Final answer:
Super strength ammonium thioglycolate relaxer is designed for use on coarse, resistant hair because its strong formulation is necessary to break the robust disulfide bonds found in thicker hair textures.
The Correct Option is; A) Coarse, resistant hair.
Step-by-step explanation:
Super strength ammonium thioglycolate relaxer is used for the chemical straightening or relaxing of hair. During this process, disulfide bonds in hair proteins are selectively broken by the reducing action of the thioglycolate.
Ammonium thioglycolate is a potent reducing agent, designed to manage and restructure very curly or resilient hair textures.
Given its strength and powerful chemical composition, super strength ammonium thioglycolate relaxer is ideally suited for use on coarse, resistant hair (A) rather than fine, delicate hair (B), natural, unprocessed hair (C), or chemically damaged hair (D).
The reason for this is that coarse, resistant hair has more robust and abundant disulfide cross-links, which require a stronger formulation to relax or straighten properly. Fine, delicate, natural, or chemically damaged hair might be overly processed and harmed by such a strong relaxer.
