This is Katie.
She styled my family’s hair when we lived in Wisconsin, and she surprised my husband the first time she took scissors to his eyebrows. His initial shock became delight when he saw the results. Before we moved, Katie taught me how she did it.
Simply backcomb one eyebrow (from temple to nose) and trim with hair-cutting shears whatever hairs come past the spine of your comb.
Katie told me she once trimmed a family member’s eyebrows while camping and there was no comb, so she used a fork. (I always think of Ariel’s “dinglehopper.”) So resourceful!
Katie will always do this more capably than I do, but now every time I cut his hair, I trim my husband’s eyebrows too. Thanks for teaching me how, Katie!!!
