If the hair can dyeing, heating plate clip?

Welcome to Bythairshop
You can do anything to your human hair extensions that you would do to your natural hair!
So yes you can dye or perm your hair, however we recommend you to seek help from a professional hair stylist to avoid any disasters.
Because they are fragile like natural hair, we would not want you to damage them beyond repair.

Our recommendation is to dye deep color, such as #2 #4 #1, and avoid bleaching or heating plate treatment, which will damage the hair.
