Hi Aram,
I think that the style that you are doing this with is fine for the hair as well. If you look at the image, at least the size that you posted, it looks just fine. I don't know what it looks like up close so I can't give you any pointers that I might have to share. Perhaps post a 'study' of the image by zooming in on the hair and taking a screenshot of it so we can see it better THEN I/we may be able to advise you better on this area!
