I had straightened my hair.. it has become very dry and unmanageable. Please help me as regard what to do for my hair. Please tell me how to wash my hair and then what to use to make them silky? Also give me detailed instruction after washing my hair

Before you straighten your hair you need to put hair jell in it and blow dry completely. Then try straighting it. If that doesn't work for you then do an at home conditioning treatment. You can either use your hair conditioner you use now or go get an hair oil treatment. After you shampoo, put your conditioner in and leave it in. When you get out get a plastic sack or a large sandwitch sack they both work. Put it on your head covering your hair and get the blow dryer and completely dry your hair with the conditioner in it or the oil whitch ever you have used. Take the sack off after hair is dry and then wash out the conditioner. Then style as you choose. If it doesn't work for you let me know and I'll think of something else for you that could work.
