Bugged Hairstyle?

Not sure if it's a bug, or what to call it, but I noticed this hairstyle has a graphical error with it where certain parts of the hair wont get any highlights. All other hair styles are fine, it's just this one for some reason. The bug is very noticeable while playing in Ifrit due to all the lighting effects. The hair style is the 2nd option on Hyur

Edit: A more clearer picture of what I mean, on most hair styles the highlights fade out, but here there is a part where it just simply cuts off the colour
