Why Do I Lose So Much Hair When Washing It?

Hair loss in humans should be taken seriously. Hair loss can affect one's appearance and cause mental stress. What's more, hair loss may indicate underlying health issues, thus requiring prompt attention. If hair loss occurs, it is important to promptly visit a hospital for examination and diagnosis to determine the underlying cause and treat it accordingly. When selecting shampoo, it is advisable to avoid products with irritating ingredients. What are the reasons for excessive hair loss during hair washing? Let's take a look.

There are several reasons for hair loss during hair washing, including nutritional deficiency, chronic diseases, and seasonal influences, which can be both physiological and pathological. It is normal for a certain amount of hair to fall out daily, typically ranging from 40 to 80 strands, as part of the natural metabolic process. During autumn, due to the dry weather and reduced sebaceous gland secretion, hair may fall out more easily during washing. However, as long as the number does not exceed 100 strands, it is still considered normal.

There are several factors that can contribute to hair loss:

• Seasonal hair loss is common in summer due to high temperatures and dilated pores, while hair loss is less common in autumn and winter when temperatures drop and pores close.
• Chemical hair loss can be caused by chemical factors that alter hair color or even cause hair loss.
• Physical hair loss can be caused by factors such as mechanical stimulation and exposure to radioactive substances.
• Nutritional hair loss occurs when malnutrition and abnormal metabolism affect the quality and color of hair, leading to diffuse hair loss in severe cases.
• Infectious hair loss can be caused by various pathogens, including bacteria, viruses, fungi, spirochetes, and parasites.
• Congenital hair loss refers to complete or partial absence of hair due to developmental defects. This can manifest as thin or sparse hair or hair that falls out shortly after birth and does not regrow.
• Endocrine hair loss occurs when hormonal imbalances affect hair growth, such as postpartum or menopausal hair loss.

To manage hair loss, it is recommended to avoid spicy and acidic foods and instead consume milk, beans, black sesame seeds, mushrooms, spinach, celery, black fungus, and other nourishing foods.
