Violet Crush Purple Toning Mask

Many reviewers say the mask effectively corrects brassy, yellow or orange tones, leaving blonde hair looking brighter or ash-toned.

The most common praise theme across the 250-review corpus (4.4 average, 92% would recommend).

Several reviewers praise the mask for leaving hair feeling soft and conditioned with a pleasant scent, beyond just the toning effect.

Recurring secondary praise alongside the toning-effectiveness theme.

At least one reviewer warns that leaving the mask on too long can tint hair purple, taking over a week to fully fade.

One reviewer reported their hair actually turned purple and said they would not use the product again for that reason; the AI summary echoes a general staining caution.

Some reviewers report minimal to no visible toning effect, saying their blonde looked virtually unchanged after use despite the hair feeling soft.

A minority theme noted both in the AI review summary and in an individual low-rated review.

A portion of reviewers found the mask drying, with some recommending a follow-up moisturizing conditioner to compensate.

Noted in the site's AI review summary as a recurring minority complaint.

How this page was made

  • This page is assembled from the same researched records the individual product pages render: identity, each ingredient list as printed, each brand's own claims, dated price observations, and review themes written in our researchers' own words. Nothing on it is written per comparison.
  • We do not rank these against each other. Which of them suits you depends on your hair, and that is what the consultation works out.
  • The formula similarity percentage is a stored, precomputed number: position-weighted overlap of the two ingredient lists blended with agreement on the attributes we derive. It measures how alike two formulas are, not how well either works.
  • The value band is a fixed label over two stored numbers: this product’s cost per ounce as a percentile of every product of this type we have priced, each at the size it is most often sold in, and how many products we score as doing the same job cost at least a quarter less per ounce.
  • The "Is this right for you?" panel reads only your own consultation answers, and it applies exactly the filters our recommendation engine applies. It is computed when you load the page and is never stored on it.
  • 9 sources were consulted across the products on this page.
  • Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice. We do not sell these products and take no placement fees.
  • This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
