It seems more complicated than it is, but it is very easy to use both shampoo and solid conditioner. Follow these steps:
Solid shampoo:
Wet your hair.
Apply in circles to create lather.
Rinse until all the product is removed.
Solid conditioner:
Apply in circles from medium to ends.
Let it act for 3 minutes.
Make sure to remove all of the product.
Solid product care:
Place them on a base where they can dry and that will not come in contact with water.
Clever!
