Today I noticed my four year old son had a grey hair (he has had one before). He is very dark and this grey hair is virtually white and a bit frizzy. Is there anything to worry about (some sort of dietary deficiency) or is it just one of those things? Thanks.
One of my college friends was substantially grey at the age of 18. A year or so later he had completely silver hair, with almost every girl in the college seeking to date him because of his 'distinguished' look!
