The heat perm thermally ______ the hair using the perm solution and heated rods.

• A. Reconditions
• B. Hydrates
• C. Damages
• D. Conditions

Answer: (A)

In a heat perm, heat speeds up the chemical action of the perm solution so the hair’s bonds can break and rearrange into a new shape. The word reconditions fits this idea because it describes renewing the hair’s internal structure into the new configuration under heat. Hydrates would imply adding moisture, which isn’t the main action here; damages would describe a negative effect, not the intended process; and conditions would suggest surface conditioning rather than rebuilding the internal bond structure. So thermally reconditioning the hair best captures what the heat perm does to prepare and set the hair for the new shape.
