Does stress affect hair loss?

Yes, stress can be associated with hair loss. Studies have established a relationship between stress and hair loss, particularly with three main types of stress-related hair loss:

1. Telogen Effluvium: This condition involves an abnormal shift of hair follicles into the resting phase (telogen), causing excessive shedding of resting hairs.
2. Alopecia Areata: The immune system mistakenly targets hair follicles, leading to patchy hair loss.
3. Trichotillomania: Characterized by an irresistible urge to pull out one's own hair.

Chronic stress increases cortisol levels, which can negatively impact hair growth by prolonging the resting phase of hair follicles. However, acute stress-related hair loss, such as telogen effluvium, is generally self-limited and reversible once the trigger is resolved. Management strategies include stress reduction techniques, medical interventions, and addressing underlying causes.
