We all have it, and the majority of the female population wouldn’t mind admitting that they obsess about it, but many of us don’t know the facts about human hair. Here we will go through 10 amazing facts you may not have known about hair.
The human body is covered from head to toe in different types of hair, some visible and some virtually invisible, however there are a few parts of the body that produce no hair what so ever, and these are the palms of our hands, the soles of our feet and our lips.
Pulling a hair out at different times during the hair cycle impacts the body indifferent ways. If you pull a hair out at the end of its life cycle it will not hurt at all and you are unlikely to feel it, whereas if you pull a hair at the start of its cycle it will be felt.
Hair grows at a much faster rate than many believe, an incredible 3mm every single day. So over a month you are look at between 3-4 inches of growth. That means in a year you potentially could grow your hair by a massive 36inches! Having said this, this does not take into consideration the amount of strain we put on our hair over that year, with heated styling products, hair dyes etc, so for many of us this will not be true.
The amount of hairs each human has can vary quite dramatically, with some having very thin and others very thick hair. On average we have between 100,000 to 150,00 hairs on our head.
Each individual hair has its own life span. The average life span of a single hair can be anywhere from 4-7 years.
Have you ever come out of the shower and brushed your hair only to find that you are pulling out what seems like quite a lot of hair? That is because on average we loose between 50-100 hairs per day. So that is why you will find yourself having to regularly empty your hairbrush of dead lost hairs.
To match the fact above, when these hairs come out they are not gone forever as a new hair will immediately begin to grow in its place. This can happen up to 20 times in a lifetime which is why when the 20 times has passed, people begin to slowly loose their hair, as the hairs that come out can no longer be replaced.
The shape and size of each hair varies from person to person, and more noticable from origin to origin. For example African-American, Asians and Causasiona will all have very different shapes and sizes of hair which is why there is a noticable difference between these hair types
Even hair that is 100% straight is actually curly, even if only slightly. All hair twists at it grows. What differentiates the curliness of hair is how many twists the hair makes as it grows. The number of twists in a given length will determine how straight or curly hair is.
