Which of the following should a client avoid after a manicure?

After receiving a manicure, a client should avoid using nail polish remover. This is because nail polish remover typically contains harsh solvents that can dry out and damage the nails and surrounding skin. It can also strip away the protective top coat that has just been applied during the manicure process, thereby negating the benefits of the manicure itself.

On the other hand, washing hands is generally encouraged to maintain cleanliness, while applying lotion can help to keep the hands and nails moisturized and healthy. Wearing gloves is not often necessary post-manicure unless the client is engaging in activities that may expose their hands to water or irritants for an extended period, but it does not inherently harm the manicure. Thus, using nail polish remover is the most advisable item for a client to avoid after a manicure to ensure both the longevity and health of their nails.
