If the 1:20 test solution boils within minutes, gives off an unpleasant odor, and the hair degrades and pulls apart easily, what element is indicated?

• A. Hair contains copper, do not perm
• B. Hair contains silver, do not proceed
• C. Contains lead, do not proceed
• D. No metallic salts, proceed

Answer: (A)

The test is identifying the presence of metallic salts in the hair that can react with the perm solution. When copper is present, the 1:20 test solution tends to boil quickly, gives off a strong, unpleasant odor, and the hair weakens and can be pulled apart. This happens because copper ions actively interfere with the hair’s disulfide bonds and with the chemistry of the perm solution, causing heat, gas release, and structural breakdown of the hair. Because of that destructive reaction, you should not proceed with the perm if copper is indicated.
