The mask and the shampoo declare the same violet dye — the difference is what carries it. A straight comparison, with the times and prices each listing actually publishes.

Two purple bottles, near-identical names. Fanola says both tone the same, so the decision comes down to price, published leave-on time and how the hair feels afterwards.

Green pigment cancels red, and Fanola No Red is the green shampoo on this site. Here is what is really in it, who it suits, and the situations where it is the wrong bottle.

Blue sits opposite orange on the colour wheel, so a no orange shampoo cancels copper tones by adding pigment rather than removing anything. What that means in practice, what it cannot fix, and which Fanola Wonder No Orange product to start with.

Almost every purple shampoo on the shelf carries the same violet dye. What matters is how much of it is in the bottle, and what that pigment can and cannot do once it is on your hair.

Violet does not remove yellow from your hair. It adds a second pigment on top of it, which is why toning is maintenance rather than correction, and why it washes out.
