Immediately. You can see it in this picture of poor Mila Kunis.
It’s really just a matter of taking away their eyebrows. Let this be a lesson to all of us – never shave off your eyebrows. Even if you’re going to draw them back on. One rainy day the eyebrow pencil you’ve drawn them on with will smudge away and you will be left looking like some kind of crazy monster. Though possibly this is not a major concern for anyone since it’s not 1985. Was that the last time people routinely shaved off their eyebrows and drew them back on? It was either 1985, or 1925. Either way, do not do it. And if you want more ways to make beautiful people look absolutely awful, please check this out (we especially like the idea of giving them Steve Buscemi eyes). - Buzzfeed
