What type of brush is typically used during a gel nail application?

During a gel nail application, a synthetic fiber brush is typically used. This is because synthetic brushes are designed to handle the viscosity of gel products effectively. They provide a smooth application and allow for precise control, which is critical when working with the often thicker gel formulations.

Synthetic fibers are durable and resistant to the chemicals found in gel products, making them suitable for repeated use without degrading over time. They also tend to hold their shape better than natural fibers, which can be advantageous in ensuring consistent application techniques.

In contrast, nylon bristle brushes might not offer the same level of control or precision required for gel applications, as they are commonly used for different types of applications in nail care. Natural fiber brushes may absorb the gel product, leading to waste and uneven application, while foam brushes lack the necessary firmness and precision required for detailed work in gel application. Thus, the use of a synthetic fiber brush is the preferred and most effective choice for achieving a flawless gel manicure.
