Oh hell no!
No way!
I am around 20 years older than you and I am not ready to go grey yet. I don't mind looking my age, but like hell am I prepared to look 10 years older! (And I know this debate has been done to death, and there are opposing views/different opinions, but in my opinion, grey hair on a person is ageing...)
On these threads, you always get people saying they know loads of people who went grey in their 30s, and even their 20s, yet I don't know a single person who did, except 2 men - and even they were mid to late 30s. I guess a few may have gone grey and dye it and never tell anyone, but I don't KNOW anyone who started to go grey before middle age. If they did they kept it quiet.
Also, you seem to get lots of people on these this type of thread who 'embraced the grey' at 35 or so, but in real life, I don't know anyone who did that, certainly not any women anyway.
Gonna be hard to keep grey at bay if you have dark hair, but maybe you could have hi-lites/balayage?
