How Stress Affects Hair Follicles
Elevated cortisol disrupts the hair growth cycle, forcing follicles into the telogen (resting) phase prematurely. This condition, known as telogen effluvium, often occurs 2–3 months after a stressful event.
Signs and Symptoms
Diffuse shedding across the scalp, increased hair on pillows or brushes, and slower regrowth. The scalp may feel tender or inflamed due to local stress-induced inflammation.
The Science Behind Cortisol and Hair Loss
A 2023 study in the Journal of Psycho-Dermatology found that chronic cortisol elevation shortens the anagen phase and increases DHT sensitivity. Managing cortisol is thus critical to hair regrowth.
Reversal Strategies
Incorporate meditation, regular physical activity, and adaptogenic herbs like ashwagandha or rhodiola. A balanced diet rich in antioxidants supports adrenal health. Topical treatments like minoxidil can accelerate recovery by reactivating follicles.
Expert Opinion
Dr. Jonathan Reyes advises, “Stress-related hair loss is reversible. Addressing the emotional and physiological triggers simultaneously ensures full follicle recovery.”
