I am very much a feminist in that I believe that women need to make the individual decisions that are best for them, and they need to be free to make those decisions without judgement. While I wish there weren't societal pressure to colour so that those decisions could truly be personal (and not society-driven), I have no judgement for those who colour.
It does sadden me when people say that partial grey (10% or a few strands or what not) is not an "intentional" style. If it is natural and a woman prefers not to colour, it is absolutely intentional, and it is and can be just as stylish as a dramatic streak or greater amounts of grey. In other words, your hair can look great going grey regardless of what your original colour is and regardless of how quickly or slowly it turns. Indeed, sometimes natural greying is preferable to colouring and then going cold-turkey and dealing with obvious grow-out. There isn't a right or wrong way to have natural hair.
And yet despite all this, I am conflicted. I am coming up on 45 and my grey has become noticeable to me at my hair line and scattered along my part. I struggle with whether I want to colour or not. I don't FEEL old enough to have as much grey as I do, but I am not sure I like the idea of colouring because if I start that now, it will be much harder to stop. I have very warm hair, despite it being dark (auburn), and I wonder how grey (naturally cool or ashy) will change how my complexion looks or the colours I can wear well. And to be honest, I somewhat lament lost youth, despite being happier and more confident than I have ever been. But lamenting doesn't make it not so, so is denial (for me, not implying that colouring one's hair equals denial for anyone else) the right approach?
I work with younger children who already think that anyone who is a teacher is ANCIENT. To them, 24 and 44 are the same difference, and both are old. So I am not sure how much it matters in that respect. There are teachers with varying amounts of grey or artificial colour, so I don't expect much judgement either way. It is an internal struggle for me that I have been battling for almost a year.
