Rhassoul vs Bentonite Clay

Rhassoul Clay Bentonite Clay
Ingredients Clay found in the Atlas Mts. High percentage of silica, magnesium, potassium, and calcium


Volcanic ash sediments, has a high percentage of silica and iron
Uses Detox, face mask, skin treatment, cleanser, conditioner


Detox, face mask, skin treatment, cleanser
Slip (1: terrible – 5 great) 5

Nothing makes detangling as easy as rhassoul clay. My curls come out defined, smooth and clumped



My hair wasn’t as easy to comb through

Softness 5

Gives me HIH syndrome


My hair was soft after, but I still felt I had to follow-up with a conditioner, as it wasn’t as soft as I’d like it to be.


Preparation 4.5

Water, a little aloe or vinegar, mix and apply. Although my mix is always slightly runnier than I’d like.



This was very awkward to mix, the clay swells up as soon as water hits it and the mixture was really thick.

Appearance of hair 5

This always gives me a nice healthy shine


My hair looked very clean and shiny, although on the 3rd day it looked a little waxy to me.


Would I recommend this for low porosity hair Definitely, this stuff is golden! In my low porosity holy grail products I’d recommend it for an occasional hair cleanse/detox, but I don’t think I’ll add this to my list of low porosity must-haves.

Upcoming Post: Bentonite Clay


I finally got my hands on some bentonite clay. Many readers have asked my opinion on it and now I’ll finally be able to give it. I’ll be reporting my results and doing a comparison on rhassoul and bentonite clays later on this week. In the meantime, I’m washing my hair for the second time this week— what?? This is a rare occurrence for me, but I couldn’t wait to try the clay.

Do you prefer rhassoul or bentonite?

Reader Question: Bentonite Clay

Recently, I received this question from a subscriber: “What do you think about using Bentonite on your low porosity hair?  What suggestions do you have?”

I have heard rave reviews on bentonite clay. I’ve yet to try it, but do plan on testing it out in the near future. When I do, I’ll be sure to write a review.

Bentonite clay is derived from volcanic ash. It has a PH of about 8.3-9.1. It is made of (from Mountainroseherbs.com):

Silica- 61.4%
Aluminum- 18.1%
Iron- 3.5%
Sodium- 2.3%
Magnesium- 1.7%
Calcium- 0.04%
Titanium- 0.02%
Potassium- 0.01%
Moisture- 7.8%

Like many clays, bentonite clay is known for its absorbent properties. The clay, once mixed with water and applied to hair, is supposed to pull toxins from the hair. Like rhassoul, bentonite has a negative ionic charge.

I’m not a scientist, but here’s my explanation of ionic charge. Ions are atoms or molecules that have lost or gained an electron (-), which carry a negative charge. Positive ions have lost an electron and negative ions have gained an electron. Molecules are constantly seeking balance. Thus, if an ion has an extra electron it will try to balance this by taking an extra molecule from the surrounding environment (e.g. hair), or by losing its extra electron.

From Braun.com: “positive ions are created through friction – like brushing your hair. They repel each other – making your hair static, frizzy and dull-looking. Negatively charged ions are attracted by positively charged ones, immediately neutralizing them and leaving your hair static and frizz-free.”

As mentioned in an earlier post, products with a positive ionic charge  tend to give the hair a more compact structure. Acidic products (aloe, vinegar, many conditioners) are positively charged, while alkaline products (rhassoul clay, bentonite clay, Terressentials hair wash) are negatively charged.

Based on this information and some rave reviews on the web from other low porosity naturals, I believe that bentonite clay should work on low porosity hair as well.

Again, I’ve never tried it, but when I do try it in the future, I’ll be sure to post results.

In the meantime, here is a short and nice video review on bentonite DIY mudwash: https://www.youtube.com/watch?v=yCQhSOGLAwU

Have you tried bentonite clay? What were your results?

Remember, never mix clays with metal spoons or in metal bowls.
