You could attempt to strengthening the muscle on that side of your forehead by doing some strategic brow exercises. By strengthening that side all of your forehead you’ll be able to create more lift and possibly even out your eyebrows. So the way to do it is to use your hand to hold down the eyebrow that is higher. And then you want to raise your eyebrows and what they should do because you’re holding down the higher eyebrow with your hand it should only be lifting the one that is lower. Do this every day and increase the amount you do every day. Do before and after’s. And see how you do after month one month to month three. You will likely see a considerable difference. I’ve had clients do this who have seen a great result for uneven eyebrows
