The half wigs have a built in headband, which is part of the wig. In my opinion, it looks very good. You can't even tell that it is a wig, since you can not see where the headband ends and the hair begins. On most regular wigs, you can clearly see the scalp.
There is one thing about these wigs that you should know. Inside the wig, there are two of these, one in the front and one in the back:
When Vanessa was wearing this wig before, for several days straight, it left small holes on her head. Those marks are permanent. It also left a line on her forehead, from the headband - but that went away after a few hours or so, after I took off the wig.
You can't see much of the holes in the picture, but when you look directly at her head, you can clearly see them. It doesn't matter much, since she's always wearing a wig that covers those holes anyway, but still. With UV light you can see the holes better.
As you can see, it does not look good. So to avoid having this happen to your doll, if you were to buy a half wig - all you have to do, is to make a small adjustment. Just put some sticky tape over it. I did that on the one in the front only, that was enough. Never had any more problems since then. And remember, this is inside the wig, so you won't be able to see the sticky tape when your doll is wearing the wig.
That's about it. An easy adjustment to avoid small holes in your doll's head. I have many wigs and this one is definitely one of my favorites. Highly recommended. Just remember, if you leave the wig on for a couple of days, you will get that line around her forehead from the headband. Even if it's not permanent, you still may want to avoid it - so just change her wig every other day or so.
