Purple pigment neutralises yellow — colour physics, not magic.
Brassiness in bleached and grey hair is neutralised optically by purple pigment. The Anti-Yellow line — toning shampoo, balm and mask — keeps a cool tone at home between salon visits.
1–2 times a week, alternating with a regular sulfate-free shampoo.
Yes — grey hair yellows too, and purple pigment restores a clean cool tone.
