Using harsh chemicals should be avoided to maintain healthy hair structure because these substances can adversely affect the hair's integrity. Harsh chemicals, commonly found in certain hair dyes, relaxers, and styling products, can strip the hair of its natural oils and proteins, leading to damage, breakage, and loss of luster. Over time, this can make the hair more susceptible to environmental stressors and may even result in scalp irritation.

In contrast, regular trims, deep conditioning treatments, and moisturizing products contribute positively to hair health. Regular trims help remove split ends and prevent further damage, while deep conditioning treatments provide essential hydration and repair to the hair shaft. Moisturizing products are vital in maintaining the moisture balance of the hair, preventing dryness and brittleness. Together, these practices support the overall health and appearance of hair, making it vital to avoid anything that could undermine these beneficial habits.
