Which of the following is NOT a purpose of artificial nails?

Artificial nails serve several purposes in the realm of cosmetology, predominantly focusing on aesthetic enhancements and the improvement of nail strength. One primary function is to add length to natural nails, allowing for a variety of styles that may not be achievable with natural nails alone. Additionally, artificial nails enhance the overall appearance of the hands, providing a polished and fashionable look that many clients desire. They are also known for their durability, as they can withstand wear better than natural nails, which might be prone to breaking or chipping.

Treating fungal infections, however, is not a purpose of artificial nails. In fact, applying artificial nails over a fungal infection can exacerbate the problem, as the artificial covering can trap moisture and bacteria, leading to further complications and growth of the fungus. Therefore, while artificial nails offer beauty and resilience, their application does not extend to therapeutic purposes, particularly in the context of health and infection treatment.
