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...

Does not smell the best
Not sure if I had gotten a bad batch even possibly … had a very weird almost fishy smell. I love the shampoo and conditioner mega sleek and the smell of them but was not a fan of this !! I had to return.
New formula stinks… literally!
There is a new formula and it smells bad and does not work as well as the formula. I've been using for over 10 years. I need to find something new. There's no way I will continue using this product.
Incredible
This stuff is amazing. I have dry, color-treated hair. I use the mega sleek before I blow dry, and it makes my hair incredibly soft and shiny. It does have a slight fishy smell, so you have to shake it well before use. I have never noticed the smell on my actual hair, just in my palm before I use it. This is my favorite hair product!
Magic in a bottle
This works amazing! Yes initial fishy smell but it goes away once you put on your hair! And honestly after that, hair smells amazing!! So the fishy smell does not linger at all
The smell…
It's works pretty good…But smells absolutely like cat pee. I'm not sure I'll be able to get over the smell.
