Yes, you can request to have the knots on a wig or hairpiece fully bleached. Bleaching the knots helps create a more natural-looking appearance by reducing the visibility of dark knots where each strand is tied to the base material.
However, it’s important to note that not all wigs or hairpieces are suitable for full knot bleaching. The ability to bleach knots depends on factors such as the type of wig construction and materials used. Human hair wigs generally offer more flexibility in terms of knot bleaching compared to synthetic wigs.
