Final answer:
The mother’s specific reason for not wanting her son to dye his hair is not provided in the text, but common reasons could include concerns about chemicals, appearance, or social implications.
Step-by-step explanation:
The mother’s reason for not wanting her son to dye his hair is not explicitly stated in the given excerpts. However, common reasons a parent may object to hair dyeing can be due to concerns about the chemicals involved, the permanence of the change, the desire to maintain a natural appearance, or perhaps a belief that such a change is unnecessary or inappropriate at the son's age. In some cases, parental objections may also stem from concerns about the child’s motivation for wanting to dye their hair and what it might signify about their self-image or peer influences.
Without more specific context provided in the question, it is not possible to determine the precise rationale behind the mother's viewpoint. It is important to remember that each family might have its own set of values or cultural norms influencing such decisions.
