      So that old women can draw eyebrows with pens…? 🙂
      http://en.wikipedia.org/wiki/Hair_follicle – they do continue to grow, but there is huge individual variability in cycles apparently. Thanks for that question though, I learned a lot today

      They are all in a continuous cycle of growth and regeneration, it’s just that for eyebrows and eyelashes, the cycle is shorter (about 4 months) and for hairs it takes years.

      Hope that helps 😉

      They do, but they hopefully fall out before they get too long! We’re continually growing new eyelashes, to replace the ones that have fallen out.

      All our body hair (head and eyebrows/lashes) grows to a set point where it won’t grow any longer. Eyebrows/lashes grow slower and have a shorter ‘set point’ than head hair so they seem to stop growing much faster, but if you let your head hair grow, it would eventually reach a point where it stops growing as well. The ‘set points’ are different for different people – explaining why some people have naturally long eyelashes and why my mum can’t grow her hair past her shoulders! 🙂
