Ethnic Hair HELP?

My hair is curly or nappy naturally. Anyhow My sister relaxed my hair 4-5 weeks ago. I've only straightened twice. My hair is falling out. The back is going bald. I keep pecking at it. It's really itchy %26amp; full of dandruff. I've only washed it once. My hair is an afro. What tips, comments, advice to have to help my hair. What kind of shampoo should i use? How many times should i wash my hair? Can I olive oil treatment my hair? It's extraordinarily dry. THANKS SO MUCH

Stop using harsh chemicals! Your hair is very damaged, go to a pro and seek their advise, my guess is, you will need to start over. Get a very short hair cut, and good luck.
