What does Senna Cassia do?Updated 23 days ago

Senna/Cassia forms a shiny, colorless protective layer around your hair. It is therefore particularly suitable for fine, limp, or particularly damaged hair.

It is mixed with warm water at 60°C and left on for about 15 minutes.

If you leave Senna/Cassia on for longer, a golden shimmer may appear, as the powder has its own color. If left on for a significantly longer period of time, the shimmer may settle into the hair a little, but it will wash out again with the next shampoo.

As it has a protective effect and fills in any gaps in the hair's cuticle layer, we recommend using it as a pre-treatment before applying natural  hair dye to chemically pre-treated hair.
