Can a mixed girl get sister locs?

Hi, I f17 want sister locs however I am mixed race (half Nigerian half Caucasian) and I’ve never seen anyone who is biracial with sister locs. I’ve always thought they were beautiful and have wanted them for years but I don’t want to sink 800 dollars into something that might not work for my hair texture. I have 3a/3b leaning more towards 3a hair.

I’m not in touch with my father’s side of the family so I have no people in my personal life to ask about this. I’d appreciate help I don’t get much help with my hair as is because I was raised by my white mom and step dad who is also white.
