if i zoomed into my hair roots with a super strong camera, how fast would I have to speed it up to watch my hair grow?

probably like 50x or less. depending where the hair is I guess

Replying to

on average hair grows 15cm/year. For a 30 sec video, speed up by factor 7000-15000 for it to be somewhat interesting to watch.
