Make sure to thoroughly clean your hair, face and body immediately after your bukkake session. The cleaner you start beforehand, the dirtier you'll look afterward. If you start the session with your hair in perfect condition, you'll really appreciate a good glob of goo on the scalp after the session.

As the session comes to an end, don't be in a hurry to clean all the ejaculate off. Take time to revel in the experience. Once you start the cleanup, make sure to take a thorough bath or shower to completely remove all the ejaculate. You don't want to find a crusty lump in your hair the next day. And ejaculate can imbibe a particular odor upon it's recipient after long enough.
