About

A direct hair-dye ingredient with more irritation uncertainty than a standard skin-conditioning ingredient.

This is a specialty hair-color ingredient rather than a general skincare active. Hair dyes as a class deserve more caution than bland emollients because local irritation, sensitization, and limited public toxicology depth for niche colorants are realistic concerns even when no explicit restriction is listed here.

Function

HAIR DYEING

Known concerns

  • Hair dye ingredients can trigger irritation or allergy
  • Limited public data for this specific colorant
