This solid 2-in-1 shampoo and conditioner is suitable for all hair types. The contained organic lemon oil with its fresh, fruity scent puts you in a good mood, and the organic jojoba oil and organic sea buckthorn pulp oil take care of the scalp and soft, smooth hair. Solid shampoo, also called solid shampoo or solid shampoo, is not hair soap, but actually shampoo, but not in liquid form. It contains mild surfactants and is also suitable for waters with high hardness (important if you have problems with hair soap).
