Most oils make my hair dry. So far, I can only use them as a pre-poo or in my deep conditioner. After my leave-in, if I apply oil, I'm left with dry, crunchy hair. It's very annoying because I can't 'lock' the moisture in, so my hair is dry by the end of the day.

Maybe I should try locking with some type of butter? But I've had bad experiences with butters sitting on my hair and leaving it greasy.

Low porosity hair is a pain in the bum.
