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."

    A MUST HAVE!

    i was using Morrocan oil protect defense spray when i used it, it made my hair feel knotted and felt like i was playing tug of war with my hair when blow drying it, it also left a heaviness and horrible residue in my hair, so i was like i need to find something else to use!! Then, i googled "best heat protectant for hair" and Amika Blockade was like #1 on the list of products to use, so i read the reviews and they were all great, so i purchased a bottle, and just started using it yesterday. it is AMAZING!!! definitely lives up to its 5 star ratings, and leaves my hair super silky, none tangly, no knots, shiny, and smelling good! YES, please buy this product, its a game changer!!
