heat defense hair serum, heat protectant serum
word on the street
"This amika serum is a standout for its buildable formula….it softens hair dramatically without leaving any product residue behind."
- 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."
- Elite Daily
