Losing 50–100 hairs a day is normal. Increased hair fall often has a treatable cause — like iron or vitamin deficiency, thyroid problems, stress or illness — while pattern baldness needs specific treatment.
Patchy hair loss, or bald patches with scaling/redness (see a doctor)
Sudden heavy hair loss, or loss with other symptoms (thyroid, anaemia)
Scarring hair loss (permanent if untreated) — needs prompt care
Find the cause first. Many causes of hair fall are temporary and treatable once identified with simple tests. Beware “miracle” hair oils and products. MedDroid gives general information, not a diagnosis.
Frequently asked questions
How much hair fall is normal?
Losing about 50–100 hairs a day is normal. Noticeably more, thinning, or bald patches suggests a cause worth checking.
What causes sudden hair fall?
Stress, illness, fever, childbirth, crash diets, and deficiencies (iron, vitamin D, B12) or thyroid problems commonly cause temporary heavy shedding that usually recovers.
How can I stop hair fall?
Treat the cause — correct deficiencies and thyroid problems, manage stress, and eat well. For pattern baldness, minoxidil (and finasteride for men) are proven. Miracle oils are not.
