There are several reasons that having a backup hairpiece is a necessity!
You can extend the life of the hairpiece by up to six months by alternating. This also alternates the placement of the clips, which prevents further hair loss.
If something unexpected happens you have another hairpiece ready to go.
By preparing your hair ahead of time you extend the life of the hair by letting it air dry instead of blow-drying.
When you buy 2 hairpieces together you can ensure a more perfect match.
