Bring Your Nail Inspiration. Let’s Plan the Details.
You might love the color in one photo and the shape in another. Tell us which part of each image you want to use.
ColorThese details make your request easier to understand:
Shape: Round, oval, square, squoval, almond or another preference.
Length: Your natural length or the amount of extension you want.
Color: Sheer, milky, opaque or a particular shade.
Finish: Glossy, matte, chrome, glitter or cat eye.
Art: An accent nail, repeated details or a different design on each nail.
Budget: Your preferred total before any optional additions.
Lighting and filters can change how a color looks on screen. Compare a physical swatch when an exact shade matters. For complex art, discuss feasibility and appointment time before confirming the booking.
Your First Visit, from Choosing a Service to the Final Check
Tell Us What You Want to Keep or Change
Mention your preferred length and anything you disliked about a previous set. “Keep my nails short” or “I want a softer square shape” gives your artist useful direction.
Bring Up Existing Product and Timing
Tell us about removal, repairs and a firm departure time when arranging the appointment. A design request can require more time than a single color service.
Check the Shape and Color
Ask to review the shape and chosen shade before the design progresses. If something looks different from what you requested, explain the change you want.
Speak Up About Comfort
Tell your technician immediately if something feels uncomfortable. You do not need specialist nail vocabulary to ask a question or request a pause.
Frequently Asked Questions
Your total depends on the service, nail length, design and any removal needed. Check our price menu for the base service and applicable extras. For custom art, share your inspiration photo, preferred length and budget when requesting a quote.
Start with whether you want color, added length or maintenance for an existing set. A manicure keeps your natural length. Extensions add length, while a fill maintains a suitable existing enhancement. Mention any product already on your nails so removal gets included in your request.
Book ahead when you want a particular artist, detailed nail art or a specific time. Contact Nail Theory to check walk in availability before traveling. A simple color appointment and a detailed painted set require different amounts of time.
Allow time for the complete service, including removal and nail art. A single color manicure involves fewer steps than extensions with detailed designs. Tell us about existing product and your design when booking, and request the appointment duration before making your next commitment.
Bring your photo so we can assess the design and plan the details. Point out the shape, color and artwork you want to keep. For example, milky white polish with chrome looks different from opaque white with glitter. Your nail length also affects how much detail fits.
Yes, nail art does not require long extensions. Fine French tips, small flowers, accent details and simple patterns can suit short nails. Choose a reference with a similar length so you can judge the design’s proportions.
Gel polish adds color; gel extensions add length. If you like your natural length and want a gel finish, look at gel manicure options. If your reference shows longer nails than you currently have, discuss an extension service.
Ask us to confirm removal for your existing product before booking. Tell us whether you have acrylic, dip powder, gel polish or another enhancement. Different systems need different removal methods, and removal time and charges should be included in your appointment plan.
Wear time depends on the nail system, application, nail condition and daily use. Frequent hand washing, cleaning and repeated pressure on the tips affect wear. Ask for care instructions and a maintenance interval for your chosen service rather than using another person’s results as a guarantee.
Speak up during the appointment about the shape, and contact us promptly about a repair afterward. Describe the change clearly, such as “shorter” or “more rounded.” For a later chip, lift or break, send your appointment date and a clear photo. Our service policy explains repair conditions and any charges.
