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 ...

Great shampoo!
Hair Type Wavy Hair
[I received this product in exchange for my honest review] I love all Matrix products so I was super excited to try out the Mega Sleek Smoothing Shampoo! This shampoo for sure has become a new favorite for so many reasons! I love how good this shampoo lathers, rinses out, smells and it leaves my hair looking/feeling amazing! Just after shampooing I can notice a difference in my hair already.. less tangled, more smooth and soft plus leaves my hair smelling good all day long! Love this shampoo paired with the conditioner and mask!



Wowza

[I received this product in exchange for my honest review] Ohh this mask does wonders, that's why it's called a supreme mask.It's very slick and absorbent, there's a lot of hydration to my face, and there is absolutely no scent. Can't go wrong with the the i'm manageability of this product

Keeps my hair looking polished
Hair Type Wavy Hair
[I received this product in exchange for my honest review] The first thing I noticed was the lather. It foams quickly without needing a ton of product. It definitely is a good cleanse before using conditioner. My hair feels noticeably softer and when I rinse it out, it doesn't leave my hair tangled. The scent is clean and not overwhelming. Where it stands out the most is the shine. My hair looks so polished after I dry it. It does a great job of taming my frizz and I don't have to work as hard with my heat tools to get my hair to do what I want it to do.

Unfortunately not for us
Hair Type Wavy Hair
[I received this product in exchange for my honest review] My daughters and I used the matrix mega shampoo, conditioner and mask. The smell and texture are great. After using it for a while our hair started to be one dry and damaged feeling. Unfortunately this product isn't for us.


Loveeeee
Hair Type Straight Hair
I would highly recommend this product especially for the girlies with straight fine hair. It didn't weigh my hair down. It made it shinier and move voluminous. I have long straight fine hair for reference. It also smells really good!!

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
