please help us!!
Go to Sally's beauty supply & buy those little moister conditioning packet. Put it in your hair and leave it for a few hours & rise with cold water. Do this 1-2 times a week.Don't use heat on your hair for awhile, no dye. I don't recommend you using shampoo either. Don't wash your hair very much, don't use hot water in your hair.
Definitely do deep conditioners regularly now, no heat at all on your hair; blow drying, straightening, no more chemicals like bleach, dye, perms. I would also get hot oil treatments done, at home or at a salon.
I would go to a hair salon and ask for professional help.
