The care of toenails and fingernails is often discarded as a minor aspect of personal care, even though having healthy and clean nails is hygienic and can prevent the onset of infections. Older individuals and those with disabilities or conditions can often find taking care of toenails particularly difficult. Toenails and fingernails protect the tips of toes and fingers from damage. They are made of a protein called Keratin and can provide an indication of general health.
