Will my hair grow back thicker?

No. This is physiologically impossible. There are two types of hair that grow on your body. Vellus hair, which when cut or removed will grow back the same size and shape, therefore, the main structure of vellus hair does not change and is not altered by dermaplanning. Terminal hair however, is physiologically coarse. When this hair type is cut it will always grow back coarse. Dermaplanning is designed to treat the vellus hair which is located on the face. Once vellus hair is cut it will maintain a blunt edge and this blunt edge will not physiologically alter the hair itself.
