If there is no reaction after 30 minutes in a 1:20 test, what does this indicate?

Explanation:
Metal salts in hair can interfere with chemical processing and cause unpredictable results or damage. The 1:20 test is used to check for these metals before a perm. If there is no change after about 30 minutes, that result is interpreted as indicating the presence of metallic salts in the hair (specifically silver in this context), so the service should not proceed. Metallic salts can react with the waving solution, leading to poor curl, discoloration, or breakage, so stopping the process is the safe and correct action.
