Anyone else seeing this small visual bug on their practical ponytails haircut?

This is a really tiny thing but I was messing around with hairstyles for my highlander WoL and I noticed this little visual bug in the front of the hairstyle. Under most light sources it's barely visible and I hadn't noticed it until now despite having used the hairstyle for months but it's one of those situations where now that I know it's there I can't not look at it. Easily ignored but the weird thing is I don't think my viera had the same thing? I was just wondering if anyone else had seen this on any of their characters or is it just highlanders?
