What is the baby hair for a wig?

For a lace human hair wig with baby hair, Dorawigs trims a few of the wig hairs at the hairline in order to make the wig look more like a natural head of hair. If you wanna do a ponytail and not show the cap, it’s better to choose a wig with baby hair or at least with back only baby hair.（https://www.nerissahair.com）https://www.nerissahair.com
