Yes. XMH hair extensions allows for restyling to blend perfectly with your own hair. 4.Can I dye the hair? Yes. We recommend color it by experienced colorist, and test a small piece to see if the result came as you expected before dying the whole hair extensions. Please remember that lightening will damage the hair and shorten the hair life span. So we recommend color it darker rather than lighter. 5.How can I distinguish the human hair from synthetic hair? The easiest way is to do burning test. Human hair burn out quickly and become ashes. Synthetic hair burns become a twisted ball with a plastic smell. 6.What is your return policy?
