The phenomenon of hair loss starting from the crown is usually associated with multiple factors. Genetic factors play a key role in the development of baldness. Research indicates that genetic traits are highly dependent on androgens; when androgen secretion is active, it may lead to increased sebum production, which can block hair follicles and subsequently cause hair loss, often beginning at the top of the head. Seborrheic alopecia (androgenetic alopecia) is also a significant factor. This type of hair loss typically presents with an oily scalp, increased dandruff, and gradually thinner hair with reduced density, usually starting from the vertex. Nutritional status, mental condition, and lifestyle habits may also influence hair growth, but these factors generally do not specifically lead to hair loss starting from the center. Baldness beginning at the crown is primarily due to genetic and seborrheic alopecia influences, with genetic factors playing a decisive role.
