Typically, new moms will see an increase in hair fall and hair thinning after giving birth. Estrogen levels fall and their body has a higher level of testosterone and, in turn, DHT, which attaches to hair receptors, stimulating hair to enter the resting and falling stage as opposed to the growth phase.

As you transition into the menopausal stage, you will experience menopause symptoms, such as hot flashes, night sweats, vaginal dryness and itching. To add to that list, the effects will create additional changes on other parts of your body and may cause thinning hair and hair loss.

When you are stressed, your adrenal gland becomes active leading to the production of cortisol, a stress hormone, which increases the production of testosterone and, in turn, converts to DHT, which interrupts the hair’s growth cycle. Stress also constricts blood supply through the capillaries restricting oxygen, nutrients and vitamins from reaching the hair follicles.

Thyroid hormones regulate your body's growth and development processes; thus, hyperthyroidism and hypothyroidism can affect your hair follicles' growth and development. As a result, your old hair strands fall out and are not replaced by new ones, thereby making your hair less voluminous.
