I overprocessed my hair by dying it. I was wondering if my hair will grow back it's not falling from the root is their anything incan do to help it?

Hair will regrow. Since the hair is not living, there is nothing you can do other than be very gentle with it to lessen to breakage after so much damage has been done with chemicals. Since you did not damage the roots, it will regrow. Lessen learned and consider having a professional dye your hair in the future!
