How fast does hair actually grow?

About one centimetre a month, or roughly half an inch. That number barely moves — not with supplements, not with haircuts, not with the season.

About a centimeter a month, half an inch. That's the number. And it barely moves. Not with supplements, not with a haircut, not with the season. Which means every Honest Hair timeline is measured in months, not weeks. If you want shoulder length from a chin length cut, that's about a year. Anyone selling you faster than that is selling something.

It is why every honest hair timeline is measured in months. Going from a chin-length cut to shoulder length is about a year. It is also why judging any change by memory fails: the change is slower than recollection is reliable, which is the whole argument for measuring instead of remembering.

The honest next step for most hair questions is a measured look at your own scalp. The Uberhair hair check is free, takes about 3 minutes from your phone, and your photos go to the doctor you choose.
