I have waist-length wavy hair that's course and thick. And often, it's pretty untameable. Even when I straighten it or blow it out, it can get kind of...fluffy. Enter Amika. I got a tiny tube of this mask in my birchbox and am a COMPLETE convert. It makes my hair softer and more manageable than anything I've ever used before. It smells amazing, a tiny bit goes a long way, and I don't even have to blow-dry anymore! Since first trying the mask, I've purchased shampoo, blow-out spray, dry shampoo -- the works. I am a complete and total Amika convert, and I highly recommend it to any and everyone!
