When a wig is plucked, it is less dense in front, which is exactly the case with real hair. If you inspect your strands, you will notice hair of unequal length and some short baby hair around your hairline. This is because new hair grows constantly, and they shall not all be the same length. For a wig to be completely realistic, it must imitate just that. Plucking of the hairpiece creates those perfect baby hairs and a flawless hairline. Pre-plucked wigs are simply superior in appearance to all others.
