I want to share with you some knowledge about hair. Hopefully, you will find this information interesting and useful. Now days with all the tools, products and chemicals, we can achieve just about anything we want with our mane. However, not everything we do to our hair is good. I will probably have to give a series about hair because of all the information there is, it would make just one post extremely overwhelming.

I first want to start off with, “What is the purpose of hair?” I’ll give you four top reasons for its purpose. The purpose of hair is first and foremost, it was designed to be protection for our body. Protection in the means of being a thermal regulator. Hair regulates body temperature, being in cold environments makes our muscles contract, causing them to pull the hair into an upright position. When this happens, the erected strands trap air and serve as insulation to protect the body from the cold. This is why when a person who has long, or thick. hair feels warmer than someone who has little or no hair. Hot temperatures give an opposite effect. As sweat glands secrete sweat, it evaporates to cool the body. This effect makes the muscles relax and causes the hair to lay flat in order to release heat.

The second very useful function of our mane is it extends our sense of touch. It is astounding to know that we may feel an object before it even touches our skin. In 2012, a study was published by John Hopkins University School of Medicine. In that report, it stated how the brain processes and collects information through hair on the skin. David Ginty, Ph. D., professor of neuroscience at John Hopkins, says more than 20 classes of mechanosensory nerve cells in the skin is what detects everything from pain to temperature. I find it absolutely amazing how the design of our body can physically detect the feelings of the changes from our atmosphere, to knowing there is an object near you before it comes in contact with your skin.

Now, for the third reason of how our hair serves a purpose. Having body hair which covers almost our entire body except for the palms of our hands, soles of feet, and lips. Aside from providing cover from the environment, body hair such as eyebrows, eyelashes, nose, and ear hair helps keep dust and foreign matter out. This is how we are able to feel something near us without it touching us. Those tiny, itty-bitty hairs that cover our body are called vellus hairs. Vellus hair is also referred to as baby hair, or peach fuzz, and is translucent and much thinner than the hairs on your other body parts.

The fourth reason why hair is important is it gives you a sense of identity. For many centuries, hair has been a significant part of a woman’s physical feature of adornment and attraction, which it still serves the same today as such. Hair is the first feature on a person’s body that most people see and judge on its appearance.

Now, you have four reasons why we have hair and its design of use for us. It serves a mighty and essential purpose for us. It is important to take just as great care of your hair as it is for your outer and inner body. Everything that we do to our body has a great effect on our well-being. No matter if your hair is long or short, you still have those sensory follicles. I may suggest being aware of what you are applying to your hair.
