Hair straightening requires the use of chemicals to break down the bonds of the hair and then manipulate it in a straightened form. Of the given options, only B refers to this chemical process used for the creation of straightened hair. A, C, and D are incorrect because they describe different processes that do not involve the use of chemicals. Permanent straightening is a process of curling hair permanently, not straightening, using heat or dampness. Heat straightening or flat ironing utilizes heat to temporarily straighten hair. Keratin treatment, also known as a Brazilian blowout, uses a protein treatment to relax and de-frizz hair. In both of these options, the hair is not permanently straightened using chemicals.
