"   Question My son is only three and has a scattering of grey hairs. I am concerned that there is something wrong with him or is he lacking in some vitamin? He is far too young for this. I keep pulling them out.   Answer This is certainly a puzzling symptom that you describe. The only disease that I am aware would cause greying of hair at such a young age is the illness called kwashiorkor, which is due to a deficiency of protein in the diet.  It is most commonly recorded in African countries where the protein content of the diet of poorer people is often very low and it is children who are most affected because their need for protein is relatively high due to their growth.  Besides wasting of the muscles, skin problems, mouth ulcers, lack of appetite, diarrhoea and anaemia, the affected child gets markedly underweight.  The hair changes of kwashiorkor, which is loss of pigmentation associated with the hair becoming fine, sparse and straight, is usually noted in scalp hair.  From the information you have sent me, there is nothing to indicate that your son&amp;#039;s diet is particularly at risk of a protein deficiency so I am unable to say specifically what the cause of his hair changes are.  I do not know of any other specific reasons for the problem you describe, so it may well be worth going and having a chat with your own GP about this one.  Be sure not to remove the evidence beforehand.
