You can always just shave off all or part of your eyebrows and draw them back in or apply false ones. I know two women who do this because they are dissatisfied with the appearance of their eyebrows. I never noticed either woman did until they mentioned it in conversation. One shaves them all off and draws them anew, the other shaves about half and fills the rest in.

You have a LOT of non permanent options for altering the appearance of your eyebrows. If you wanted to go permanent or semi permanent, there's also eyebrow tattoos.. the technique I've heard of is called microblading and it lasts for a few years.
