What counts as normal hair fall?
Losing 50–100 hairs a day is completely normal — each follicle cycles through growth (2–7 years), transition, and a resting phase that ends with the hair shedding. Seeing hairs on your pillow or brush is not by itself a problem; the question is whether shedding has clearly increased from your baseline and whether density is visibly changing.
The two most common patterns
Telogen effluvium — sudden diffuse shedding 2–3 months after a trigger (illness, fever, surgery, childbirth, crash diet, severe stress). It looks alarming but usually resolves on its own within 6–9 months once the trigger passes.
Pattern hair loss (androgenetic alopecia) — gradual thinning at the temples and crown in men, or widening of the part in women, usually with family history. It progresses slowly; early treatment (clinically proven options a dermatologist can prescribe or recommend) preserves far more hair than late treatment.
Nutrition really does matter
Hair is protein (keratin), and follicles are among the most metabolically active tissues in the body. Deficiencies of protein, iron, zinc, and vitamin D are common, testable, and correctable contributors to shedding — one reason crash diets so often show up in the hair 2–3 months later.
When to see a dermatologist
- Bald patches, scalp pain, redness or scarring — these need prompt assessment
- Eyebrow, eyelash or body-hair loss alongside scalp loss
- Shedding beyond 6 months with no obvious trigger
- Rapidly visible thinning at any point — earlier treatment means better results
