Bring the makeup you actually use, including the item you suspect is the wrong shade. Clean skin is more useful than a face you have already finished. If you want to practice a specific event — a work headshot, a dinner, a wedding you are in but not the bride — say which one. The lesson can aim at that lighting.
Write down the steps before you leave, or ask the instructor to. Memory is a weak system for “the brush you used third.” A phone photo of each stage, in the same window, is better than a single finished portrait.
Lessons are one person by default. If you want a friend taught in the same hour, say so when you request the time. The quote covers the length of the lesson and whether a second person is included. Private lessons are priced by the hour.
Parents booking for a teenager should say so. The form does not collect a date of birth. Instruction for a school event should stay age-appropriate and practical: skin, a simple eye, a lip that survives dinner. It is not a photoshoot and not a place for adult styling copied from a nightclub.
When you are ready, describe what you want to be able to do without help. Include whether you want a single lesson or a short series.
