Rhassoul Clay
What Is It?
Rhassoul clay, also known as Ghassoul clay, is a mineral-rich, natural clay sourced from the Atlas Mountains of Morocco. It has been used for centuries in skincare and haircare due to its exceptional ability to absorb impurities, remove excess oil, and soften the skin. It is particularly beneficial for oily, acne-prone, and combination skin types, as well as for detoxifying the scalp and hair.
