Does What It Claims: Fine Hair Review
First, I'd like to thank Matrix for giving me this product for free so that I could review it. But please note that this review is my own. I have very fine, dry, bleached hair.

the mega sleek 96 hour anti frizz topcoat serum made my hair look noticeably smoother after just one use. it helped calm down frizz without making my hair feel greasy or heavy, which is always my biggest concern with serums. the texture is lightweight and easy to spread through the hair, and a little goes a long way. i also liked that it added shine and made my hair feel softer without looking oily. it worked especially well on humid days when my hair normally gets puffy fast. overall it made my hair look more polished while still feeling natural.

[I received this product in exchange for my honest review] Definitely keeps my hair not frizzy! After moving back to Texas the humidity always gets to my hair quick but once I started using this product it keeps my hair maintained and smells great as well! The product is light weight and isn't too oily!
