Title:FILL IN THE BLANKS Description Evaluate each scenario. Decide whether the action of the person was rational/safe or irrational/dangerous. TYPE S for Safe and Rational U for Unsafe or Irrational Hair dyes contain hydrogen peroxide to remove coloring of hair. H202 when combined with any metal produces an exothermic reaction. With this in mind, it is important to look first at the ingredients of your previous applied chemicals on the hair before deciding and applying a new one.
