Actually, the hairstyle itself is pretty similar to the original, its just the newer artist draws it more curvy. The original artist's style has sharper edges for hair ends in his work. Thus, it gives the illusion that the hairstyle is more different, because that and the combination of hair colour makes it look different. Aside from the longer pigtails, there is virtually no difference except how the hair is laying down basically. A few strands are also not the same.

Essentially, its similar to how Nana V3 and V4 are different... V3's Nana has more bubbly looking hair, while the newer one looks ore cardboard-er (to me).
