When properly applied and maintained, Tape-in Extensions are safe and won’t damage natural hair. However, improper application, frequent removal, or harsh styling can cause damage. Tape-in Extensions are suitable for most hair types, but people with very fine or fragile hair may need to be cautious. If you have fine hair, it’s important to ensure the extensions are applied properly and not too heavy, as overly thick extensions can stress the natural hair. Working with an experienced stylist and using lighter extensions can help prevent damage and achieve a natural look.
