NO it doesnt matter if its perfumed unless you are into organic fulltime. I used perfumed coconut body butter and it done the same thing as the organic because i couldnt afford to pay for more organic products.
I used teaspoon full of emu oil. But if its too oily shampoo your hair with your normal shampoo as an extra rinse to get it out. But still do not use conditioner. The emu oil doesnt necessarly have to be used as i used witout emu oil and it still is good. The emu oil is also to give it abit more lather and shine. My hair doesnt become oily when i use the emu oil even if i dont rinse it.
