Compare and contrast the way hair and nails protect your body?

Hair and nails both serve protective functions for the body, but they do so in different ways. Hair acts as a barrier against environmental elements, helping to regulate temperature and protect the skin from UV radiation and minor abrasions. Nails, on the other hand, protect the sensitive tips of fingers and toes, preventing injury and enhancing grip. While both are composed of keratin, their structures and protective roles are adapted to their specific locations and functions on the body.
