Is Brilliant Black safe for sensitive scalps or color-treated hair?

The dye contains ammonia and PPD, which can irritate a sensitive scalp or interact with previously colored hair; a 48-hour patch test is strongly recommended, and anyone with a known PPD allergy should avoid it.

What is the function of para-phenylenediamine in Brilliant Black hair dye?

Para-phenylenediamine acts as a primary intermediate that, after oxidation by peroxide, forms large black pigment molecules that bond to the hair cortex, creating the deep shade.

How often should Brilliant Black be applied and does it contain any controversial ingredients?

Brilliant Black is a permanent color intended for reapplication every 4 to 6 weeks to maintain shade, and it includes ammonia and PPD, ingredients common in permanent dyes but flagged for potential irritation and regulated for safety.
