The human hair weft
is sewn or wefted to a track that becomes a human hair wig. The wig which is
constructed to cover and add volume to the entire header part of the hair is
known as the human bulk There are the number of hair strands which are fixed on
the top of the head at the place where we want to give a little volume. Once
the bulk hair is attached to the head, the entire natural hair looks filled
with volume strands covering the empty area and can be modulated the way we
want it to be like straight, curled, wavy etc.
