Causation Of Hair In Red Color

Hair has long been a topic of interest to people throughout the world. The color, texture, style, and length come up often in conversation. There is one particular coloration of hair that is almost universally associated with one region of the world despite it actually being a part of many. The naturally red-haired human being is a rare creature. They are often referred to as “titian” or “gingers”. While science has a very specific reason for this physical trait there have been many other reasons cited for its existence for hundred of generations. Most of these folklore explanations have been negative and often incredibly insulting.

Scientifically speaking red-haired has been determined to be caused by a single gene on the sixteenth chromosomal strand of human DNA. This recessive gene affects the MC1R protein which determines color based on two chemicals pheomelanin and eumelanin.

These two types of melanin intermix to create protein strands which eventually becomes hair color. Pheomelanin generates lighter colors such as red and blonde hair. Eumelanin generates darker colors such as black and brown.

When these two melanin types appear they determine the coloration of the hair. With a very low Eumelanin amount and a higher Pheomelanin production hair will become red. There are several differing thoughts among the scientific community as to the origin of these gene that range from the largely discounted acquisition of it from intermixing of homo sapiens sapiens with homo neanderthalensis to negative selection. The red-haired gene evidenced in that cousin species to modern cro-magnon humanity has been determined to be a different type of mutation that the one that exists within homo sapiens sapiens. Negative selection is a concept that dictates that the red haired mutation survived in northern Caucasians because the environment didn’t select against it. Red hair and fair skin would have caused incredible hardship in an area like Africa but in the far north it didn’t cause as many issues and the fair skin simply aided in the acquisition of vitamin D.

While non-pathological genetics are considered the general reason why this rare hair coloring exists it is not the only reason. There are actually several types of genetic disorder, disease, and injury that can cause hair to turn red.

A disease known as Kwashiorkor and similar protein deficiencies can cause hair to turn red. Severe malnutrition will cause the hair to change from a darker color to red or possibly blond due to lack of protein and chemical shifts within the body as it tries to stave off starvation.

There is a type of albinism known as “Rufous” albinism that afflicts individuals of African Decent as well as some from New guinea that also causes red hair and red skin to occur. It is also generally found in individuals with a deficiency in pro-opiomelanocortin. This is a precursor polypeptide that controls several factors of physicality. Mutations in this gene have been cited as being causes for obesity and adrenal insufficiency as well as pigmentation it can cause.

      I'm a natural red head and I absolutely love it! Yeah, not being able to naturally tan and having to use fake-bakes in the summer can be annoying, but it's worth it. My colour is aburn but with a lot of red and gold. The natural highlights (I have never dyed my hair or gotten highlights) are a goldish red. It is naturally curly, but straightens very well. I'm a very lucky girl! Since my eyes are a green-blue-and-gold colour, they compliment my hair very well. Again, I'm very, very lucky because there is only one other red head in my family! Redheads are also very lucky because instead of going grey like brunettes and blondes, we go sandy brown, then white :) GO GINGERS! :P

      I also have red hair.. nobody else in my family (and i'm not adopted) has red hair.. and when i say nobody not an aunt or cousin. I'm not irish either i'm 25% each german hungarian italian & french. My hair is wavy/curly and i get natural highlights but put more blonde in. I tan pretty easily except my face doesn't get very dark. My eyes are an ocean blue they vary from blue, blue/gray, to blue/green. Anyone with similarities?

      Oh man, seriously.. If I wasn't a brunette... I'd wanna be a redhead; hands down! Except I wouldn't put any blonde highlights in it. No way! I'd just let it excite everyone in it's bold beauty.. A color psychologist would tell you that this is no surprise: red is the color that makes people hungry. Red also makes people excited, energetic, and increases the heart rate! I know what I'm gonna die my hair later on in life.... ;)

      what you should do is not let anyone know it bothers you and eventually it wont - use your hair to your advantage - wear colors like blue ivory and brown they're they best for redheads.. and plus they're probably just jealous once you get older you'll see that people would kill to be a natural redhead!

      and i've never the pubic hair comments either. i mean who really gives a crap what color your hair is? black brown blonde red? a lot of people shave it off anyway... i think red would look better than a thick,dark brown or black anyway which pretty much everyone else is...!

      I am a 13 year old natural redhead with frizzy hair that i tame by straightening. Guys in my grade make fun of it by calling me a "ginger". At first i was pretty offended and upset by this but now i have learned to ignore it. Also, if you have conversations about who you will look good with they probably won't say anyone because they think that you have to have the same hair color as your partner, which isn't true!!!!!! Y'all are lucky for those of you who said you have blue/green eyes! I'm thinking of getting eye contacts so i can have gorgeous eyes! My eye color is copperish brown that have a fiery color mixed in, but i'd much rather have blue eyes! My legs, arms, and especially stomach can get pretty tan, but my face never does!! I don't understand why, but this summer my goal is to get an all over tan, fake or not. I love being a redhead because i'm always remembered and i stand out! In fact, at our cotillion, the guy looked through the crowd and chose MEEEEE to be his dance partner, and he was the instructor! I got to dance infront of everyone! THANK YOU RED HAIR!!!! <3

      kelly your eyes sound like theyre very pretty.. and don't worry too much about tanning - i used to be like that but tanning is overated and your skin will be with you forever while a tan fades. and yes one of the best things about being a redhead is being able to stand out.. good for you=)

      If you need to tan use the moisturizers. They're alot more even than spray tan and sun tans and it's good for skin. They even have sunblock in them (for which you will thank yourself later). It isn't for everybody though, do a patch test on your jawline or something if you have sensitive skin. Make sure you're not allergic first. I can't use tanning moisturizers because it gives me pimples because I have oilyish skin, but if it works for you, go for it.

      I'm 23 and I LOVE my red hair. I've realized growing up that other females my age don't approach me, but guys of every age and race are always approaching me. In my experience guys LOVE red hair. I've been told that people think redheads are scary and hard to approach. I don't feel scary. I'm really nice. No one really made fun of my red hair but they made fun of my freckles quite often along with being really pale. I'm extremely pale with naturally really pink lips. I barely have any freckles compared to many redheads, or freckled people in general. People actually TELL me that I dye my hair because I dont have enough freckles to be a redhead. I think the fact that teachers/adults always told me how beautiful my hair was, made other girls insecure. Anyone older than me loves my hair, the older I get the more people my age appreciate it. It grows insanely fast and is wavy. It's somewhere between a strawberry blonde and a copper color with an orange tone. I often tell people it's not red, it's orange. I have green/blue blue blue/grey eyes with a few golden specks mixed in. Being a redhead is a huge part of my identity. I don't have to say or do anything, and people notice me. I recently started taking Ultra Nourish-Hair and a little over two weeks into it I've found quite a bit of new growth scattered around, unfortunately a lot of the new growth is shiny white! And yes, I did yank a few out :) I'm really upset and I'm going to stop taking the supplement. I'm a really low maintenance mascara and chapstick girl, but if I'm going to be excessively white in my mid 20's I'll become a crazed hair dying lady. I love my hair color too much to have it taken away! Any advice?
