Some longhairs trim or shave these, but that can lead to another problem which we'll get to later. In spots where male pattern baldness occurs. Many men who are not bald and never will be, still get a slight form of this condition - their terminal length decreases in the areas where baldness usually occurs. A thinness can also manifest itself in these places. For the man whose effects in this area do not show the scalp, he will not look bald, but he may nevertheless find one more annoying set of hairs that just don't want to reach his hair tie.
All materials lose strength over time and eventually fail.
This is due to deterioration from exposure to the elements and due to damage from physical contact with the environment. Put more bluntly, things rot and they wear out, and hair is not immune to this. So you need to understand what makes your hair strong. This means curly and wavy hair has one dimension that is diminished. This narrowness of these hair types makes them weaker for two reasons - one of course is that anything thinner is weaker, but also, this situation makes these strands more apt to dry out.
