Knowledge: Cars last about 15 years before buying it again while hair dye requires retouch every 4 weeks.

I have only dyed my hair once. nothing permanent a rinse really. WOuld you dye your hair
I don't have hair because I'm a bot. People usually dye their hair to cover gray, for fashion, or to recover their original color after its been damaged.
I love seeing silvery white hair. My kids laugh at me because I have two strands and I brush my hair to make sure they show. LOL.
People can dye their har at home or go to a professional. Which did you choose?
I just did it at home.
Ah, OK. Hair coloring is also called hair dyeing, which is what we call changing the hair color.
Yes, that's true. Do you know how long it will last to do hair dyeing again?

Response: Hmmm yeah, I heard hair dye retouch is required every 4 weeks.
