Make sure to choose oils that, even when diluted with water, will not stain the crown, and be sure to disperse the oil well, so that, while scented, it won’t be bad for your hair (or, again, the crown). One thing I’ve never really mentioned is that it can be difficult to evenly disperse essential oils in water, given that they are, of course, oils, but it’s not impossible, so give it a go, but do your research and keep dangers such as allergies in mind for safety’s sake.
