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 ...

awful since formula change!
the new formula is HORRIBLE! I've used this shampoo for years and easily get 2-3 days out of each wash, the new formula has my hair greasy by the next morning. not to mention the new scent gives me a headache.
Ruined this shampoo
I'll never understand why a company will ruin a very successful long-standing product. This shampoo no longer the great hydrating lightweight giant that it was with a new formula. It's such a shame. The almost 5 star rating is going to plummet now.. I will never buy this again.
Changed formula
The new formula is terrible! Leaves my hair frizzy & dry. Plus doesnt smell as good. Will definitely not purchase again unless they change it back!
New Formula is Horrible
I have faithfully used Matrix Mega Sleek for 15+ years. This new formula is horrible. Leaves my hair feeling heavy and weighed down. The scent and look of the product looks like a shimmery body wash. The fragrance is an allergy nightmare for me. "Strong notes of Scicillian Pistachio, Salted Caramel and Vanillin" according to google. I cannot in good faith use this with known allergies (Pistachio) waiting for a reaction to occur.
I hate the new formula.
The smell makes me nauseous. I've used the matrix sleek line for 20 years. The original made my hair silky, soft and so healthy. This new stuff makes my hair feel dried out, and makes my hair tangle easily. Terrible decision to change formulas

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
