Most of these are pretty recent, not even a year old, so what's going on here?
I personally think they should be aliased to their respective hair color (red_Streaks -> red_hair), OR streaked_hair so that whenever someone wishes to use them, they see how it should be tagged instead.
Nuking or deprecation would probably work well too.
