Final answer:
Cosmetologists should have a thorough understanding of nail disorders and diseases to identify unhealthy conditions and provide proper care, but they cannot diagnose or treat medical conditions requiring healthcare provider's attention.
Step-by-step explanation:
Cosmetologists should have a thorough understanding of nail disorders and diseases because they need to identify any unhealthy conditions on clients' nails and determine if they can be treated in the salon. By recognizing nail disorders and diseases, cosmetologists can provide appropriate care and potentially prevent further damage or infection. However, cosmetologists are not licensed to diagnose, treat, prescribe, or work on unhealthy skin or nails. They should instead advise clients to seek the help of a healthcare provider for medical conditions that require professional attention.
