That's what I did yesterday evening - and it was just lovely! I had olivoil in my hair - it should be in for about 1 hour, and the hair shall be wrapped in a towel. Use schampoo directly in the hair after that, don't wet it. Might need to use schampoo two times, to get rid of all the oil. No conditioner shall be used afterwards.

I ate tasty and healty snacks [grapes, carrot and rice bisquits], sat comfortably in bed and read the latest issue of Elle and then I had a long, hot and wonderful bath-time with divine scents and cosy candles :3 Damn I felt good afterwards!
