Hi again Roxanna --
Now I may chicken out partway through but I'm here to support!
[Wouldn't you know after seeing so many gorgeous greys (pewter, silvers, whites) on YLF and the internets, seemed like every woman I saw IRL last week was a non-inspiration.]
I definitely agree with comments re hair and skin color shifting together. And whatever color you end up with will no doubt look great with YOUR skintone.
Your "enhanced" shade looks great to me as-is, not gonna lie. So you can always go back. Aside from the money, time, and practically immediate regrowth issue I feel my color is just a bit too dark for me right now. We've [hairdresser and I] have tried to go a little lighter but with such a dark natural base and hair that pulls red it's been difficult. I'm sure if I were working with a top colorist ($$$) I could get there -- every 2 weeks!! -- but I'm already spending more than I'd like.
I will say it seems to take some work to keep grey looking its best, but that's where we wavies/curlies who low- or no-poo etc and understand the hair's hydration need have an advantage. Your curls look gorgeous and healthy now, so I'm sure a few tweaks, if any, will keep them that way as your color changes!
