One of the most innovative types of pre-bonded hair extensions are micro loops, which involve a simple loop and pull technique. Sublime Hair has two methods to applying the European pre-tipped hair: Nail 'U' tip and Stick 'I' tip. Nail and Stick tip hair extensions are dipped in high quality Keratin glue, which can be easily removed without causing damage to your own hair. Virgin European Wavy Nail-tip extensions are applied to the natural hair using a heat connector (hot fusion), whereas Stick-tip extensions are applied using micro rings/shrink tubes and micro link pliers (cold fusion).
