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.

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...

This product is pretty pretty good wasn't too sure about it at first, but I constantly use my hair every every day and hold what I said I would do and my hair can get frizzy as sometimes especially with the humid air and have really thick hair also so this very helped with silent with protected it really well. I definitely recommend this to anyone who styles their hair and uses heated tools.
Does the job!

I've been using this serum for a little while, and overall, it does a decent job at smoothing hair and cutting down on frizz. It leaves my hair feeling softer and has a nice lightweight finish that doesn't make it feel greasy or heavy, which I really appreciate. A little goes a long way, so the bottle lasts quite a while. The anti-frizz doesn't last the whole 96 hrs for me, but definitely does help for the rest of the day and maybe the next morning. The scent is pleasant but noticeable, so if you're sensitive to fragrance in hair products, that's something to keep in mind.

I have fine hair which is also damaged from years of coloring/heat damage and I am always looking for something to help with frizz especially in the summer time when the humidity is at its worst. I had high hopes for this product and while it did leave some shine, unfortunately it did nothing for the frizz. This could be a great product for others, but didn't work for me and I will not buy again.
Loving it!

I use the this after I wash my hair when it's damp. I then blow dry my hair as usual. I do see a difference when using this.
