I don't shed any more than the norm in the winter months and it gets cold and dry here. I use a mouthwash paper cup size and put enough castor oil in it to oil my scalp,then I heat it in the microwave for a second or two, oil my scalp, massage it and seal my ends right after the massage, put my hair up in pineapple style, put in twist, place night cap on and go to bed.

You might want to wet your hair early in the eve so you won't go to bed with a wet head. If your hair is wet when you do this, it shouldn't be greasy when it dries although you should have a healthy shine after you take the twist down and style.
