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...

Hit or Miss Mega Sleek

The Mega Sleek 96 Hour Anti-Frizz Topcoat Serum was a hit or miss with my hair, unfortunately. I have long, curly, frizzy, unruly, coarse hair and although I did use the mega sleek as directed, I got shine, but it really didn't present any anti-frizz at all. Since we were given a full size product, I am excited to keep trying this and seeing how it works.

Great product! Replaced my other hair serum.

First, I received this item for free in exchange for an honest review. So, I recently tried the Matrix Mega Sleek 96 Hour Anti-Frizz Topcoat Serum, and I was honestly impressed with the results. The serum has a really rich, sweet scent—kind of like pistachio, caramel, and vanilla—but it's not overpowering. I applied it to damp hair, mostly through the mid-lengths and ends, and then blow-dried as usual. Right away, my hair felt smoother and softer, but what stood out most was how lightweight it was. Even though it's a serum, it didn't make my hair greasy or heavy, which is a big deal for me since I have fine hair. After styling, my hair looked sleek and shiny, and it stayed that way for days—even through a really humid day when I usually get tons of frizz. I didn't have to touch up with heat tools as often, and it still felt fresh after a couple of shampoos. I will say, a little goes a long way. The first time I used too much, my hair looked a bit flat until it absorbed fully. Once I figured out the right amount, though, it was perfect. Overall, it gave me a smooth, salon-like finish without the weight, and the frizz control is no joke. I'll definitely be keeping this in my rotation.
- very nice for anybody !

You just shake up the bottle - put a pump or two into the palm of your hand and rub it through your hair. It smells great and it is not like other serums that are almost sticky feeling. I love it!
