Hair that has too many disulfide bonds broken and will not hold a firm curl is considered?

• A. Over processed
• B. Under processed
• C. Normal
• D. Damaged but curlable

Answer: (A)

Disulfide bonds in hair provide the structure that holds a curl. In chemical textures, these bonds are broken and reformed to set a new shape. When too many bonds are broken, the hair’s internal structure becomes weakened and its elasticity drops, so it can’t maintain a firm curl. This is what we call over-processed hair. Under-processed hair hasn’t broken enough bonds to shape the curl, normal is the expected result, and damaged but curlable describes hair that’s damaged yet can still form some curl. So the description matches over-processed hair.
