I’d guess 4A because your coils look more S or O shaped instead of zigzags like 4B is supposed to have. They look too big to be 4C to me as well.
What were you guessing?
I was guessing 4b or 4c. I could not figure out if I was seeing “z” or “s”. The ends were coiled . Before this method, I thought 4z and did not think definition was even possible with my hair.
