Skin Wefts are hand made with hand knotted hair on a very thin mono-mesh base which has a polyurethane coating. They are called skin wefts because they are invisible without seams and lay flat to match your scalp.
Just use any hair glue or hair tape on the inner surface of the strip and put them on to your own hair. They can be easily removed with any hair glue remover with acetone base. They look natural without any noticeable bumps. These are easy, fast and safe method to add hair extensions.
