I see a lot of signature where people write their hair type. I'm familiar with Andre's hair typing. But where are you getting the other hair classifications? I see a lot of M Cii...things like that.
I can't remember where I saw the article with F, M, C and i, ii, iii descriptions.
F = fine strands, M = medium strands, C = course strands
i = few strands, ii = average strands, iii = a lot of strands
