My hair used to be really frizzy and curly (Like a lot of black men have), i went to the barber to get a haircut, and the barber put some kind of thick white paste i my hair, which straightened my hair. He told me it'll go away in a day. Now, more than a month later, my hair still isn't back. It's slowly turning back, but now i just looks really ugly. My question is : What did this guy put into my hair and how do i change it back???
