Hi Guys
when you do a re attachment do you use knot sealer every time or is just once sufficient?

Knot sealer is used by some hair wearers to apply a hard clear coating to the knots on the bottom of the unit. Knot sealer hardens like a clear nail polish. One application should last for several weeks. Some people like knot sealer and others claim they really don’t see any benefit to it.
