How much polish should be on the brush for one layer?

The ideal amount of polish on the brush for applying one layer is a bead of polish at the end of the brush. This provides a controlled amount of product, allowing for an even application across the nail surface without pooling or running. A bead allows the technician to spread the polish smoothly and evenly, which is essential for achieving a professional-looking manicure.

Using a dripping brush could result in excess polish, leading to uneven application, smudges, or bubbles as the polish may run or take longer to dry. Conversely, a fully saturated brush might also lead to the same issues, overwhelming the nail and making it difficult to maintain precision. Not using any polish would naturally mean no application can take place, which would not meet the requirements for a manicure. The controlled bead of polish strikes the right balance for effective application.
