Some researchers believe that human hair loss is caused by imbalanced nutrition. When the human body cannot absorb balanced nutrition, the hair follicles will shrink and cause hair loss. However, some opponents believe that hair loss is caused by damaged hair follicles. When After the hair follicle is damaged, it is in a "false death" state, and the hair follicles degenerate and shrink, causing the hair to stop growing and gradually wither and fall off. Which of the following, if true, would most weaken the opponent's point of view? ['hair follicle damage is caused by imbalanced nutrition.', 'long-term undernourished people often have yellow hair and are prone to hair loss.', 'using shampoo can also cause some damage to the hair follicles.', 'Damaged hair follicle prevents it from absorbing nutrients from the scalp, which leads to hair loss.']
