Our I-Tipextensions utilize a high quality keratin tip specially designed for hair extensions and refined after thousands of experiments. The thickness of the tip is strictly regulated to be around 0.7 cm, and is always smaller than the smallest micro-ring. The two major tools for application of our I-tip extensions are micro-rings and shrinkies. Our Microrings are lined with rubber on the inside, which prevents damaging your own hair. Shrinkies are plastic rings that shrink when heat is applied (simply blow hot air on them with a hairdryer).
