U tip is also called Nail tip, a kind of popular keratin hair extension that is attached to natural hair when the keratin is melted with a heat connector. Keratin extension is designed for easy and long-term attachment. The u-tip attachments are very thin, comfortable, and invisible blended with your own hair.
Use quality Italian keratin, which keratin structure resembles closely to the structure of human hair, and the protein will not damage the hair when it is attached to its hair. The tips are made manually and neatly, which is stronger enough to avoid the hair being pulled out or broken.
Recommended being applied by a certified hairstylist. It maybe takes a few hours to install. A specific solvent allows you to remove the keratin extensions easily.
