About

A direct hair colorant with a more concerning profile than ordinary cosmetic dyes or skincare ingredients.

HC YELLOW NO. 18 is a synthetic hair colorant used for deposit colour rather than skin care. Direct dyes are reviewed closely because many can irritate skin or trigger allergy, and they offer little skin benefit beyond coloring performance. That makes a middling safety score more appropriate than a high one.

Known concerns

  • Hair colorants can trigger irritation or allergy
