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...

WORTH the money!!
Hair Type Wavy Hair
I have wavy/curly hair, with a couple different textures and patterns throughout my head. It is lower porosity but very reactive to humidity, and I decided to test this out during the recent heat wave this week- it exceeded my expectations. I rough blow dried my hair to activate it and then finished it out by straightening in order to get pin straight hair. I have previously only used color wow dreamcoat, dreamcoat extra strength and dreamcoat for curly hair and all of them felt like i could not run my fingers through my hair and i could feel the coating. This was much easier and faster to apply and my hair still felt soft and manageable. I walked my dog in 100+ heat and humidity, worked out, and my hair still stayed straight. 10/10 worth it!! Remember it is a concentrated formula which is why it might smell bad straight in the bottle but loses the scent once its in your palm or distributed in your hair.
Works so well to smooth

[I received this product in exchange for my honest review] This heat activated top coat is amazing. It tames all frizz even in Florida heat. A little goes a long way and it makes my hair feel so healthy. Great product that will last me a while

[I received this product in exchange for my honest review] This oil is so good! Lightweight and tames frizz! Love how it smells too. Not overbearing and it fits nicely in my bag. I love all Matrix products! I would recommend this for sure

I'm in love!
Hair Type Very Curly Hair
[I received this product in exchange for my honest review] I'm very impressed with the 96H Anti-Frizz Topcoat, application is really easy. A few pumps applied to the ends of my hair and either air dry or blow dry. When my hair is dry you can absolutely see a difference compared to when I don't use it considering I have extremely frizzy and curly hair.

Definitely would buy it
