How often this happens depends on the sturdiness of the base, whether human or synthetic hair is used (synthetic hairs are typically more durable and less resistant to fading).
Also semi-permanent hair pieces may need to be replaced more frequently simply because they are worn 24 hours a day and subject to wear and tear during sleep and showering. Of course, you can sleep and shower with your hair piece on if you use other methods of attachment, you also have the option of removing the hair piece during these times.
