As all of our hair extensions are 100% human hair, for the most part, additional processing in terms of colouring has been successfully achieved by many of our clients without issue.

We would advise performing this on a test strand first to ensure you are able to achieve the finished look you desire, before going ahead and processing the entire set.
We have some articles on our website that go into further detail about this that we think you may find useful -
