TAPE-IN HAIR EXTENSIONS
This method uses adhesive weft tape that doesn't require any heat, but also lets your hair grow easily. It does require you to get a silk press before installing.
Lasts up to 4-6 months with proper care. They are reusable for up to two years and are good for 3-4 applications. Once you remove the tape extensions you clean them, add new tape, and then reapply them.
Takes 7-9 days to customize.
