Tape-in extensions are the most cost effective or bang for buck of all the extension methods. The extensions can reused multiple times and with proper care and maintenance can last up 6-12 months. The extensions themselves are made of 100% human hair and can be treated and styled just like your own hair. They attached to the hair by using a medical grade adhesive that is easily removed from both your hair and the weft by using a specially formulated remover. With this method, you can add length, volume, even out a hair that is growing in, or add dimension or pops of color.
