While all of our extensions are made with 100% Remy Indian hair, we recommend avoiding chemical alterations as our colored hair has already been previously treated. If you decide to custom color your Perfect Locks extensions, we highly recommend taking them to a licensed professional for this service. Any lightening/bleaching of extensions should be avoided altogether. Also please keep in mind, lightening can alter the wavy and curly texture. Generally, color depositing is safe but results may vary. In this case, we would recommend ordering a lighter color to achieve your desired hair color.Friendly Reminder this alteration does void our return policy.
