Tape-in hair extensions are a semi-permanent hair extension method. They consist of thin strips or wefts of hair with a specialized adhesive tape attached to the top. These extensions are applied by sandwiching a small section of your natural hair between two tape-in wefts, creating a secure and discreet attachment. Tape-in extensions are designed to add length, volume, and sometimes color to your hair, and they typically look very natural when applied correctly.
