There is a woman in my barre class who dyes her hair all-over chestnut, and her full-on gray roots were showing the other day, and I was SO wanting to encourage her to just grow it in! She has a great haircut and her hair is luxurious and thick, and she has beautiful eyes. I know that when she decides to do it, it will look fabulous. Of course, I didn't say anything. But I really believe it will look amazing on her.
I have wimpy hair and the wimpiest of straggly grays. It will probably take me forever to go gray -- it's happening in there, with my highlights but at a rate of a few strands a year.
I love your hair, and I think your gray is looking pretty amazing. I completely agree with everyone to keep going and give it a try as long as you can. You may absolutely love it -- I expect you will be stunning with the full head. But then again, if you decide to dye it all again, I will be behind you too. It's all about choice.
BTW, I think an UWP SHOULD have all gray hair, in an edgy cut. Somehow it fits perfectly with the vibe.
PS Is it gray or grey?
