- Glamour

"If you're constantly heat styling your hair, you need this"

- POPSUGAR

"Douse it on your ends for some much-needed shine or on your dry lengths for some hydration. Best part? It also boasts heat-protection benefits and is impossible to overdose"

- Byrdie

"Instead of frying my hair off, I’ve started using this heat serum. It protects your hair during heat styling and also leaves it smooth, hydrated, and silky (shout-out to the sea buckthorn berry in the formula).”

- Cosmopolitan

"Perhaps the best thing about it is its heavenly scent (if you've tried any amika products before, you'll know what I'm talking about)"

- Bustle

"Almost all the serums on this list can be used as thermal protectants, but this serum from amika specializes in that task. Reviewers rave about the soft, shiny, salon-worthy results they get with this, and how non-greasy and non-gloopy it feels, even on finer hair."
