Solid Shampoo
Solid shampoo belongs to the starter pack of zero waste beauty routine. The reason why you should start using solid shampoo is that most conventional shampoos contain chemical ingredients that harm the environment and also dry out your scalp and leave it sensitive and irritated. Solid shampoo on the other hand is made out of 100% organic and natural ingredients, it will also nourish the scalp making your hair strong and healthy.
When using the solid shampoo, you should wet your hair first, then apply the solide shampoo directly on your head or rub into your palm first to create a foam, then spread the product around.
Notice, the dry shampoo, should be conserved in a dry place with room temperature!
