When it comes to hair extensions, there are endless options to choose from. But if you're looking for a sleek and seamless look, then you'll want to choose either u-tip or i-tip hair extensions. Both types of extensions are made from high quality human hair and can be styled just like your natural hair. The main difference between the two is how they are attached. U-tip extensions come with a nail-like tip that is heated and then wrapped around a strand of your natural hair. I-tip extensions, on the other hand, are attached with a small stick that is inserted into a bead, or glued directly to the hair with keratin glue. The bead is then clamped shut, securing the extension in place. With either option, you'll end up with beautiful, long lasting extensions that will transform your look.
