What the gurus are saying

This smoothing spray earns particular praise for transforming texture in wavy and thick hair, delivering noticeable softening and a glassy finish. The heat protection up to 450 degrees Fahrenheit makes it practical for blow-drying, though those with already-soft hair may find it simply enhances what's there rather than creating dramatic change. Not many gurus have weighed in yet, so there's limited take so far.

"Chris McMillan sent me the Glassy Smooth Blow Dry Spray, I was so excited about this because I'd heard incredible things. It was so funny for me to apply this on my hair and realize it just made my hair more of my hair, since I already have very soft hair. But [...] my partner has gorgeous wavy thick hair [...] that isn't the softest, and we started using this in her hair, and it is the most smoothing and softening hair product I've ever tried."

"Chris McMillan is one of the funnest human beings, so genuine, so sportic, so sweet. [...] He's the legend behind Jennifer Aniston's The Rachel haircut. He understands hair literally from every angle, and his formulas reflect his wisdom. [...] The Glassy Smooth Dry Spray is a sleek, boosting, frizz controlling prep spray that protects your hair up to 450 degrees Fahrenheit and delivers a glassy finish. I did use that today while I was styling my hair."
