Then you trigger them that the women that slept with the Nazis in WW2 were shaved just like that....by locals to humiliate/punish them after liberation.
Its not even ironic...
Anyways make it easier to know which ones to avoid..... always some bright weird hair colour or they going baldie, nothing normal in between.
Though I am being a bit unfair, I do know some girls that have bright pink/blue hair that are very nice decent people...but they tend to be rare among the group.
