair feeling greasy and heavy. I will not purchase again!
Thickens and lightly holds
I bought this for my husband who has extremely fine and thinning hair on top.

Leaves a weird residue
Hair Type Straight Hair
[I received this product in exchange for my honest review] This made my hair, very sticky and unmanageable. I didn't notice any problems but as soon as I started blow drying, I could tell there was a film on my hair it smells. There's no problem with that.
Fine Mist
[I received this product in exchange for my honest review] I was skeptical about how this spray would feel on the scalp but it was actually so fine that I could not even tell I had applied it. There is a subtle scent but nothing overpowering, it is almost spa like. Packaging is sturdy and of high quality.
