I saw there could be lots of reasons for premature hair graying, from genetics to actual health problems, but whatever the reason, it may be a good idea to dye your hair if you really get intimidated by this until you heal yourself or use biokinesis to change whatever it is to change. I would personally dye it a few months until I see what the problem is and start to change.
My dad and his brother had half of their hair grey already by the time they were 20, both being very healthy now as well. Is not that much of a big deal, my parents met when my dad was 26, so if you do not feel confident in it, know that love goes beyond a hair color if it comes to genetics.
You can just enter a trance state and ask your own subconscious what is the actual reason for that, wait for the answer, and when you get it act to solve the problem. Do biokinesis if it is that, or satanic healing, and go see a doctor (and considering the current situation make sure that doctor is a very close person, and you do go to the private hospital at least), or search for natural remedies online if you know exactly what you do have after asking your subconscious.
