What is not beneficial when applying toenail polish?

Applying only one coat of color when painting toenails is generally not beneficial for achieving the desired look and durability of the polish. A single layer may not provide enough opacity and can result in streaks or uneven color distribution, causing the final appearance to be less vibrant and polished.

In contrast, applying a base coat is crucial as it helps to protect the natural nail from staining and can improve the adherence of colored polish. Two coats of color enhance the depth of the color and provide better coverage, while a top coat serves to seal the polish, increase shine, and extend the longevity of the manicure. By using more than one coat of color, you ensure a more uniform and professional appearance, which is particularly important for toenails that are often less visible but still subject to wear.
