I'd buy Matrix Mega Sleek everytime given the chance
I want to be clear that I received my Matrix Mega Sleek 96H Anti-Frizz Topcoat Serum for free in exchange for writing an honest review. This product is a heat-activated hair serum designed to fight frizz and result in long-lasting smoothness, especially in humid conditions. I found it to be effecti...

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. I also do professional keratin treatments to help keep my frizz at bay and to straighten it because my hair is not natural...

I don't think I got the full effect
Hair Type Very Curly Hair
This product is ok. Can't complain about it. I just used the blow dryer and not flat iron. But I'm putting a ponytail so I can tell then.
Works great! Imparts a good shine…
Hair Type Wavy Hair
I was impressed with this topcoat product. It does what it promises, although I can't attest to it lasting the claimed '96 hours' as noted on the bottle, I can't attest say that I've tried it both with and without heat and it works both ways! It definitely keeps frizz away too, smoothing the hair shaft down with the added shine benefit. It works better than spray shine hair products I've bought in the past and has more staying power. I would recommend this product! I received this incentivized product in exchange for my honest review.
Lightweight
I received this product in exchange for my honest review but I like this product! It's small so easy to travel with and definitely smooths out my frizziness. It's very lightweight and thin which is nice since it doesn't weigh down my hair
I wanted to give this five stars, but I just can't
Hair Type Wavy Hair
[I received this product in exchange for my honest review] I'm not even gonna lie cause I'd hate not to be honest in my review. This smells amazing but it's supposed to be self heating and it definitely is not. I don't like the way that it feels on my hair either. I like a lot of this brands other products. Just not this.
Would buy again
Hair Type Wavy Hair
[I received this product in exchange for my honest review] Shake well before you use it, I pumped it before shaking and it had a weird smell but after I shook it, it had a hint of vanilla smell and maybe cocoa butter. It's very lightweight which I really like a lot. A little goes a long way and it helped with my frizz and tamed my curls.
