Which is the longest lasting hair color without any side effects? I'm 21 year

Question

Sonam dubey · Answer

I am being blunt here, no hair colour is safe on hair. But if it comes to staying power, loreal proffessional ammonia free hair colour is good. If you do not have much of grey hairs then please dont use it as you are just 21 years old.
