Wigs, when worn properly, should not destroy the hairline. The key is in the application and maintenance of the wig. Frontals are popular because they provide a natural-looking hairline, but improper use can cause damage.

To prevent hairline damage:

1. Ensure your wig or frontal fits correctly to avoid excessive tension.
2. Use gentle adhesives and remove them carefully to avoid pulling on natural hair.
3. To maintain the health of your hair and scalp, regularly wash and condition them.
4. Avoid wearing wigs for extended periods without giving your natural hair a break.

By following these practices, you can enjoy the versatility of wigs and frontals without compromising your hairline's health.
