If you want to cover a balding scalp, a men's hairpiece is a good method of doing so. The primary goal of any hairpiece is to look as unnoticeable as possible. You want the hairpiece you sport to look as much like your natural hair as possible. You certainly don't want anyone to know you are wearing a mens hair piece.
A good mens hairpiece can be made of either real human hair or synthetic hair. Real hair has a tendency to look the most natural since it is in fact natural hair. Synthetic hair can also be quite natural-looking and it holds curl and style better than natural hair. If you have naturally curly hair, a synthetic hairpiece is a good option.
When you are looking for a men's hairpiece, you'll want to match it perfectly to your existing hair. The color should be an exact match. A close match isn't good enough as only a perfect match will keep people from guessing about your hairpiece.
You'll also want to match the texture of your real hair. If you have incredibly fine hair, coarse hair will not work for your hairpiece. If you purchase a quality hairpiece, the hair will be inserted into the piece at angles to replicate how real hair falls. You can get a very good result if you take the time to do your research and shop around for the right piece.
