Trichologist Explains Difference Between Stress Shedding And Hormonal Hair Loss Patterns

Hair fall has become an increasingly common concern among young adults and working professionals, with dermatologists noting a steady rise in patients reporting excessive shedding and visible thinning. Experts say that while daily hair loss is a normal biological process, persistent or sudden increases in shedding may indicate underlying health or lifestyle issues that require proper medical evaluation.

According to Dr Nandini Dadu, an aesthetic physician and trichologist at Dadu Medical Centre in New Delhi, hair loss is often mistakenly assumed to be caused solely by stress. She explains that stress-related hair fall, medically known as telogen effluvium, usually occurs after significant physical or emotional triggers such as illness, surgery, emotional trauma, sleep disturbances, or major lifestyle changes. In such cases, hair follicles enter a resting phase prematurely, leading to sudden and diffuse shedding across the scalp.

Dr Dadu notes that stress-induced hair fall typically appears two to three months after the triggering event, making it difficult for individuals to connect the cause with the symptom. The condition is often temporary and reversible, with hair growth usually returning once the underlying stress factor is resolved and overall health improves. She adds that patients commonly notice increased hair fall during washing, combing, or even on pillows, but without any specific pattern of bald patches.

In contrast, hormonal hair loss develops gradually and follows a more defined pattern. It is commonly associated with conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, pregnancy-related changes, menopause, genetic predisposition, or general hormonal imbalance. In men, this often presents as receding hairlines or thinning at the crown, while women may notice widening of the hair parting and reduced overall hair density.

The expert stresses that early signs of hormonal hair loss are often ignored because of its slow progression. Unlike stress-related shedding, this type of hair loss tends to worsen over time if left untreated. She advises against self-diagnosis, warning that many people either assume all hair fall is stress-related or rely on unverified home remedies, which can delay proper treatment and worsen the condition.

Dr Dadu further highlights that accurate diagnosis requires a clinical evaluation, including scalp examination, medical history review, and blood tests to check for deficiencies or hormonal imbalances. She emphasises that early intervention plays a key role in managing both types of hair loss, as stress-related cases often respond to lifestyle changes, while hormonal hair loss may require long-term medical treatment to slow progression and support regrowth.
