Um i guess it is possible.But you don't want to put grease and oil on your hair like that.it's gross and hard to wash out.plus it could clog up your shower drain.I think using less heat and stuff on your hair could make it grow faster and longer.vitamins as well.get alot of proteins and nutrients.
i would not think so. Mineral oil is chemacly made and im guessing would coat ur hair like it just coats ur skin,.
olive oil (extra virgin) will help repair and nourish ur hair and prevent splitends thus leting ur hair grow longer.
