What is the name of the dark pigment that causes many animals to be black or dark brown?
I believe you're referring to melanin. Yup, melanin, and it is more than just dark brown and black pigment. Melanin is the primary determinant for all colors found in skin and hair, including reds and blondes. Forms of melanin range from iris color to the ink that a squid produces. Think of grey hair as lacking melanin.
What is the chemical makeup of melanin?
im pretty sure its C16H203N2 IM PRETTY SURE
Which skin layer is the sight of melanin formation?
The melanin in the skin is produced by melanocytes. which are found in the basal layerof the epidermis. You might want to know that because melanin is an aggregate of smaller component molecules, there are many different types of melanin with differing proportions and bonding patterns of these component molecules. Melanin is found in a whole bunch of cells throughout more parts of your body than just the epidermis of skin. (outerlayer).

What color human hair has the most hairs per follicle?
Answer:There is only one hair per follicle, but natural blond hair has the most hairs than red or brunetts.Hair color is the pigmentation of hair follicles due to the two types of melanin, eumelanin and phaeomelanin. Generally, if more melanin is present in the hair, the color of the hair is darker; if less melanin is present, the hair color is lighter. A person's hair color may change over time due to the varying levels of melanin, and some hair can have follicles of more than one color. Due to migrations and global travel, considerable differences exist in the hair colors of individuals, even between individuals of similar ethnicity, creating a greatly increased diversity of hair color.Pigmentationcolor is perhaps the most obvious characteristic of hair, but as far as we know it has no biological function in humans. It does not protect the hair from the harmful effects of sunlight (although hair itself protects the scalp, of course).As we have seen, the color of hair is due to the presence in the cortex of granules of a pigment called melanin, which is formed in special pigment-producing cells (melanocytes) in the hair bulb during the growing phase (anagen) of each hair. The melanin granules lie along the amino acid chains of the proteins, looking under the microscope rather like a string of pearls.Melanin is found in two forms. Eumelanin is the dark pigment which predominates in black and brunette hair. Phaeomelanin is a lighter pigment, which is found in red and blond hair. Many people's hair contains a mixture of the two: the more eumelanin there is in the mixture, the darker is the hair. The mixture (and the shade) varies not only from one person to another, but also across one person's head. The combination of pigments in the mixture is determined by the individual's genes. Differences between dark-haired people are due to differences in the overall quantities of melanins in their hair.Eumelanin granules are oval (elliptical) in shape, fairly uniform in their make-up and quite hard, with sharply defined edges. Phaeomelanin granules are smaller, partly oval and partly rod-shaped.The range of colors produced by melanins is limited to shades of yellow, brown, red and black. Grey hairs contain only a few melanin granules, spread out through the hair. White hairs contain no melanin at all: their whiteness is an optical effect, due to the way they reflect the light. Surprisingly, however, unpigmented hairs look yellow (the 'color' of keratin) when they first grow, and only later turn white.Melanin granules in the cortex of a hairGenetic differencesEthnic differences in hair color are as obvious as are differences in hair type. Most people in the world have dark hair, though in northern Europe blond hair is the most common. Curiously, however, people with blond hair and/or blue eyes are found even in North Africa and the Middle East.
Which shade is the most popular hair color in the world?
A brown pigment to hair is the most common in the world and therefore the most popular as many people have no desire to change the colour of hair they were born with. Hair colour depends upon melanin and this can vary over time.
Does round hair shafts result in wavy hair?
Hair shafts differ in size, shape, and color. In the eyebrows, they are short and stiff, but on the scalp they are longer and more flexible. Elsewhere on the body they are nearly invisible. Oval-shaped hair shafts produce wavy hair. Flat or ribbonlike hair shafts produce kinky or curly hair. Perfectly round hair shafts produce straight hair. The different types of melanin-yellow, rust, brown, and black-produced by melanocytes at the follicle base combine to create the many varieties of hair color, from the palest blonde to the richest black. With age, the production of melanin decreases, and hair color turns gray.Read more: http://www.faqs.org/health/Body-by-Design-V1/The-Integumentary-System-Design-parts-of-the-integumentary-system.html#ixzz0W02WYyMI

What effect does sun have on hair dye?
The main reason is that skin is alive and hair is dead. Melanin is the dark brown pigment produced by your skin to absorb some of the UV radiation from the sun.The melanin in your hair is destroyed by sun and your hair will not produce more melanin to respond to that since it is dead. Your hair will stay lighter until new hair grows in.Skin on the other hand is alive and when the melanin is destroyed by the sun, the skin responds by producing more melanin and thus your Skin get darker.
How many different hair types are there?
Different hair types are thin, thick, short, average, long, oily, kinky, curly, straight, coarse, puffy and dry.
