What is the use of knot sealer? It is for minimizing shedding and prevents hair loss. You need to utilize this material as a form of preventive maintenance.
Aside from the label, knot sealers usually come in a spray bottle or aerosol spray can. So where do you need to apply it? The knot sealer is sprayed onto the lace on the wig’s underside. It is not made to have any contact with the hair strands.
The only problem with this one is that knot sealer needs to be reapplied each time the wig is washed. To make sure, use it on an as needed basis. As a first time user, you can use the knot sealer to initially strengthen the knots of your invested accessory.
If you will for a knot sealer or clear acrylic sealer in the market, you can visit craft stores such as Michaels or home improvement stores like Home Depot. You can look for products like Patricia Nimocks Clear Acrylic Sealer, Minwax Polyurethane spray and even 3M77 Adhesive.
