There are many people with so-called 3a, b, c, xyz, etc hair who wish that they had nappier(4a or b) hair. Not everyone promotes the 3abc is best type of attitude. I personally HAVE 4a hair that is VERY compact and just plain NAPPY, and I adore it. I don't sit and wish for other types of hair. I only wish for the knowledge to properly maintain the type of hair that I have.
On topic, you will find MANY people who feel that "God" or inspiration, or the universe, or whatever they believe in has given them a message to give to the "poor" women whose hair won't grow long. They feel like our saviour, as if having short hair is a curse. Then when you approach them with something contrary to what they are SELLING, they get touchy.
I originally came here to get inspired with the knowledge to grow my hair long. Now I realize that hair grows well enough on its own, and products don't really SAVE hair, but techniques DO. I wouldn't waste time debating over hair typing and what someone that I really don't know anything about is growing out of their scalp. We REALLY don't know celebrities true hair types, because they lie so much in Hollywood anyway.
