LOL! Nope! I'm all 4b, baby! I actually see a lot of people claiming 4b and 4c and 4z proudly.
To me, natural type 4's have the prettiest hair. I think a 4b natural is doing more than a type 3 natural because people still look at you when you are a type 4 natural as having "nappy" or "bad" hair.
I actually have a friend who is a type 3 and she wears her hair cut short. She's always had issues with thin hair and now it's to the point that you can see her scalp.
But like I said before, if they come out with the right product to make a 4 look like a 3, there will be some 4's who get it and will claim they got "good hair."
