Totally sold to Marcel's bars ;-)

Why:

* completely zero waste
* vegan
* very nice scents: this one has the wonderful combination scent of tonga and muguet!
* 1 bar is approximately equal to 3 bottles, so very economical
* cheaper than plastic bottles
* sulphate free

This shampoo bar contains Argan oil to make/keep the hair shiny.
The South American tonga bean scent creates a floating, dreamy effect. This combines the shampoo bar with the fresh scent of muguet flowers. Perfect to end up in a dream world.

I really can't think of any cons to these shampoo bars.
