Long neglected dandruff can cause hair follicles to become blocked due to the buildup of oils and dead skin cells, leading to inflammation and irritation. This can damage the hair follicles and eventually lead to hair loss or baldness. Options A, B, and D are incorrect because they are all skin conditions caused by different factors and not directly related to dandruff. Tinea is a fungal infection, scabies is caused by a mite infestation, and psoriasis is an autoimmune disorder. While dandruff can contribute to the development of these conditions, it is not the main cause. So, the correct answer is C baldness.
