To be or not to be - gray

The new growth actually looks more white than grey to me.

Actually, gray hair is not actually gray. It's white hairs mixed with darker hairs that just looks gray from a distance. I read this and surely found it to be true on my own head. And depending on the color(s) of the dark hairs, and the proportion of white to darker, gray hair has many "shades". Up close each hair is a different color. So you are mostly white, not really "gray".

The true salt-and-pepper steel gray look that many think of as "gray" hair is actually very dark brown or almost black hair mixed with white hairs. Because my own hair has blondes and various shades of brown plus white, it has a blonder gray look to it rather than that bluer steel gray. One of my co-workers is true steel gray, and I'd be willing to be that she had very dark hair when she was in her 20s, though I didn't know her then.

Have you considered a temporary or semi-permanent color as your hair grows out, if you don't like the "line"? That would give you a more consistent look until your hair is long enough to get all the permanently colored part cut off and just let the temporary color wash out.
