Would you suggest anything to make the hairs grow longer?

Can you recommend anything to make my hair grow longer? Actually, my hair was long when I was a kid, but later I suffered from typhoid which made me lose most of my hair. Now the remaining hair on my head is very brittle and prone to breakage. I have had a hair-cut in order to let the new hair grow, but it seems to me that its not working. Moreover, I am tired of multiple split ends along each hair strand, that is terrible. Would anyone suggest any home remedies?
