Start with the result you have in mind. A classic manicure is a simple choice when you want tidy shaping and a polished natural look. Gel polish can be a good fit when you prefer a cured colour finish. Structured gel or an extension service may suit a different goal, but the right option depends on your nails and should be discussed with your technician.
Consider your calendar, too. Some services need more time in the studio or a planned maintenance visit. If you have an event coming up, share the date when you book so your technician can help choose an appointment that leaves room for the result you want. Bring a reference photo if you have one, and be open about the length and shape you are comfortable wearing.
You do not need to know every product name before you arrive. Tell the studio what you like, what you want to avoid and how much upkeep feels realistic. Your technician can explain the available services, timing and price before you decide.
