Which type of gel should be used for a client with flat nails to create an arch?

The choice of builder gel for a client with flat nails to create an arch is based on the gel's specific formulation and intended use. Builder gel is designed to provide strength and support, making it ideal for enhancing the shape and contour of the nail. Its thicker consistency allows for the creation of a more pronounced apex, which is essential in achieving the desired arch.

This type of gel can be sculpted and molded to form a high point on the nail, which not only creates a more aesthetically pleasing appearance but also improves the durability of the nail enhancement. The builder gel adheres well to the natural nail and can be used to reinforce the structure, providing both lift and longevity.

Other types of gel, such as top coat gels and base gels, do not possess the necessary properties to sculpt and build the arch effectively. Top coat gels are typically used for finishing purposes, providing shine and protection, while base gels serve primarily as a foundation layer for other products. Thin gels, being less viscous, lack the strength and structural support needed to successfully create an arch on flat nails. Thus, builder gel is the most appropriate choice for this application.
