Why can't some people grow long hair?

    Some people have difficulty growing their hair beyond a certain length because they have a short active phase of growth. On the other hand, people with very long hair have a long active phase of growth. The hair on the arms, legs, eyelashes, and eyebrows have a very short active growth phase of about 30-45 days, explaining why they are so much shorter than scalp hair. Transplanted hair doesn't know it's in a new location and so eyelash transplants from the scalp need to be trimmed every few weeks to avoid looking like a tarantula.
    By the way, while men tend to prefer women with long hair (ever see a painting of Eve with a buzz cut?), women, especially as they age, seem to prefer wearing shorter hair. After all, long hair on a mature, sophisticated woman can seem about as appropriate as shoveling soup with your fingers. More importantly, our hair tells us a ton about our overall health status, as the growth or loss of hair can signal other malfunctions going on inside of our bodies.

    Everyone has a unique hair growth cycle, which determines how long your hair grows before it falls out. A shorter cycles means you can’t grow your hair past a certain point -- sometimes that’s shoulder length. Although there isn’t much you can do about this, also consider that your hair is breaking off before it can reach its potential length. Getting your hair trimmed every six weeks will eliminate frayed ends and help your hair reach its full potential.
