Why should you avoid metal tools contacting hair during a chemical texture service?

• A. Metal tools can cause color changes on hair.
• B. Metal tools strengthen the curl.
• C. Metal tools have no effect.
• D. Metal can react with chemicals and cause uneven processing or rust staining.

Answer: (C)

Metal tools should be avoided because the chemicals used in texture services can react with metal. This reaction can alter the strength of the processing solution where the metal contacts the hair, leading to uneven processing and patchy curls. Metals can also corrode or rust, leaving stains on the hair or transferring residue, which is hard to remove. Using nonmetallic tools helps keep the chemical action uniform and prevents staining, giving more consistent results.
