Rhassoul clay, also known as Moroccan lava clay, has been used in beauty and skincare routines for hundreds of years. Sourced from the Atlas Mountains in Morocco, this naturally occurring clay is chock full of rich minerals with cleansing and rejuvenating effects. For skincare and beauty, Rhassoul clay offers a versatile and all-natural ingredient option that supports clean beauty goals and DIY hair and skin formulas.

What Is Rhassoul Clay?

Sought for its cleansing and soothing abilities, Rhassoul is a mineral-rich clay that's formed by volcanoes. It's a proven all-natural exfoliate often added to hair and skincare routines.

Plus, it's great for sensitive scalps and for those who adopt a less-is-more approach to their skincare products. It has a reddish-brown color due to its natural blend of minerals, including silica, magnesium, iron oxide, potassium, and calcium. 

Reported Benefits of Rhassoul Clay for Hair

Gently Cleanses the Scalp
For hair care, Rhassoul clay acts as a gentle cleanser. It helps remove excess oils and build-up and is ideal for those who prefer a no-shampoo care routine. Some of the best Rhassoul clay benefits for hair care are that it removes impurities, adds volume, and leaves your hair with a luxurious sheen. 

May Help With Oil and Build-up
Rhassoul clay is naturally absorbent. That's why it's useful for treating oily scalps and removing residue from other products. Use Rhassoul clay for a cleaner, lighter feel to your hair, especially when used regularly. 

Enhance Curl Definition and Volume
With the right touch, curly hair thrives when treated with Rhassoul clay. Don't tame your hair. Embrace its natural voluminous state with Rhassoul clay. 

Rich in Minerals That Support Scalp Health
Silica and magnesium are scientifically proven to support hair and scalps. The NIH has conducted multiple studies that analyze the impacts of magnesium on health and silica for skin and hair care. That's one of the many reasons Rhassoul clay is a must-have for DIY creators and people with a passion for natural beauty.   

How to Use Rhassoul Clay in Hair Care

As a Shampoo
Rhassoul clay can be used as the base for a gentle, no-shampoo hair care routine. A basic, accessible formula includes:
  • 2 tablespoons Rhassoul clay
  • Enough warm water (or aloe vera juice) to create a smooth paste
  • Optional: a few drops of essential oil suitable for the scalp, such as rosemary or tea tree
Apply to damp hair and massage gently into the scalp. Let sit for 2–3 minutes before rinsing thoroughly. Due to its absorbent nature, it's typically used weekly or as needed to manage build-up.

As a Hair Mask or Rinse
For a deeper cleanse, Rhassoul clay can be applied as a thicker mask. Leave on for 5–10 minutes. This method is used to refresh and cleanse the scalp between styling and before conditioning.

Tailored for Different Hair Types
Beauty professionals often adjust Rhassoul clay blends depending on hair type. Those with curly or coily hair may benefit from mixing the clay with moisturizing oils, while individuals with fine or oily hair tend to use more water-based recipes. As always, patch testing and small batch trials are recommended before broader use.

How Often Can Rhassoul Clay Be Used on Hair?

Frequency depends on individual hair needs. Generally, it's used once per week on oily hair or biweekly to monthly on normal to dry types. People with sensitive scalps may wish to start with limited exposure and adjust based on personal results.

Please note that Rhassoul clay is not a leave-in treatment and should be washed out after 30-50 minutes, depending on hair type. This allows time for the minerals in Rhassoul clay to naturally absorb oil and debris from your hair while leaving you with a lighter, cleaner feeling.

Potential Side Effects and Considerations

Rhassoul clay is considered safe for cosmetic use when handled properly, but a few considerations apply:
  • It may cause dryness if overused, especially on low-porosity or chemically treated hair.
  • Residue can occur if not rinsed thoroughly. Rinse with care using warm, filtered water if possible.
  • As with any new ingredient, you should perform a patch test before full application.
Scientific research on Rhassoul clay is limited. However, the main ingredients in Rhassoul clay, namely silica, magnesium, iron oxide, potassium, and calcium, are, in healthy amounts, popular additions to most health and beauty routines. Plus, Rhassoul clay has been used for its beautifying and rejuvenating effects for centuries. 

Considerations for Small-Batch Makers

Rhassoul clay can be mixed into powder-based or pre-mixed hair products, offering flexibility for different product lines. Consider pairing it with aloe powder, essential oils, or carrier oils to enhance the product's feel and application. Packaging should be airtight to preserve texture and moisture levels.
