I wish I could go purple all over, but it would be "frowned upon" at work. I'm going to be the coolest retiree one day though - purple hair, diamond nose piercing & beautiful tattoos. I just hope I don't get too wrinkly before then. lol. My mum looks great at 65 (she looks at least 10 years younger), so hopefully I have good genes.
When I was in my late teens/ early 20s I experimented with different colours - red, black, blonde/ blue highlights. It was fun. I agree with an earlier poster who said you're teaching your kids to be individuals.
Personally I think dark hair would look better on you, as I'm sure it would bring out your beautiful eyes, but you're only young once & we all need variety in our lives. It looks really well done & pink is pretty.
