The first step to trimming eyebrows is to brush hair up using a comb. The hair that is up above the shape can be removed. You can use haircutting scissors, or if you prefer, eyebrow scissors (compare prices) which are much smaller.
Sometimes this step is all you may need if your brows aren't that long. But if you have a lot of bulk, then you'll need to a little more work which we'll show you in the next steps.
