Why does it happen?

1. Play of Hormones: Hormonal imbalance is seen in women during menopause, perimenopause, pregnancy, and in endocrine disorders, such as polycystic ovarian syndrome (PCOS). Progesterone and estrogen are two important female hormones. Progesterone keeps a check on estrogen levels. When progesterone levels are too low, it leads to a state of hyperestrogenism which triggers excessive hair shedding and hair loss. Dihydrotestosterone (DHT) is a potent form of testosterone that normally leads to hair loss. Women, who produce high levels of male hormones (androgens), have increased testosterone levels which can convert to DHT, leading to hair loss.

2. Stress: When a woman experiences any stressful condition, her adrenal glands increase the release of cortisol (stress hormone). This leads to secretion of adrenaline which leads to increased levels of testosterone and DHT.

3. Under or over performing thyroid: An overactive thyroid and lack of sufficient parathyroid hormone can also result in thinning of hair. Accompanying symptoms are fatigue, unexplained weight gain, aching joints, constipation, dry skin, feeling cold all the time, and poor sleep.

4. Pregnancy and childbirth: Pregnancy and childbirth change a woman’s hormonal balance and can result in hair loss. Therefore, it is normal for postpartum mothers to experience thinning of the hair and even bald patches. Such hair loss is temporary and heals itself within several months.

5. Menopause: Menopause also leads to hair loss. During menopause, a woman’s estrogen levels fall and are no longer in balance with DHT levels. This low estrogen level and high DHT lead to hair loss.

6. Nutrient deficiencies: Low levels of certain nutrients within the body, for example, vitamins A, E, and iron may result in hair loss.
