For anyone with color-treated hair — any hair type, length, or gender — who wants to slow fade and keep color looking fresh between salon visits. Not formulated as a purple/toning shampoo (that's a different Matrix product), so it won't correct brassiness on its own; it's a maintenance shampoo for color vibrancy and shine generally.

What sets this apart from a generic "for colored hair" shampoo is the antioxidant framing: color fades partly from UV and environmental oxidative stress, not just from washing, and sunflower seed oil plus tocopherol are included specifically to counter that rather than just moisturize. Combined with a cleansing base that isn't overly stripping, the goal is to clean hair and scalp normally while giving color a defensive layer against everyday exposure.

It's also positioned as a system product — Matrix's own testing and marketing tie the "up to 32 washes" figure to using this shampoo with its matching conditioner, so the fullest benefit comes from using both rather than the shampoo in isolation.

Apply to damp hair

• Work into a lather across the scalp and lengths
• Rinse thoroughly
• Follow with Color Obsessed Conditioner for the full antioxidant color-protection system

Pros

• Antioxidant pairing (sunflower seed oil + tocopherol) targets oxidative color fade specifically, not just generic buildup
• Brand-verified color protection of up to 32 washes when paired with the matching conditioner
• Dimethicone adds shine and smoothness without noticeable heaviness
• Vegan formula

Cons

• Uses sodium laureth sulfate, a stronger cleansing surfactant some color-conscious users try to avoid
• The 32-wash figure is for the shampoo-and-conditioner system, not the shampoo alone
• Not silicone-free, so fine or buildup-prone hair may need an occasional clarifying wash
