Many women worry about hair loss: every time they wash, blow-dry, or comb their hair, it falls out in clumps. Seeing all that hair on the floor is really worrying, making them fear they'll go bald one day. Why is your hair getting thinner? What causes hair loss? Next, let's break it down for you.
1. Brushing hair back or tying it too tightly. If you often wear your hair in a very tight braid or frequently pull it back, constant tension can cause gradual hair loss. This type of hair loss is most noticeable at the hairline.
2. Excessive stress. Hair loss caused by stress is known as psychogenic alopecia. In daily life and work, if you're under significant pressure, mentally tense, or extremely negative, it can easily lead to poor local blood circulation, alter the hair's living environment, and trigger hair loss.
3. Inflammatory stimulation. If hair follicles become inflamed, such as with folliculitis or tinea favosa, it destabilizes the hair roots. The follicles cannot provide sufficient nutrition, causing hair to fall out and become thin. Additionally, inflammation can cause itching, leading people to scratch and pull their hair, which can make it even sparser and may even lead to bald patches.
4. Aging. As people reach middle age, their metabolism slows down, and the body's various functions decline. Insufficient nutrient supply to the scalp slows hair growth, making hair loss progressively more severe.
5. Lack of exercise. Not engaging in sports can slow down the body's metabolism, leading to hair loss. Regular exercise, on the other hand, helps relieve stress and promotes better sleep, which in turn supports the normal metabolism of skin and hair, preventing hair loss.
6. Direct sun exposure. If you experience more hair loss in the summer, it might be due to inadequate sun protection. The thermal radiation in summer is highly irritating to the human scalp. In mild cases, it can cause hair loss, and in severe cases, it can lead to scalp damage and shedding.
7. Nutritional deficiencies. If your hair lacks iron, it can become dry and dull, and may even lead to significant hair loss. Additionally, a diet low in protein or a deficiency of B vitamins in the body can also cause hair loss.
8. Over-styling and dyeing. To stay fashionable, many people frequently visit the salon for perms, dyes, or straightening. However, excessive styling and dyeing can irritate the scalp, easily damaging the hair and follicles, leading to dry, yellow, and brittle hair, as well as hair loss.
9. Improper hair washing. Bad hair care habits can increasingly damage your hair! Behaviors like scratching your scalp with your fingernails, applying shampoo directly to the scalp, applying conditioner to the entire head, or blow-drying immediately after washing can all contribute to hair loss.
10. Medical conditions. Developing conditions like polycystic ovary syndrome, which leads to long-term hormonal imbalances, or thyroid diseases that cause excessive or insufficient thyroid hormone secretion, can disrupt the hair growth cycle and lead to hair loss.
Everyone loses hair, and shedding is a normal process. However, if you notice your hair is getting thinner, you should pay attention to whether you are engaging in any of the above behaviors and take timely preventive measures for your hair's health.
