This shampoo is a lifesaver, especially for those of us battling hard water and harsh climates. Based on the power of jojoba oil and oleic acid, it cleanses well without stripping my hair, a major concern with our well water. It's a professional-grade anti-frizz shampoo that manages humidity inside ...

Love it
Really enjoyed this shampoo. I am blond (so dry hair) living in a very humid area, therefore I need all the help I can get to keep the frizz away. It does a great job and my hair comes out very smooth.
It's going to depend on your hair
Hair Type Wavy Hair
[I received this product in exchange for my honest review] So there is a lot to like about this shampoo for like 3/4 of my hair. That would be the top layer and first texture that I have. It does a fantastic job of dealing with flyaways and new growth. The challenge I'm having is the other 1/4 of my hair that is a different (more coarse and wavy bit of hair that likes to hang on to oil). That part is a challenge. Since I prefer to wash my hair every other day, this batch of hair that wants to cling to the oil in this shampoo for dear life, is driving me mad. Great product, great scent, easy to use bottle and perfect for 3/4 of my hair... It's that other 1/4 that makes me sad to sad it's not the right product for me. The product rinses great - but if your hair loves oil? May not be the right option for you either.
Okay Shampoo
Hair Type Very Curly Hair
I received this product in exchange for my honest review] Same as the conditioner, there want nothing wow about this shampoo other that it cleanse well. Given that it was made for anti frizz I didn't find the use in it for type 4B hair.
Leaves hair manageable, sleek, fragrant, and frizz-free!
Hair Type Wavy Hair
Matrix Mega Sleek Smoothing Shampoo really went far above my expectations for shampoo. I have unruly, frizzy hair that easily tangles, so it's been hard to find anything that works. My first impression when I opened the cap was that it had the most captivating, delicious scent, and I was so excited for my hair to smell that way. It has a fresh and slightly fruity scent with notes of shea butter and light citrus, like a sweet, tropical aroma, but it isn't overpowering; it's just right. This shampoo has really great slip to it, which helps detangle my wavy hair, as well as keep it hydrated and manageable while washing. It lathers up like a dream and makes my hair look so clean and fresh. It has Jojoba Oil, which locks humidity out, and Oleic Acid, which restores essential moisture...and my hair desperately needs both of those things to keep my hair from being unruly and dry. My hair feels manageable, looks sleek, smells good, and is less frizzy. Highly recommend. [I received this product in exchange for my honest review]

How does this shampoo smell
- Asked by Dyork
- Official Answer By Matrix - Brand EngageHello there! Thank you for your interest in the Mega Sleek Anti-Frizz Smoothing Shampoo. This delightful fragrance opens with bright top notes of lemon, cherry, pistachio, freesia, green apple, and pineapple greens, melting into a heart of jasmine, sugared rose petals, roasted almond, apricot, and coconut milk. It finally settles into a warm, comforting base of cedarwood, vanilla, sandalwood, salted caramel, amber, tonka bean, and warm skin musk.Was this answer helpful to you
