What additional tool is needed for gel enhancement besides basic supplies?

The use of a synthetic brush for gel enhancement is essential because it is specifically designed to apply and sculpt gel products effectively. Gel enhancements require precise application and manipulation to achieve the desired shape and finish. A synthetic brush allows for smooth application and helps in spreading the gel evenly across the nail surface, ensuring that it adheres properly and cures well under a UV or LED lamp.

Different tools serve various purposes in nail care; for instance, a metal file is typically used for shaping and smoothing nails, while a buffer polishes the nail surface. A stick applicator is commonly for applying products that may not require a brush. However, these tools do not provide the same level of control and finesse needed when working with gel products, making the synthetic brush the critical additional tool in this scenario.
