All of these treatments can be done together. However, there are a few things to remember:-
1. Always do chemical treatments prior to waxing as the pores will be open and waxing can remove the very surface layer of the skin leaving it sensitive to chemicals.
2. Make sure you use a perm safe tint and a tint safe perm for your treatment so that you do not over chemically process the hair.
3 Most importantly, ensure you carry out your skin testing in accordance with manufacturers instructions.
