Rhassoul Clay — Mineral-Rich Detoxifying Clay for Deep Cleansing, Oil Control & Scalp Purification Systems

Rhassoul Clay (also known as Moroccan Lava Clay or Ghassoul Clay) is a naturally occurring mineral clay sourced exclusively from the Atlas Mountains of Morocco. Traditionally used for over a thousand years across North African and Middle Eastern beauty rituals, it remains one of the most respected ingredients in spa and cosmetic formulations.

Rich in silica, magnesium, potassium, and calcium, Rhassoul Clay is valued for its ability to deeply cleanse, absorb impurities, and refine both skin and hair without excessive dryness.

Unlike more aggressive clays, Rhassoul offers a unique balance of detoxification, mild exfoliation, and conditioning, making it suitable for both skin and hair applications.

At Skin Foodie, Rhassoul Clay is positioned as a high-performance mineral detoxifier for formulators looking to create deep-cleansing systems that purify without stripping the skin or hair.
