How do you dye your hair?

Do you wait till baby is sleeping and do it from the box?
Do you go to a salon?
Do you get someone else to watch the baby?

Are you pregnant and secretly still dying your hair (no judgement, I did twice, in 2nd and 3rd trimesters)?

Do you dye it when you're in a bad mood? Or a good mood? Or during a life change? Or when your roots are showing? Or for halloween?

(Can you tell I want to dye my hair again?)
