Thanks everyone for posting, all the words of encouragement to keep asking for it are much appreciated!
How I see it could work is that they could add to cartel market some kind of complexion bundle with would have 3-5 most used options but recoloured (ginger, whitish, a few shades of blonde). This way they could have our money and we could get what we are asking for. It seems like such a low hanging fruit.
Also keep in mind that there are people in Star Wars universe with white hair and white eyebrows such as Atris and Handmaiden.
