We cut hair
Most of our day is clipper and scissor work. We set a length, blend it into the sides, and work out with you how much weight should stay on top so the shape still holds two weeks from now. When you want a fade, we take that blend far enough that you can't find a step in it.
Bring a reference if you have one. A photograph settles more in ten seconds than a paragraph of description does, and we'd far rather see it before the clippers start than after.
