When do females start losing their hair and how does it happen?

Age: The most common cause of hair loss in women is androgenetic alopecia, also known as female pattern baldness. This condition is caused by a combination of genetics and hormones, and it typically begins after menopause. However, it can start as early as the 20s or 30s. Androgenetic alopecia is characterized by a gradual thinning of hair on the scalp, beginning at the temples and crown. The hairline may also recede.

Hormones: Estrogen and progesterone, two hormones that are produced in large amounts during pregnancy, help to keep hair in the growth phase. After menopause, levels of these hormones decline, which can lead to hair loss.

Other medical conditions: Certain medical conditions, such as thyroid problems, anemia, and lupus, can also cause hair loss. If you are experiencing sudden or unexplained hair loss, it is important to see a doctor to rule out any underlying medical conditions.

Medications: Some medications, such as chemotherapy, can cause hair loss as a side effect. Hair loss from chemotherapy is usually temporary and will grow back after treatment is completed.

Stress: Stress can cause hair to fall out temporarily. This type of hair loss is called telogen effluvium. Telogen effluvium can occur after a major life stress, such as a divorce, job loss, or the death of a loved one.

Trauma: Physical trauma to the scalp, such as a burn or a scalp injury, can also cause hair loss.

Hairstyles: Certain hairstyles, such as tight ponytails or braids, can put tension on the hair and cause it to break. This type of hair loss is called traction alopecia. Traction alopecia can be prevented by avoiding hairstyles that put tension on the hair.
