The most common cause of hair loss is genetics, which refers to hereditary patterns of hair loss that can be passed down from one generation to another. This type of hair loss, often referred to as androgenetic alopecia or pattern baldness, affects both men and women and is characterized by a gradual thinning of the hair over time. Understanding that genetics plays a crucial role is important because individuals with a family history of hair loss are more likely to experience it themselves.

Environmental factors, while they can influence hair health and may lead to temporary hair loss, are not considered the primary cause. Similarly, improper hair care practices and dietary deficiencies can contribute to hair loss, but they are generally secondary factors that may exacerbate an underlying genetic predisposition. Knowing that genetics is the leading factor in hair loss allows professionals in the cosmetology field to provide informed advice and support to clients dealing with this issue.
