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 ...

Good shampoo but didn't wow me
Hair Type Straight Hair
[I received this product in exchange for my honest review] It lathers well and it did leave my hair not so dry/coarse-feeling after rinsing. I can't speak on how it feels on the scalp since I have seborrheic dermatitis so I didn't apply it on the scalp. I honestly didn't feel like it did much for my hair other than it wasn't as drying as most shampoos are but imo I can always follow up with a good conditioner to really counteract the dryness.
A smoothing shampoo that reduces frizz, adds shine, and leav
Hair Type Wavy Hair
[I received this product in exchange for my honest review] I've been impressed with this shampoo so far. It lathers well, rinses clean, and leaves my hair feeling soft without drying it out. I noticed more shine and less frizz after using it, and it helps my hair feel smoother and easier to style. It cleans thoroughly without feeling harsh.
Frizz tamer
Hair Type Wavy Hair
[I received this product in exchange for my honest review] This shampoo from Matrix really helped my frizzy hair. I really noticed a positive change with dandruff too. The shampoo lathers great with just a small amount, and smells wonderful too. It rinses easily and I am able to go a couple days without washing it again because it leaves the hair feeling fresh and less products is needed for frizz.
Rich Lather + Smells Fantastic!
[I received this product in exchange for my honest review.] This shampoo lathers extremely well and doesn't dry out my scalp at all. It smells amazing (this whole line does) and I'm fairly confident this bottle is going to last me a while. I don't know if it has any true effect on calming any frizz, however.
Switching to this shampoo
Hair Type Wavy Hair
[I received this product in exchange for my honest review] Another repurchase for me. Love the smell, reminds me of sol de Janeiro and will be repurchasing. Leaves my hair feeling smooth and hydrated. Used daily and the none of this line makes my hair feeling greasy or weighed down.

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
