I was going to say just that. Some people (not saying the OP necessarily) will do nearly anything not to be considered a category 4. I can see someone wanting a type to just group their hair in without having to use more than one, but really there's very few people whose hair fits into one category. Most people have two if not three different textures on their head. It disheartens me when people try to fit their hair into a category it's not because 4 is still seen by some as the dreaded of hair types. You know how women are all "I'd become natural if my hair wasn't so "nappy""...4 is that "nappy" they don't want to be. Then again I guess I shouldn't care so much because other people's thoughts/opinions of their own hair has nothing to do with mine...
Like I said, I'm not trying to say I feel like you're saying all that OP because you seem sincere in what you're saying and I'm gathering that you don't feel your hair fits into any given types. I'm just saying that I don't think adding another type is necessary. If you feel that 3D should be a type though, go for it! These things aren't concrete. Shoot, be what you wanna be as long as it benefits your hair.
