Matrix Shampoo Lineup Reviewed (Brass Off, Mega Sleek & More)

Matrix (owned by L’Oréal, sibling brand to Biolage) is a professional haircare line sold both in salons and at accessible retail. Its Total Results range covers several distinct concerns under one brand name — worth knowing which specific product actually matches your situation rather than assuming “Matrix” means one formula.

Brass Off: the blue toning shampoo

Total Results Brass Off is a color-depositing blue-violet shampoo formulated to neutralize brassy, orange tones in lightened brunette hair. It’s sulfate-based (sodium laureth and lauryl sulfate) with amodimethicone for smoothness, and it’s meant for occasional, targeted toning use rather than a daily driver — leaving it on for a couple of minutes is generally how brands recommend maximizing the toning effect.

Mega Sleek: the frizz-control shampoo

Total Results Mega Sleek is a different product entirely — a smoothing, shea-butter-based shampoo aimed at frizz control and manageability for unruly or coarse hair, also sulfate-based, with dimethicone included for shine and frizz reduction. It’s suitable for color-treated, damaged, or natural hair, but it’s formulated for smoothing rather than volume, so it’s a poor match if your priority is lift for fine, flat hair — see our volumizing shampoo guide for that goal instead.

What “Matrix conditioner shampoo” searches are usually looking for

This ambiguous search term most often reflects people looking for a specific Total Results shampoo-and-conditioner pairing (like Brass Off or Mega Sleek’s matching conditioner) rather than a single 2-in-1 product. Matrix’s system logic works the same way covered in our thickening shampoo and conditioner guide: match the shampoo and conditioner from the same line, and apply conditioner from mid-length to ends only if volume or root lift matters to you.

The throughline across the Matrix range

Matrix formulas are generally sulfate-based, well-formulated for their specific stated purpose, and priced as accessible-professional rather than premium salon-exclusive. The brand’s strength is genuinely targeted formulas for specific concerns rather than one universal shampoo — check that the specific Total Results variant you’re buying actually matches your goal.
