Half Forms Extension Molds

Half forms are partial upper forms used to create nail extensions from the top side of the nail, but they do not fully close over the cuticle-side area like traditional full dual forms. The open proximal edge helps keep the cuticle area more visible and accessible during placement.

This design can help technicians control product placement near the natural nail base, reduce unnecessary pressure at the cuticle area, and focus the form on building the extension body, sidewalls, free edge, and C-curve.

Full dual forms usually cover the nail more completely from the cuticle area to the free edge. Half forms have a more open design on the cuticle-side edge, which makes them a more targeted option for sculpting the extension while keeping the proximal nail area easier to see and control.

• Full dual forms – cover more of the nail surface and help create a full upper-form extension structure.
• Half forms – leave the cuticle-side area more open while shaping the extension body and free edge.
• Open proximal design – helps with visibility, product control, and cleaner placement near the nail base.

This half form collection is built around two targeted form styles. Each option combines a specific shape, length, and C-curve profile.

• Ballerina Short – short ballerina-style half form with Medium C-Curve.
• Square Extra Long – extra-long square half form with High C-Curve.
• Medium C-Curve – softer, more natural side-to-side curve.
• High C-Curve – deeper side-to-side curve for a stronger sculpted profile.

Choose the half form based on the desired final shape, extension length, and C-curve. The form should sit securely on the prepared nail without squeezing the sidewalls or leaving large gaps.

• Ballerina Short / Medium C-Curve – best for shorter ballerina extensions with a softer curve.
• Square Extra Long / High C-Curve – best for longer square extensions with a stronger, deeper curve.

Because the cuticle-side edge is open, the technician can better monitor the product near the proximal nail area during placement.

• Acrygel upper form extensions
• Polygel nail extensions
• Builder gel sculpting
• Short ballerina nail extensions
• Extra-long square nail extensions
• Extension work where cuticle-side visibility matters
• Salon services where shape consistency and speed are important

1. Select Ballerina Short or Square Extra Long based on the desired final shape and length.
2. Choose the C-Curve style that fits the extension goal: Medium C-Curve or High C-Curve.
3. Apply acrygel, polygel, or builder gel inside the half form and spread the product evenly.
4. Place the form onto the prepared nail, keeping the open cuticle-side edge aligned and visible.
5. Press gently to secure the form without flooding the cuticle area.
6. Cure fully according to your product system, remove the form, and refine the extension.

Proper fit matters. If the form does not match the nail width, curve, or desired length, the final extension may require more correction after curing.

• Remove uncured product residue before it hardens inside the form.
• Clean according to your salon protocol and the material compatibility of the form.
• Keep forms dry before storage.
• Store forms by style and curve for faster selection during services.
• Avoid bending, crushing, or exposing forms to direct heat.
