So, hair lenght is the ultimate measurement of magic power (as far as we know), but does volume have any impact on it too? For example, Veda's hair is not that long compared to other witches, but dang, does it have a presence. Or what about an afro? :o

yeah, curly hair’s length is measured as if it were pulled taut (straight), which does add a bit of length. in the case of veda, she has fairly loose curls and i can’t imagine it would be more than a couple of inches longer. idra is a good example, because she has dreadlocks, so her hair would be a lot longer than it seems.
