Essential oils are volatile and liquid aroma compounds from natural sources, usually plants. Essential oils are not oils in a strict sense, but often share with oils a poor solubility in water. Essential oils often have an odor and are therefore used in food flavoring and perfumery. Essential oils are usually prepared by fragrance extraction techniques such as distillation (including steam distillation), cold pressing, or extraction (maceration). Essential oils are distinguished from aroma oils (essential oils and aroma compounds in an oily solvent), infusions in a vegetable oil, absolutes, and concretes. Typically, essential oils are highly complex mixtures of often hundreds of individual aroma compounds.

My mom walked by me one day and had this look on her face like she was about to throw up. Then she walked closer and said "What is that ransid smell...That's your hair smelling like that!" I was sooooo embarased and of course my sister had to run up and take a whif as well to add her 2 cents in. I cowashed that evening and have never baggied again. I'm just so upset because I cannot do twist outs or braid out without s-curl or profective because I will get breakage and I am tired of my hair being crunchy and dry. I am also tired of being self-consious about the smell of my hair. Why can't I have my cake and eat it too? Can't I have long, soft, and pleasent smelling hair? 
They think it's funny to tease and don't mean to be hurtful. I am really the only one who takes their comments to heart, but my mom was not teasing, my hair was starting to smell like mildew from baggying. I thought I was getting a whif of bad smell, but I didn't think anything of it because I thought the coconut oil would overpower it. But I guess sometimes you just can't smell yourself.
oke:......I'm reformed now
