What to call the area where the hair directions all change on the head? In Russian that term is макушка, and looking for the translation I find it to be top.
However, that is not a satisfactory answer, since some people have two areas on their head where the hair changes its direction. Also, sometimes these areas are not on the top of their head.

I know this as a crown, and some people are described as having double crowns. Wikipedia however suggests the term hair whorl and also mentions the terms swirls, trichoglyphs, and cowlicks.
