Yes, of course! You'll keep a safe distance from your bonds while using the hair-dryer and any other hot, or heated, tool. You can dry your hair just don't put a super hot hairdryer right up to your bonds, you will lose your extensions. You can style your hair just like you would your natural hair just don't place the hot iron ON the bonds. Your bonds can handle what your skin can but if it will burn your skin, it will burn your bonds, too.
This is what one ManeMaxx customer says: “It's the best thing out there for do it yourselfers! For sure, this is great stuff for the girl next door who wants to look like a celebrity.”
