What are nail forms primarily used for in nail enhancements?

Nail forms are primarily used to extend nail enhancements beyond the fingertip, which is critical for creating various styles and shapes in artificial nails. The forms serve as a supportive structure that allows the technician to build and sculpt the enhancement material—such as acrylic or gel—beyond the natural length of the nail. This gives clients the option for longer and more elaborate designs that complement their personal style.

The other choices do not accurately reflect the primary function of nail forms. Providing color to the nail typically involves the use of nail polish or gel-color products, which is separate from the structural purpose of forms. Creating a smooth surface for polish application pertains more to finishing techniques rather than the use of forms. Lastly, securing artificial nails permanently is not the role of nail forms; they are temporary supports during the application process, while the actual bonding of enhancements to the natural nail involves other methods and products.
