Some hairstyles that are smoother or longer tend to lay flatter, showing the partings.
That's why the need for a scalp that looks natural.
Those scalps, while beautiful, are usually on a slab of rubber though and can add to the discomfort of wearing a full wig.
If your style if fuller and doesn't show a parting, you can wear a more open weave wig. Not only are they cooler but you can use a crochet hook to pull your natural hair through the openings to achieve a highlighted look or just to make it more secure feeling.
All these variations in cap styles and hairstyles really just add to the fun and the choices.
I hope that helped.:}
