No, hairpieces are not necessarily one-time use. The lifespan of a hairpiece depends on various factors such as the quality of the materials used, how well it is maintained, and how frequently it is worn. With proper care and maintenance, many hairpieces can be used multiple times over an extended period.
Hairpieces made from human hair generally have a longer lifespan compared to those made from synthetic fibers. Human hair pieces can be washed, styled, and treated similarly to natural hair with proper care.
