What is the name of the process that rearranges extremely curly hair into a straighter form?

• A. Chemical relaxer
• B. Thermal reformation
• C. Permanent curling
• D. Hair smoothing treatment

Answer: (A)

Rearranging extremely curly hair into a straighter form is achieved with a chemical relaxer. It uses alkaline chemicals to break the disulfide bonds in the hair’s cortex and then re-form them in a straight configuration, producing a long-lasting straight result until new growth appears. A neutralizer is then used to set the new bond structure. In contrast, thermal reformation relies on heat to temporarily reshape hair, permanent curling creates curl rather than straightening, and a hair smoothing treatment smooths or coats the hair without permanently changing the bond structure.
