Split ends!!!!!!!!!!!!!?

Hi I have REALLY bad hair, I mean like split ends with split ends, its bad! Can split ends be repaired, and I also have the really dry hair underneath that feels all dry and like straw, but the hair on top is normal. So how can I reverse the damage and keep it healthy. Also i'm a vegetarian so are there any cruelty free products that don't have steric acid, gelatin, or glycerin. thanks so much! :)
