Totally sold to Marcel's bars ;-)
* completely zero waste
* very nice scents: this one has the wonderful combination scent of vanilla with cherry blossom!
* 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 cherry blossom provides the fresh hue and the vanilla has a soothing effect.
I really can't think of any cons to these shampoo bars.
