10 Reasons Why Women Lose Hair

Thyroid disease. Too much or too little thyroxine secreted by the thyroid gland can disrupt the hair growth cycle. Hair loss is often not the only symptom of thyroid disease; it is often accompanied by weight gain or loss, sensitivity to cold or heat, and changes in heart rate.

Polycystic ovary syndrome. Women with this disease have long-term sex hormone imbalance and excessive male hormones, which manifests as excessive facial and body hair and sparse hair. It can also lead to ovulation problems, acne, and weight gain, among other things. Sometimes, thinning hair is the only symptom of the disease.

Alopecia areata. The body's immune system mistakenly attacks healthy hair follicle cells, causing hair loss in patches. In most cases, the hair will grow back within six months to a year.

Ringworm. The condition is caused by a fungus and has a typical pattern of hair loss - itchy scalp, red, rounded areas of hair loss, and a scaly scalp. The disease is contagious, so the patient's family members should also be tested.

Fertility. Some women experience thicker hair during pregnancy, thanks to changes in sex hormone levels, which can cause hair to survive longer. But after giving birth, when sex hormone levels return to normal, the hair will fall out quickly. In some cases, it may take two years to recover.

drug. A lesser-known side effect of birth control pills is hair loss. Medications that suppress ovulation can cause hair thinning in some women, especially those with a family history of hair loss. In addition, anticoagulants, drugs for high blood pressure, heart disease, rheumatism and depression may also cause hair loss.

lose weight. If you lose weight quickly through dieting, you are more likely to lose hair. Once your diet returns to a healthy level, your hair will start to grow back. A diet low in protein or high in vitamin A can also lead to hair loss.

Anti-cancer treatment. Both radiotherapy and chemotherapy can cause hair loss. After treatment is stopped, the hair will grow back.

Extreme pressure. Severe illness or major surgery, heavy blood loss, extreme negative emotions, etc. can cause a person to lose half or even all of their hair, which may last for 6 to 8 months.

Hair tied too tight. Many women find that they experience hair loss if they wear cornrows or tight ponytails or headbands that are too tight. These improper hairdressing habits can also easily leave scars on the scalp and lead to permanent hair loss.
