i love oils, i use em all the time, every day, for n with everything, same of my faves are: coconut, argan, hemp, tea tree, peppermint, lavender and also cocoa and shea butter. they can be used for sealing, for scalp messages, to help with styling, to add shine, detangle..... anything you can think of. its just about finding what works for you. i really enjoy mixing my oils together, starting off with a base, coconut oil or almond oil, and adding same argan, hemp or emu oil, (where the really good stuff is, vitamins n that) and adding lavender or peppermints for smell.
same types of oil are too heavy if you have thin hair, mines rather thick and heavy so i can be rather heavy handed, but you really have to start off with a bit and just add more until your happy with the amount you've applied.
cause the "good" oils can be rather pricey, argan, emu and hemp, i always use the base oil when im mixing, you dont have too, but its the best for me, cause i still get the good stuff but it helps stretch it.
you'll be able to get them online, at discount shops and health food shops. when buying them look for "cold pressed" "virgin" or "unrefined" dont even bother looking at anything else. I would also make suret hat the oils are pure when you buy them cause with the expensive oils they can add somthing else to it.
i hope you enjoy using oils as much as any other oil junkie does
