Installing tape-in hair extensions can be a challenging and complex process that requires a high level of skill and experience. If you are not a trained professional, you may struggle to properly match the color of the extensions to your natural hair, leading to a look that is unnatural and obvious. Additionally, if the extensions are not installed correctly, they can cause damage to your natural hair or even fall out, leaving you with a patchy and uneven appearance. It is generally best to leave the installation of tape-in hair extensions to the professionals, who have the knowledge and expertise to ensure that your new hair looks natural and is applied safely.
