What are Knots?
Knots are the tie that holds the hair to the lace. A simple knot is used mainly around the perimeter or the front of the lace hair. This allows the lace hair system to blends more easily into the hairline. Double knots are a bit thicker and can be used along the perimeter, top and back of the system. The lace hair system after care is vital as the knots should be sealed after washing to extend the life of the system and prevent excessive shedding.
