While you may have a brow expert on staff at your spa, it never hurts to get some advice from a pro. As such, I wanted to pass along this handy chart from Malynda Vigliotti, owner of Boom Boom Brow Bar in New York City, who shapes more than 500 brows a month. She says she regularly fields questions from her clients on achieving the perfect brows. First, she advises clients to let their brows grow out, then she suggest clients follow the following six steps. How does your spa's brow-shaping strategy compare?
