that is conjecture X''D justbecause it /could/ doesn't mean it /is/ and the numbers don't really pan out. look at avatar sites, at artoons, at non-realistic art in general and you will see a trend(over many decades, geographical locations and cultures) that reduces facial distinction and emphasizes unique(within the context of the current space) outlines. the shorthand for that recognition in human-shaped characters is generally art as we have very strong social attachments to hair in almost every culture and it is the one pert of the body that gives the most allowances for personal representation. it is socially encouraged that we mark ourselves by what our hair does and does not say about us as individuals and so is often provided as a means of making that distinction in artistic media. in fact it is one of the selling points of avatar websites that there are lots of types of hair for the users even when there is not much of anything else and hair is a widely-chosen item for recolours and set-breaking(it is also used in adoptables and cartoons to make distinctions between same-face/body characters)
