Hair Extension

There are four types of hair extensions, according to Rauchet: tape-in, clip-in, bonded, and halo hair extensions. And while they all share one common goal—creating long, luxurious hairstyles—they're all different in terms of application, texture, and longevity.

Just like your natural hair, extensions need regular washing. “Wash clip-ins every six to eight times that you wear them, depending on how much product you're using,” Thornton says. “Give them a little bath in your sink and dry them on a towel.” Before washing clip-ins, remove them and comb out any tangles.
