Q.
Answer
http://en.wikipedia.org/wiki/Red_hair
red hair (also referred to as titian or ginger hair) varies from a deep burgundy through burnt orange to bright copper. It is characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin. Approximately 1% to 2% of the human population has red hair. It occurs more frequently (between 2% and 6% of the population) in northern and western Europeans, and their descendants, and at lower frequencies throughout other parts of the world. Red hair appears in people with two copies of a recessive gene on chromosome 16 which causes a mutation in the MC1R protein. It is associated with fair skin color, lighter eye colors (gray, blue, green, and hazel), freckles, and sensitivity to ultraviolet light.
ORIGINS
Red hair is the rarest natural hair color in humans. The pale skin associated with red hair may have been advantageous in far-northern climates where sunlight is scarce. Studies by Bodmer and Cavalli-Sforza (1976) hypothesized that lighter skin pigmentation prevents rickets in colder latitudes by encouraging higher levels of Vitamin D production and also allows the individual to retain heat better than someone with darker skin. Estimates on the original occurrence of the currently active gene for red hair vary from 20,000 to 100,000 years ago. Red hair is caused by a relatively rare recessive gene, the expression of which can skip generations

Less than four percent of the world population has naturally red hair. That is less than two percent in America. The gene for Ginger hair was discovered in 1995 and this discovery got little attention. This is not consistent as red heads have gotten lots of it. Professor Jonathan Rees conducted a study of redheads at Edinburgh University.He identified the"gene for red hair" the melanocortin 1 receptor (MC1R), found on the 16th chromosome. He found that this single gene was responsible for red hair.
Red hair is a genetic mutation, and is seen on the heads of only four percent of people. Most of these exist in the U.K., the Republic of Ireland, and Australia. The highest percentage of natural redheads in the world is in Scotland (13%), followed closely by Ireland with 10%. In the US, about 2% of the population are natural redheads.
Red headedness is, genetically speaking, a recessive trait. It may appear after several generations of darker hair. Redheads do NOT turn grey. Red hair turned sandy, then white. They are also found to loose their color later in life than people carrying other hair colors.
The first human redheads walked this earth about 50,000 years ago in Africa and then spread throughout Northern Europe. The country name of Russia means "land of reds" in honor of a redheaded Viking by the name of Rurik.
The first redheaded British monarch was a woman. Boudicca was a Celtic warrior was led her people, the Icenti, against the Romans in the C.E. 60âs.
Belief that redheads are witches is a folk belief in Germanic culture. From 1483-1784 thousands of suspected witches were nearly always stripped and searched for âmarks of the devilâ. These included any âabnormalityâ such as freckles, moles, warts, and birthmarks. Red hair was certainly considered an abnormality. Considering the freckle factor for redheads this was a deadly and shocking horror. Somewhere around 45,000 women were tortured and murdered usually by burning at the stake or by drowning.

Genetics of Red Hair
Part of the allure of red tresses is its rarity: red is found in less than 4 percent of natural hair colors throughout the world. The majority of redheads are concentrated along the edges of both eastern and western Europe, most notably in Scotland, England, and Ireland; countries that have become easily associated with flowing auburn and ginger tresses. In the United States, less than 2 percent of individuals have naturally red shades of hair. The exclusivity of red is due to its genetic makeup: the red chromosome for hair color is a recessive gene, meaning that an individual must inherit the gene from both parents in order to have red locks of any shade.
Redheads have other genetic traits related to their hair color. Red is found predominantly on individuals with very fair skin who are typically more sensitive to ultraviolet radiation, meaning they sunburn easily, and their hair may also need additional radiation protectants. Each individual red strand is thicker than its blonde, black, or brunette counterparts, but redheads typically have up to 30 percent fewer strands on their heads, making hair loss and thinning a potential concern.

If i dyed my red hair brown, would the colour come back again?
Q. I have natural red hair, if i dyed it brown, will my natural colour come through again afterwards? ive heard it words differently on that colour
Answer
Of course not, that will only take you longer to get to your natural color.
Celebrity wears two-tone hair dye all the time, trying to grow out their dye. They call that the ombre style.
Style meets chemistry meets biology: We're talking hair coloring.
Playing with chemicals is not like playing with clothes, or doing a manicure, there are penalties for playing chemicals in the lab. Even hair color experts at the salon are not rocket scientists, they do a bang up dye jobs to their clients or their own hair.
Chemicals can enter the body through the skin.

London, Feb 20, 2013 I've been saying that since 2009.
Hair dyes, which include home hair colouring kits and those used at pricey salons, are linked to deadly cancer-causing chemicals, warn scientists. In 2009 the Mail revealed that women who used hair dyes more than nine times a year had a 60% greater risk of contracting blood cancer.
A year later the European Commission banned 36 hair dyes which put long-term users at risk of bladder cancer. < < < <â¨
Google: Teen 'feared she would die' after reaction to hair dye
The allergic reaction was caused by a well-known brand of semi-permanent hair dye Chloe used to turn her hair black for a Halloweâen party. . . . . called for beauty bosses to ban hair dye chemical PPD (para-phenylenediamine) from the shelves. 11-04-11
The chemical is not new and is present in a number of brands of dark hair colours, acting to help adhere the dye to the hair so that it doesn't wash out. Itâs made from coal tar and is used in both permanent and semi-permanent hair colours. Itâs well-known to be a cause of serious allergic reactions -- including something called contact dermatitis which can lead to rashes, blisters, and open sores.
PPD is sometimes added to black henna tattoos and that using them is not safe. Allergic reactions usually begin within two to 10 days following application. One bad reaction can lead to sensitivities to other products such as hair dye, sunblock and some types of clothing dyes. Oftentimes, it's using the product a second or third time. Skin specialist Najjia Ashraf reveals that there are barely any dyes that donât contain this toxin; even the ones who claim they donât, are not being honest. âBig brands often escape the blame by suggesting they are ammonia-free. However, ammonia and PPD are two very different things and PPD is present in nearly every dye because it is what gives off the colour,â she explains.
Google: A 38-year old mother left in a coma after using hair dye. SHE DYED HER HAIR MANY TIMES BEFORE, USING THE SAME BRAND. The British woman who went into coma after a reaction to hair dye has died after a year. Updated 11-25-12. The woman suffered a heart failure, struggled for breath and became unconsciousness. Her family blamed paraphenylenediamine, a chemical found in hair colour. Her family has now called for paraphenylenediamine to be banned from home dye kits. In 2000, a 38-year-old Indian-origin woman from Birmingham, Narinder Devi, died after an allergic reaction to hair dye.
Permanent black hair dye is linked to causing leukemia and lymphomas.
