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 ...

Anti-Frizz Shampoo
Hair Type Wavy Hair
I received this product in exchange of my honest review. I love the smell of the Matrix Mega Sleek Smoothing Shampoo. I use this daily with Matrix Mega Sleek Smoothing conditioner. Makes my hair smooth and manageable. Shiny and easy to style. No frizzy hair.
Obsessed! Leaves hair smooth and detangled and clean
Hair Type Wavy Hair
[I received this product in exchange for my honest review] I really love this line of hair products so much and the shampoo really delivers!! I have wavy hair that can sometimes feel tangled and dry, even in the shower. Unlike many other shampoos, this one actually seemed to hydrated my entire head of hair like a conditioner! Hair was smooth and shiny after. Im now a convert to Matrix but will need to buy a bigger bottle next time as this size wont last long enough.
Great For Tangly, Frizzy Hair
Hair Type Straight Hair
I received this product in exchange for my honest review and I absolutely love this line from Matrix! My hair has never felt so soft and non tangled before when waking up in the morning. The scent on top of it is really good and not too strong. It does a great job at cleaning but the only thing I didn't like was how flimsy the bottle was. I dropped it once and the top flew off so now I can't close it. Besides that, I love the product inside!
Lathers great, smoother hair
Hair Type Wavy Hair
[I received this product in exchange for my honest review] The Mega Sleek Smoothing Shampoo lathers nicely and smells great. My hair feels so clean after using it, and after using the conditioner and mask that are a part of this system, it feels softer and silkier. We haven't had many humid days, so I'm not sure about that, but my hair looks smoother after using it.

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
