response: So a hairdresser can do it but it can also be done at home.
original_response: I am a hairdresser that does hair coloring.
history: Hello, do you really have purple hair? No, do you practice changing hair colors, which is the practice of hair dyeing? Neither, I don't even know who to go for it!
knowledge: Hair coloring can be done professionally by a hairdresser or independently at home.
