Some hair facts might calm you if you are having a “bad body hair day”. Everybody has body hair. Few people like it. Most want to get rid of at least some of it. Let me supply you with some little known facts about body hair.
Everything about human body hair is individualistic and mostly hereditary.
The hair growth cycle is unique to every person.
And so is the number of follicles present on every body.
Below you can find some hair facts to ensure you that you are definitely not weird, just human.
Secondary sex characteristic androgenic body hair growth patterns (facial hair, chest hair, pubic hair, abdominal hair, leg hair, arm hair and foot hair) only emerge after the onset of puberty in teenage boys.
Obviously the hair growth pattern associated with secondary sexual characteristics are totally different in females and in males.
Hair grows everywhere except on both lips, palms of hands, soles of feet, backs of ears, peripherals, certain external areas of genitals, inside navel and scar tissue.
Healthy hair indicates health and youth. Hair are nourished from the bloodflow to the dermal papilla of the follicle deep within the dermis.
Diseases and traumas, like chemotherapy for cancer, can cause temporary or permanent loss of hair, either generally or in patches.
Only mammals have hair. It is one of the defining characteristics of their class.
The main component of the human hair shaft is dead protein called keratin.
Hair is dead above the follicle. Fancy shampoos and conditioners can do nothing to fix or prevent split ends.
A little known hair fact is that some medication can cause the development of excessive body hair. This condition is known as hirsutism.
Cutting or shaving the hair shaft after it emerges from the skin surface does not affect the hair growth cycle. Hair doesn’t become more dense and darker just because it had been shaven.
It is untrue that a young boy should put off shaving for as long as possible, because he will become hairier if he starts to shave at a young age.
Influence of genetics on hair facts
No new hair follicles are formed after birth. You are born with the amount of body hair follicles or follicle density you will have as an adult.
It is a fact that baldness are passed on by both the father and the mother’s genes. In rare cases females can also inherit baldness, but it usually do not follow the male pattern baldness.
Frequent shaving does not promote faster re-growth. Blame that on your genes.
Hair colour and texture can be a sign of ethnic ancestry as well as age. Follow this link to read something interesting about the racial characteristics of the blonde people from the Solomon and Vanuatu islands.
Follicle density on the scalp are less than half the follicle density on the male face.
The number of follicles on the head are the same as the combined number of follicles on the rest of the whole body.
Hairy parents will most propably have hairy offspring. Less hairy parents will produce less hairy offspring.
Genetic factors play a huge part in determining individual levels of androgens, hair follicle’s sensitivity to androgens, and thus hair development.
Interesting human hair facts
Curly and/or kinky hair tends to be much drier than straight hair, because the oil has trouble moving down the hair shaft.
Straight hair are shinier and oilier, because sebaceous oils can travel more easily down the hair shaft.
All hair types are affected by the amount of humidity in the air. Water is forced back into the hair shaft and hair returns to its original structure.
Curly hair tends to get frizzy, and straight hair lank, when the humidity rises.
UV light can pass through straight human hair shafts much like light passes through fiber optic tubes.
An interesting hair fact is that hair normally grow at the rate of 0.4mm per day. Hair grows four times faster than human nails.
Androgenic hair are most noticeable in most people of both sexes in just a small number of areas (underarms, pubic region, legs, torso, forearms and face) of their bodies.
Hair whorls have been discovered to be associated with brain development in both humans and animals (mammals).
