is it possible that the chemicals in perms and hair relaxing products misfigure or cause dents in ones scalp? and what cause dents in scalp besides direct head trauma externally?

I don’t believe that relaxing products and perms will cause physical deformities like dents in your scalp. They are known to cause hair loss and burns when associated to allergies or misuse.
