"The Flex Hairspray by Living Proof is on Amazon Prime Day and I'm restocking it because I go through a lot of it. I think this is the softest hold hairspray that lets your hair still move without feeling crunchy, stiff, or sticky like so many hairsprays, and it doesn't seem to dry my hair out. I've been using this exclusively since I discovered it a few months ago."

"We have the Living Proof Flex Hairspray, which I have tried, and it was all right."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
