A topper is sometimes referred to as a “half wig” or “top piece”, but usually, people will just call it a topper. Basically, a topper only covers the top portion of your head. Toppers vary in size, depending on the coverage you need – there are toppers that are only 2 by 4 inches and just sit on top of your part, and there are toppers that are 8 x 9 inches and almost cover up your whole head! The topper attaches to your hair with clips, and your own hair is worn down underneath to supplement the hair on the topper.
