The readings, group by group
The table lists each group with its sample size and its measured resting share. The last column is worked out from that share and the group's density, over a 90-day resting phase. Each row carries its own sample size, so the figure can be read against the group it came from.

The calculation, written out
The resting share is the measured input. To turn it into a daily figure for one square centimetre of scalp, two more things are needed: how many hairs grow in that square centimetre, and how long a resting hair stays in place before it is shed.
shed per cm² per day = density (hairs/cm²) × resting share ÷ 90
Worked example: a group with a density of 200 hairs per cm² and a resting share of 10% gives 200 × 0.10 ÷ 90 = 0.22 hairs per cm² per day. The example uses round figures to show the arithmetic; it is not one of the groups in the table above.
The 90 is the resting (telogen) phase read as three months — the time a hair that has stopped growing stays in place before it is shed. Three months is taken as 90 days, and that one divisor is used for every row in the table; no row is worked out on a second basis. Read as two months (60 days) instead, each daily figure would rise by half — the Russian row would read 0.27 rather than 0.18 — so 90 is one reading of the resting phase, not a fixed value. The density figures are not repeated here: they are the readings on the hair texture chart. The daily figures are calculated from two measured inputs, the density and the resting share; they are model values, not a separately counted shed rate.
What the range means
The resting share is the fraction of hairs that have stopped growing and are waiting to be shed. Measured group by group it is not one figure: Danish, Polish and Russian hair rested at 8%, Thai hair at 14%. Because the daily figure is built from that share and the group's density, the two do not move together — the group with the highest resting share is not automatically the group with the highest daily figure.
The readings come from measurements of 2,249 healthy young adults (18 to 35 years old) across 24 ethnic groups on five continents. Within that same cohort, men rested at 12.2% against women at 10.1% (p < 0.001; 1,065 men and 1,184 women). Readings collected 8 October 2026.
Does one resting share fit every group?
No single figure fits the whole set of groups. The 24-group range runs from 8% to 14%, and the daily figure worked out from it runs from 0.18 to 0.30 hairs per cm² per day. A share in the middle of that band is a population figure, not a target that any one person should match.
