What is a common cause of hair loss?

Poor nutrition is a common cause of hair loss because the body requires various nutrients to maintain healthy hair growth. Hair follicles rely on vitamins, minerals, and proteins, such as biotin, zinc, iron, and essential fatty acids. When a person's diet lacks these essential nutrients, it can lead to weakened hair, increased shedding, and ultimately, hair loss. Proper nutrition supports not only hair health but overall bodily functions, and deficiencies can have significant effects on the hair growth cycle.

Excessive moisture might affect hair texture but it is not a direct cause of hair loss. Regular hair trimming is a practice meant to maintain healthy hair by removing split ends and does not contribute to hair loss. While overusing styling products can lead to buildup or damage, it is generally more associated with temporary hair issues rather than systematic hair loss linked to nutritional deficiencies.
