Cause of gray hair and actual ageing

  1. Jul 25, 2014 #1
    I have learned that a catalase increase may help feed peroxide and reduce gray hair but on the other hand human ageing states that its heme-Fe increases automatically overtime. These two "facts" really confuses me. Could you help me explain this ? Thank you.

    As we age their is less of the chemical that keeps the hair dark!

    We need to find out this chemical!

    Melanocytes is the short answer. The produce the pigments that color hair. When they die out you get grey hair. It is not necessarily age related.
