People with lightened, highlighted, or bleached brunette/brown-based hair that has developed brassy or orange undertones, who want a rinse-out corrective treatment rather than a daily conditioner. Suitable for at-home consumer use; gloves recommended to avoid staining hands.

Its violet pigment is chosen specifically to sit opposite orange/brass on the color wheel, so it corrects warmth in bleached or lightened brunette hair within a normal conditioning step, rather than requiring a separate toning product or a salon visit.

After shampooing, apply to wet hair (gloves recommended to avoid staining skin). Leave on for 5 to 10 minutes, shorter for a subtle refresh, longer for maximum neutralization, then rinse thoroughly. Avoid daily use due to concentrated pigment level.

Pros: violet pigment directly counteracts orange/brass tones through color theory rather than just masking odor or adding shine; conditions with mineral oil and soybean oil while toning in the same step. Cons: same concentrated pigment can leave hair looking dull or overly violet-tinted if overused or left on too long; mineral oil can build up with repeated use; not a substitute for a daily conditioner since brand advises against daily use.
