It's pointless to argue over something so opinionated as a inconsistent hair chart. The chart has it's flaws, which is why there is always someone asking for validation. Everyone answering isn't completely sure either if you can tell, they're just smart guesses. Opinions, it's all it is, there is no reason to argue over it. 3D or not, it was the original poster's opinion, only that. Everyone IS entitled to an opinion, and no one should adhere in violating that. It's a hair thread on a Hair-health website, how can you fight over hair?
