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 ...

[I received this product in exchange for my honest review] This shampoo leaves my hair feeling soft, smooth, and shiny after every wash. It provides great hydration without weighing my hair down, and the fresh scent is a nice bonus. My hair feels healthier, more manageable, and easier to style. Overall, it's a great option if you're looking for a nourishing everyday shampoo.
Bring back the old formula PLEASE!
I wrote a review on the conditioner as well, but the shampoo is my biggest disappointment. I have used this set for years now. I would recommend it to anyone who would listen. I have tried this new formula for about a month now and I leave every shower feeling sad i have to look for a new shampoo. As time goes on, my hair gets worse and worse with this new formula. Its dry and tangled. I feel eeceived with the complete change of formula while keeping the same name on your product. This is not the same shampoo and I am so sad about it. I am begging you all to please please please bring back the old formula. We've loved you for years, please don't let us down now!
Matrix has a Smooth Brain
After using the original formula for over six years, my hair had been glorious! I never received any compliments on anything other than my hair. The shine and softness it gave me was amazing. But then, the brand had to cheapen their reputation and change the formula. Now my hair is dry, tangled, and dull. It's hard to take care of when wet, as it becomes knotted in the shower, and it's even harder to work with when dry. The texture of my hair has changed and it feels and looks disgusting. I'm so disappointed by this brand. When I reached out to them they said they could only refund me if I send back my product with my receipt and stated the reason why, all within the 4 weeks of the purchase. FREAKS! I've been using the shampoo and conditioner for OVER four weeks!! That's what happens when you try a shampoo!!! I was hoping something would change!! It did, but for the worst. I'm truly appalled by their actions and decision to change this line; I have turned so many people on this brand in general and this combo specifically, just for them to become cheap and ruin what they once had.
It's ok
Hair Type Very Curly Hair
[I received this product in exchange for my honest review] Smelled good and left hair clean without overly drying. A little went a long way and it rinsed out of my hair well. It was an ok shampoo to use when I just needed something without a ton of fuss.
AMAZING

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
