Their Promise: Will keep your hair hydrated and infused with texture and vitality during the cold season

My Test: I have to be honest, I'm already biased. I've been using ISO's Bouncy Creme and Bouncy Spray for months, and have deemed myself a loyal fan of the brand. ISO's Winter RX Duo didn't disappoint me at all. It kept my hair soft, not stringy. FYI, it was 45 degrees during the time of testing.

The Grade: A+
