There are basic guiding principles for creating the perfect eyebrow – measurements involving the spacing and the relationship between space, angles of the face, the nose, and the eyes as to where the brows should begin, end and where it should arch. However, there’s a great variance between different faces and how brows suites each - there is no one “perfect brow” for all. It will take some basic measurements to measure out your client's face, look at symmetry (no one is perfectly symmetrical, not even supermodels) and work out the best way to balance your client's face. Engage a conversation to understand what your client are used to, what their personal makeup style is, and your color preferences. Sometimes, some subtle changes are made to shape and color, if you think this could achieve a better result.
