It starts with the finest quality Russian and Indian Remi hair, gently processed without any dye and without damage, in a wide variety of gorgeous colors and lengths. Next, the secret and key to BondPlus Extensions is the hair strands are pre-bonded with tinned copper which support natural hair growth. Then each strand is coated with silicon powder natural rock and affixed with your own hair through eco-friendly tubes that shrink upon heating and hold the extensions in place up to 3 months. Once the tube is heated up again, it opens and leaves the hair free of any residue or the need to use any chemicals, which makes BondPlus the most gentle hair extensions technique on the market. Additionally, BondPlus Hair Extensions can be re-used over and over again, saving you hundreds and hundreds of dollars.
