Nope, split ends mean dead hair, no way to revive the dead bit or rub it back together with hair products.
Cut the split ends off and then get it trimmed regularly if you grow it back. Also keep your diet healthy, what you eat is what goes into your hair and it needs nutrients like vitamins, proteins and natural fats not sugars and transfats.

There is a technique of trimming split ends without losing any hair length. What you do is you twist your hair and with a good pair of scissors you cut off any bits of hair that sticks out or you wrap your hair around your finger and do the same.
To maintain being free from split ends, you will have to nourish your hair as much as possible and avoid heat styling for good.
