This conditioner is aimed at people with coarse, colour-treated hair specifically — Wella sells separate INVIGO Brilliance formulas for fine/normal hair, so this one is not the right pick for finer textures, where it may feel heavy.

It's a professional colour-care product typically sold through salons and pro retailers, but the use itself (rinse-out, after shampoo) is straightforward enough for home use by both men and women.

Where a generic conditioner just softens hair, this one is built around slowing the specific chemistry that fades hair colour — histidine and vitamin E are included to interrupt oxidation, and copper-encapsulating molecules are meant to help colour pigment stay put — while the fatty-alcohol base is weighted toward coarse hair's higher conditioning needs rather than a one-size-fits-all formula.

• Shampoo hair first, then blot out excess water
• Apply the conditioner to damp hair, concentrating on mid-lengths and ends rather than the scalp
• Leave on for one to two minutes
• Rinse thoroughly
• For best results, pair with the matching INVIGO Brilliance shampoo for coarse hair

Pros

• Formulated specifically for coarse texture, using richer fatty-alcohol conditioning agents than a fine-hair conditioner would use
• Histidine and vitamin E are included to slow the oxidation process that causes colour to fade after a salon service
• Copper-encapsulating technology in the Brilliance-Blend is designed to help hold colour molecules in place rather than just coating the hair

Cons

• Contains methylparaben and propylparaben, preservatives some colour-treated-hair shoppers specifically try to avoid
• Too rich/heavy for fine or normal hair — Wella makes a separate formula for those textures
• Colour-protection benefit is preventive (slows fade) rather than a treatment that restores already-faded colour
