To grey or not to grey?

Is today's question.

It was really tricky taking a photo of my hair (& I haven't really managed it but I got bored trying) but I wanted to take this shot as it has been on my mind today.

I've been going grey since my twenties & I wish I could stop dyeing it, but am I ready to let go of my life as a brunette 30-something & accept who I really am?
