At home treatment as good as a Keratin Treatment
Matrix Mega Sleek is fantastic. The shine, control, and protection of my hair are just like when I spent hundreds of dollars on Keratin Treatment. I love it!

Great smoothing product with just a dab
[This review was collected as part of a promotion.] Thank you Buzz Agent and Matrix for this free sample of Mega Sleek 96 Hour Anti-frizz Topcoat Serum in exchange for my honest review. This product works extremely well in my hair with just a small amount. Everything was super sleek and smooth. It smells great and normally I would be worried about something like this being too greasy, but I was pleasantly surprised that if I just used a small amount it didn't feel or look greasy. I can go multiple days in between hair washes and this product is long lasting as well.

Nice surprise
[This review was collected as part of a promotion.] I was very surprised at how well it works. At first, I thought it wasn't going to leave my hair textured or non-frizzy because it seemed too watery, but I was so happy with the results. I can come out of the shower, put it in my hair and just let it dry. My hair is able to obtain its natural curl and after it dries, I can put it up in a ponytail without the frizz. I would definitely recommend it to anyone.

Definitely brought a second one since I tried the first
[This review was collected as part of a promotion.] 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!
[This review was collected as part of a promotion.] 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.

Wanted to love it, but didn't work for me
[This review was collected as part of a promotion.] 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!
[This review was collected as part of a promotion.] 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.

Lightweight and frizz free
[This review was collected as part of a promotion.] Love how lightweight and easy this is to work into my fine hair. Also noting it doesn't weigh down my hair! It smells great and leaves me frizz free and silky!

It works!
[This review was collected as part of a promotion.] I didn't know whether this would work on my hair, as it is frizzy and wavy and porous, but after several applications, I can say it definitely does! My hair is shinier and more manageable when I use it regularly. The pump dispenser is so useful so I don't have to wrestle with a cap once my hands are slick with product. The product itself is easy to apply, although it does make my hair feel a bit heavier the first day.

I don't understand the hype
I brought it sincr my hair always frizzes up in humidity. I do have curly fine hair but I had used this product to try to eliminate the frizz and have a smooth texture once I blow dried my hair with the Dyson tools and then straightened my hair and it's still after an hour or two inhumanity it would go back up. I do like how it's lightweight and not as oily.

Summer Humidity is the Worst
[This review was collected as part of a promotion.] My hair is naturally very frizzy and wavy and is sensitive to any moisture in the air and will frizz almost instantly in humid temperatures, especially in the summer. While out working all summer, the top coat kept my hair from frizzing and having the annoying flyaways. I had to be careful how much I used as my hair could feel a bit greasy as it air-dried.

Hit or Miss Mega Sleek
[This review was collected as part of a promotion.] 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.
[This review was collected as part of a promotion.] 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.
