Conversation:
Good afternoon.  I have purple hair, yes purple.
Neat, did you apply hair coloring or hair dyeing to it so that the color can be changed?
I used dye, it lasts longer.
Cool, what was the reason for your hair color change? Was it for a fashion reason or something else such as covering white hair?
For fashion reasons. Do you know how much hair color change will cost if I get it done professionally?

Response: Oh, so to change hair color by a hairdresser will be about $200 to $1000 USD.
