If a client has thin, weak nails, what should the manicurist apply before the base coat?

In the case of a client with thin, weak nails, applying a nail strengthener before the base coat is the best choice. Nail strengtheners are specially formulated products that help to fortify and protect the natural nail, making them less prone to breaking and chipping. They typically contain ingredients that nourish the nail, such as proteins, vitamins, and strengthening agents, which work to enhance the nail's durability.

Using a nail strengthener before applying a base coat ensures that the natural nail is reinforced, providing a better foundation for the subsequent layers of polish. This protects the nails from potential damage that may arise from the application of colored polish or other manicure products.

Other options, such as applying nail polish or a base coat remover, do not address the weakness of the nails. Cuticle remover is primarily used for preparing the cuticle area and does not contribute to strengthening the nail structure itself. Thus, utilizing a nail strengthener is the most beneficial step in this scenario.
