What effect does too thick application of nail enamel have?

Applying nail enamel too thickly can indeed lead to peeling, which is a common issue when the product does not adhere properly due to excess layers. When nail polish is applied in thick coats, it takes longer to dry completely, and the weight of the thick layers can create stress on the polish as it dries. This can result in a poor bond between the nail and the polish, leading to the polish lifting at the edges or peeling off in larger sections.

In contrast to the other effects mentioned, thick application does not enhance shine, promote longer wear, or provide strength to the nail. While a thicker coat may seem like it could enhance the shine or durability, it often does the opposite by increasing the chance of failure in the polish's adherence to the nail surface. Therefore, using a properly balanced application of nail enamel is essential for achieving a beautiful, long-lasting manicure without peeling.
