Excessive hair loss from your lace wig can be a problem if you do not care for it properly. There are some maintenance techniques that will help prevent hair loss. First seal the knots on your unit before using it and after each wash. A very good knot sealer product to use is called Knot Sealer. Turn the wig inside out, spray on the mesh or lace, and let it dry completely before putting it on.
Once you wash your unit, let it air dry. After the cap is completely dry, apply your sealer. It is also effective to spray extra hold hairspray on tights or lace. Some wig wearers use an acrylic sealer. It can be purchased at your local craft store.
Another thing that can cause the wig to shed excessively is applying oils or conditioners near the base of the wig where the knots are. This can cause the knots to loosen and slip when brushing or styling the hair. Even if you use a knot-sealing product, the use of oils and conditioners can weaken its effectiveness.
When applying conditioner to your unit, try to avoid knots in the base. Make sure your hair is completely dry before combing or brushing it. If the hair is not completely dry, the hairstyle loosens the knots. Although it may not fall out right away, once the hair is dry and you start styling it, your wig may start to shed. Also, avoid excessive brushing and combing of the wig. Remember that the longevity of your wig depends on how well you take care of it.
