2. Hormonal Imbalances

Hormones play a major role in regulating hair growth. Conditions like thyroid disorders, polycystic ovary syndrome (PCOS), or menopause can disrupt this balance. For example, an underactive or overactive thyroid can cause hair to become thin, dry, and prone to falling out. Hormonal shifts after pregnancy or stopping birth control can also trigger temporary hair loss.

3. Stress and Emotional Strain

Physical or emotional stress can push hair follicles into a resting phase, a condition known as telogen effluvium. This often happens after major life events such as illness, surgery, or emotional trauma. Hair may start falling out in clumps a few months after the stressful event. The good news is that this type of hair loss is usually temporary once the body recovers.
