About this tool
Log dated hair length measurements, get your real growth rate in cm per month after trims, and project when you will reach a target length.
The Hair Growth Progress Tracker turns a series of dated length measurements into a real growth rate in centimetres per month, adding back every centimetre you trimmed so a haircut does not register as lost growth. Rates are compared against the reference figure of roughly 15 cm of scalp growth a year, about 1.25 cm a month, with 1.0 to 1.5 cm a month covering most adults. It also projects the date you would reach a target length at your own measured rate rather than an average one.

Each entry records what was cut off, so the rate reflects growth rather than what survived the scissors.
Every gap between measurements gets its own rate, so a slow stretch stands out from the average.
Measurements less than 30 days apart are marked, because a 2–3 mm error dominates over short periods.
About 1.25 cm a month for scalp hair, which works out to roughly 15 cm or 6 inches a year and around 0.35 mm a day. Most adults land somewhere between 1.0 and 1.5 cm a month; rate varies with genetics, age, hormones, nutrition and general health far more than with any topical product.
Usually one of two things: breakage at the ends is removing length as fast as the roots add it, or you have reached your terminal length. Terminal length is set by how long your growth phase lasts — typically 2 to 7 years — so a shorter anagen phase caps how long hair can get no matter how patient you are.
No. Growth happens at the follicle in the scalp, and cutting the ends has no effect on it. Regular trims still help retained length, because removing split ends stops splits travelling up the shaft and causing breakage higher on the hair.
Measure dry hair from a fixed point — the same spot on the scalp or the crown — pull it straight without stretching, and use the same section every time. Wet hair measures longer because it stretches, and switching between a front section and the back will produce differences that look like changes in growth rate.
