Yes, but there are many different Native hairstyles besides just “having long hair”. Hairstyles varied from tribe to tribe. And in most tribes individual Indigenous people wore their hair differently from one another. Just like today, not every “white person” has a “Justin Beiber bob.” So every Native has their own individuality.
Different American Indian people chose different hairstyles based on what was popular in their clan or village. Often times, hairstyles were used to identify which tribe someone was from. Native Americans in some Plains and Western tribes continue to place great spiritual value on their hair, cutting it only when they are in mourning.
