How come you put relaxer on your hair now you got bumps?

It really depends on how long you keep the relaxer on your head.For example,I left my relaxer on too long on some parts(mainly in the front) and when I went to go wash it,I didn't get those areas very good.My sister said that my hair had burnt and would develop what I call Relaxer Left-On-Too-Long Bumps.I made the mistake of scratching it and when I felt it,the top of my finger was dabbed in red.It will bleed,so avoid scratching it.You'll be fine,just wash your hair and don't scratch again.
