Genes and Hair Growth

Hey everyone, I posted a ‘Curly Hair Growth chart” a few weeks back, which gives you an overview on the average growth of hair. This post goes more in depth on hair growth.  


The amount of time it takes to grow out your hair depends on the health of your hair, genetics, and how long you want it to be. The regulation of human hair growth is one of the most mysterious of biologic events. Genetic factors are responsible for the density, length, color and texture of hair. As a general rule, the longer you wait the longer your hair will be. However, everyone has a terminal length for their particular hair. This is the point where your hair simply refuses to grow longer for long stretches of time. This can be caused by unhealthy hair, the way you treat your hair, or simple genetics.


Average Growth 


 Each strand of hair on the human body is at its own stage of development. Hair follows a specific growth cycle with three distinct and concurrent phases: anagencatagen, and telogen phases. Each phase has specific characteristics that determine the length of the hair. All three phases occur simultaneously; one strand of hair may be in the anagen phase, while another is in the telogen phase. Once the cycle is complete, it restarts and a new strand of hair begins to form. The hair of the average person grows approximately one half inch per month. This adds up to six inches of new hair per year. If you use this as a rough guide to your hair growth, you can estimate how long it will take you to get to your desired length. Keep in mind that there are many factors that can alter the average hair growth. Most of these factors impair hair growth instead of enhancing it.

Health vs Hair Growth

A balance must be reached if you wish to grow out your hair and keep it healthy at the same time. Since hair grows approximately one half inch per month, a one half inch trim every month will keep it at the same length. If you are growing out your hair, cut the ends one half inch every three or four months. This keeps the ends healthy while encouraging hair growth.


Diet and Genetics


Healthy people tend to have healthy hair. If your body is not getting the nourishment it needs, it will not waste energy growing hair. If you are serious about growing out your hair, you need to take care of yourself. Drinking plenty of water, getting lots of sleep, reducing stress, and eating a well balanced diet are all proven ways to increase hair growth. Some people are just genetically predisposed to have rapid hair growth. The hair of other people just stops growing at a certain point. This is called the terminal length. Either way you are stuck with your hair. There is nothing you can do about your genetics.
