I used my own shed hair (natural, African , 4c if you are into hair typing) and imaged it:
-on its own without any washing
- washed with shampoo only (2 minute water rinse, 2 minute shampoo wash, 2 minute water rinse and air dried for 4 hours)
-washed with cleanser only ( 2 minute water rinse, 2 minute cleanser), 2 minute water rinse and air dried for 4 hours)
-cleansers with extra time 10 minutes instead of 2 minutes - ACV, baking soda shikakai
Quick Cleansing Results
|Ability of Hair Cleansers to Remove Oil from Hair |
|Best Cleansers (Complete visible oil removal)||Good Cleansers (vast majority of oil removed)||Worst Cleansers (little to no oil removal)|
|Shampoo||Hair Conditioner||Baking soda|
|Oat water||Castile soap (diluted)||Shikakai|
|Natural soap/shampoo bar||Bentonite Clay||Apple Cider Vinegar|
1. The Controls - Oily Hair (Dirty/Oily Reference) and Shampooed Hair (Clean Reference)
The controls let you have a baseline of what the hair looks like prior to washing and what it looks like with a proper wash. You can therefore judge the clay washes in context of dirty and clean hair.
|Oily natural hair|
|Clean shampooed natural hair|
2. Hair conditioner only - Result: Mostly Clean Hair
3. Oat water- Result: Clean Hair
4. Castile soap - Result Mostly Clean Hair
5. Natural soap - shampoo bar - Result: Clean Hair
6. Baking soda - Result: Hair still oily
Many naturals tout baking soda as a natural cleanser but in my experiment, it really did not cleanse at all. The hair was extremely oily even after a 10 minute soak and rub.
7. Bentonite clay - Result: Mostly Clean Hair
8. Rhassoul clay - Result: Mostly Clean Hair
9. Shikakai- Result: Hair still oily
10. Apple cider vinegar- Result: Hair still oily
Some naturals do promote apple cider vinegar as a natural cleanser. It did however produce the worst result of all the cleansers. The hair actually looked oilier than when it started despite prolonging the cleansing time. It did not cleanse the hair at all in this experiment.
Hair conditioner - L'oreal Eversleek Smoothing Conditioner, Shampoo - Johnson and Johnson baby shampoo, Oats - Quaker Oats, Baking Soda - Sainsbury's, Shikakai - Hesh, Apple Cider Vinegar - Sainsbury's, Bentonite and Rhassoul Clay - Sheabutter Cottage, Castile soap - Dr. Bronners, Natural Soap - Mother in Law made it.
Please do note that under the microscope we can see oil layers but we do not see small deposits on hair e.g hair conditioner deposits (well you actually could see them with specialised instruments but not with my microscope!). Strictly speaking this experiment will answer the question, how well will washing method X remove oil from hair.
