Are the Knots in Lace Front Wigs Double Knots or Single Knots?

Generally the single simple knot is used around the perimeter or along the front of the wig. The simple knot blends in better and creates a more naturally looking hairline on the wig because they are not as bulky as the double knot.
The double knot is almost always used along the back of the wig, and along the top of the wig. All of the knots on these type of wigs should be sealed with a spray sealer after purchase. If you need help understanding more about this, go online to wig shops and find their customer service information. Then reach out and submit a support ticket to ask any questions.
