Our verdict

A sulfate free smoothing shampoo for frizzy hair that is color safe and comes in a large bottle. The headline frizz claims depend on using the whole Mega Sleek system, not this shampoo alone.

Overview

A sulfate-free cleansing base with jojoba oil washes MATRIX Mega Sleek through the hair without stripping it, preparing strands to take in moisture. The shampoo is the first step of a smoothing system aimed at frizzy hair.

Frizz control in humid weather is what this shampoo is designed for, with a gentle wash that suits colored hair. Its strongest claims are tied to the full system, so buying the shampoo alone delivers only part of the effect.

Who it's for

Humid summers and hair that puffs up after washing are where a smoothing shampoo helps, especially with the matching products. People with flat, fine hair who want lift will find smoothing formulas weigh them down.

Pros and cons

Pros
  • Sulfate free wash
  • Safe for color treated hair
  • Jojoba oil for smoothing
  • Large salon size bottle
Cons
  • Frizz claims rely on the full system
  • Gourmand scent will not suit everyone
  • Specs list an active that bullets omit

Performance notes

Frizz comes from a raised cuticle pulling in moisture from the air, so a gentle, oil infused wash that leaves the cuticle flatter reduces it. The effect lasts longer when the conditioner and styling steps follow, since the shampoo alone mostly cleans and preps.
