Anyone not wash their hair?

I know there are natural products that can be used instead of a shampoo, but using only conditioner I can't even imagine what would someone's hair look like.

 

I made shampoo by myself few times. Here are the ingredients:
¼ cup coconut milk (homemade or canned)
1/4 cup Liquid Castille Soap like Dr. Bronners
20 drops of Essential Oils of choice (I like lavender)

 

I think going off shampoo actually works really for some people, especially those with thicker or curly hair. You might go through a bit of an oily phase but then your hair will regulate itself and not produce excess oil anymore.
