Hair Loss Red Flags and Medical Signs
Symptom | Possible Cause
Sudden shedding | Stress or illness (telogen effluvium)
Thinning edges | Tight hairstyles causing traction alopecia
Patchy loss | Autoimmune conditions like alopecia areata
If hair shedding lasts over 3 months, it’s essential to seek clinical investigation to diagnose possible underlying conditions including alopecia areata, scalp disorders, or hormonal imbalances.
