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 ...

Best shampoo ever!
Hair Type Straight Hair
[I received this product in exchange for my honest review] The best shampoo I have ever used! I had been struggling lately with my dry scalp it would get very flaky and I have tried many things to fix it but this shampoo is a game changer it hydrates my hair very well which has prevented my scalp from flaking the shampoo also smells so good it smells very fresh and clean but also sweet which I really enjoy. I would definitely recommend overall but especially if you are struggling with a dry scalp as I have noticed a tremendous difference.
Love this line!
Hair Type Wavy Hair
[I received this product in exchange for my honest review] I really like this shampoo but for the amount of product I put in my hair in the summer I feel like you definitely need to double wash and use a clarifying shampoo first if you have wavy or curly hair! Other than that I love the scent and consistency and I think the line all together has kept my hair so smooth!
Worth the hype. Well behaved hair finally!
Hair Type Straight Hair
[I received this product in exchange for my honest review] I am shocked how much I like this shampoo. I have stubborn coarse, blonde hair that loves to snag and knot. This shampoo plus conditioner made my hair have so much volume but also so few snags in the morning! The scent is lovely, beachy without being cloying. It washed my hair clean and seems to be a good value for the price. I get the hype and will use again!

Hair Type Wavy Hair
I received this product in exchange for my honest opinion. I've experienced hair problems for awhile now and finding the right products for my hair is hard. This one has worked wonders I always do 2 cleanses for my hair & by the next day it looks nasty. But this product totally helped with the longevity of my hair overall. I like that it doesn't fell heavy on the scalp and it father's up really well & a little goes along way. Overall its a wonderful product & I highly recommend to anyone looking for a good hair care line.
Great shampoo!
[I received this product in exchange for my honest review] I was pretty pumped to try this matrix shampoo.Despite the horrible, bright orange color of the bottle (and really the rest of the bottle design is horrible too--so many fonts and colors and directions). Plus the bottles are printed different directions. They get half a point for having the conditioner be the bottle that opens upside down so it doesn't pour out when you flip the lid, because it's a thicker product, I'll give them that, but since the design of the bottle is not really the most important thing here, I do love the shampoo. It smells absolutely glorious. It's a smooth clean shampoo despite not having any sulfates. it rinses so easily and quickly, and a little goes a long way so this bottle will last a really long time. Plus there is an entire system with a conditioner and masque so you can make sure all your products are working together!

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
