Double knots, single knots, half knots, and bleached knots are available. * Double knots are much durable, but it is a little bit visible than other knots. * Bleached knot is bleaching which takes out most of the color leaving a virtually invisible hair knot. Bleached knot provides a more natural looking, but it will weaken the hair knot which reduce its lifespan. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
