Permanent color. PHYTO's expert colourists have created the first ammonia-free, permanent hair color with botanical pigments that combines color performance with beautiful hair and a gentle action on the scalp. Enriched with a unique blend of botanical pigments derived from five dye plants, selected for their superior pigmenting properties. Their high concentration in the pigment base ? up to 74%, depending on the shade ? ensures an intense, natural color with radiant nuanced highlights that acts as a shine booster and does not fade. 100% of grey hair is covered from the first application.
