What are some good home treatments/remedies for dry over-processed hair?

i heard vitamins A E and fishoil vitamins, looks like you straighen it so yea oils would help with the iron. another suggestion is to take a bic razor to your hair and start over, your hair will seem thicker and healthiey because the ends are tappered but your gonna have to live with a bald head for a couple of weaks. i used to have long hair and also straightend mine with the same problem, then i biced it and now my hair is awsome but sounds like you fear cutting it. **** what people think about you if they judge you for your hair in a cruel way thees people are not friends
