The nails of the fingers and toes and the hair of the scalp and body can be affected by local disease and also by internal diseases. This is why a nail problem or a hair problem in and of itself is reason enough to see a dermatologist. Hair and nails are of high priority to us, but the body when in distress often let’s go of hair and nail production. In this way, thin nails and hair loss can tell the dermatologist that the body is under physical and emotional stress. Local disease is common such as fungus and bacterial infections, allergic reactions, and dermatitis related to dandruff. In summary, you should not put off a hair and nail problem because it may seem trivial to you.
