Hormonal changes are by far one of the most common causes of hair loss. The primary culprit in this scenario is the hormone dihydrotestosterone, often abbreviated as DHT. This hormone binds to the receptors in the follicles causing the hair follicles to shrink, weaken and fall off.

Genetic alterations

Alterations in genes can increase your predisposition to hair loss. For instance, it is the alteration in genes that make hormones such as DHT to cause weakening and shrinking of hair follicles.

Autoimmune diseases

Sometimes your immune system can start attacking your own body. Alopecia areata is a classic example of hair loss that occurs when the immune system attacks the hair follicles.


One of the significant side effects of most strong drugs is hair loss. Medications such as drugs used in chemotherapy, anti-hypertensives, beta blockers, blood thinners, and contraceptive pills can often lead to hair loss

Stress and illness

Stress is also a major contributing factor to hair loss. Additionally, illnesses such as fungal infections - especially those caused by ringworms can cause hair loss.
