I  have red hair and fair skin and never had sore nipples.  This was also 17
and
 14 years ago when I was given terrible advise.  I do not believe skin
 sensitivety is related to your hair or skin colors.  There are many factors
 that can not be easily and quickly catorgorized.

I agree completely with Ann that fair skin or red hair does NOT mean a mother
is more prone to sore nipples.  I think that is a convenient  excuse for the
person giving the advice and makes them lazy mentally, stopping them from
seacrching for the true cause or working to help the mother.  I have worked
with plenty of red heads and their problems and causes of sore nipples are
just the same as anyone elses.
