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 ...

My hair has only looked this good after a salon visit. I have naturally wavy, frizzy dry hair. I came across this procuct as samples in my order. Even in high humidity my hair looked sleek and fabulous. I ended up ordering full size in this line.
Hydrating Shampoo — Highly Recommend!
Hair Type Wavy Hair
[I received this product in exchange for my honest review] This hydrating smoothing shampoo from Matrix has been a great addition to my shower routine. I've used it with the matching conditioner and conditioning mask and my hair has never felt healthier. My hair feels soft, hydrated, and healthy. I highly recommend trying it if you've been looking for hydrating hair care. I love the squeeze bottle design too. It's easy to dispense the right amount. The shampoo itself is easy to apply, lathers well, and rinses out easily.
New formulation…not good!
Hair Type Wavy Hair
I have been using this shampoo and conditioner for a long time. I saw that the large bottles were on sale and couldn't miss out. As soon as I squeezed it out of the bottle I knew something was wrong. It was a different color and smell. Matrix has changed the formulation…and not for the better. My hair feels brittle and is frizzy. Whatever they did was not a good change. I'm very disappointed and now I'm stuck with a huge bottle.
Clean and moisturized
Hair Type Wavy Hair
[I received this product in exchange for my honest review] I've been using this shampoo along with the smoothing conditioner. It does a great job of thoroughly cleaning yet keeping hair moisturized. I have wavy hair, and usually after washing, my hair becomes one giant frizzball. I've noticed a reduction in frizz after washing, but I especially notice a difference the next day. My hair looks shinier and smoother. The shampoo has a nice citrusy scent. I have confused the shampoo and conditioner bottles more than once, so it might be good to differentiate them a bit more.
1.7 oz Travel Size bottles is not the this shampoo
I have used Matrix sleek and smoothing shampoo for many years and recently bought the 1.7 oz travel size to take on a work conference trip and the shampoo that was in the bottle is not the same shampoo. This review for the Travel Size Only!

- Q
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
