So let’s talk about why grease is not good for your hair. If you like light, soft, fluffy hair that moves and blows in the wind, then using hair grease is not a good idea. If you have a dermatitis, dandruff or dry scalp, STOP USING GREASE! Grease has petroleum in it which is heavy on the hair shaft and clogs your pours. Grease causes your hair to stick together, making it appear thinner then it is and causing debris to cling to your hair. Grease is not the remedy for dry hair or scalp. Deep conditioners, leave-in conditioners, oils, moisturizers, drinking lots of water and eating a healthy diet are all helpful when combatting dry hair or scalp.
