About this tool
Log daily shed hair counts, separate wash-day spikes from real shedding, and compare your average against the typical 50-100 a day range.
The Hair Fall Count Log records how many hairs you shed each day and averages them across the whole period, so the figure can be compared against the normal adult range of roughly 50 to 100 hairs a day. Wash days are logged separately because hairs that detach on dry days stay caught in the hair until the next wash, which is why a single wash-day count of 200 usually means nothing on its own. An optional trigger date maps the 2 to 3 month delay and roughly 6 month settling pattern typical of telogen effluvium after illness, surgery, childbirth or sharp weight loss.

The headline average spreads counts across calendar days, so infrequent washing does not fake a shedding problem.
A rolling seven-day average and a week-on-week comparison show direction rather than noise.
Enter the date of an illness or major stressor and see the window when post-trigger shedding usually appears and settles.
About 50 to 100 a day for an adult scalp. With roughly 100,000 hairs on the head, 100 a day is about 0.1% — and because hairs are replaced continuously, that rate does not thin the hair.
Because a hair that has finished its cycle stays trapped among the others until something dislodges it. If you wash every fourth day, that wash releases four days of shedding at once, so a count of 250 after four dry days is about 62 a day — inside the normal range. Judge the average over the period, not the peak.
Book an appointment if shedding stays above about 100 a day for more than a few weeks, if your parting is widening or you can see scalp through the hair, if the loss is patchy or circular, or if there is scalp pain, scaling or scarring. Several common causes — thyroid disease, iron deficiency, and medication side effects — are identifiable on simple tests and treatable.
That delay is the signature of telogen effluvium. A shock such as high fever, surgery, childbirth, crash dieting or severe stress pushes an unusually large share of follicles into the resting phase at once, and those hairs are only released about two to three months later. It is usually self-limiting and settles within about six months once the trigger has passed, but persistent or worsening shedding should be assessed.
