Question for castor oil users
I was reading an article on here about castor oil because I wanted to know what was so great about it. It's the oil i hear the most about from natural next to evoo... It said it caused build up that could only be removed by shampoo.. This seems wierd to me since most of us try to aviod shampoo or shampoo with sulfates.. Has anyone noticed this build up when using castor oil? Also could you include what brand you use in your response maybe it makes a difference..
