How does hair get its natural colour scientifically?
There is a dye molecule (melanin) which is added to the hair as it is grown. The concentration of that substance gives hair its color - when the body stops adding melanin the hair goes gray and then white (the true color of hair).
Why are full shells sable?
Full shells can appear sable due to pigment molecules called melanin deposited in the shell during its formation. The concentration and distribution of melanin determine the shell's color, ranging from pale to dark brown. Factors such as genetics, diet, and environmental conditions can influence the amount of melanin deposited in a shell, resulting in a sable hue.
How many amino acid required for synthesis of melanin?
The synthesis of melanin requires the amino acid tyrosine. Tyrosine is converted into melanin through a series of enzymatic reactions.
What creates melanin?
Melanin is created by specialized cells called melanocytes in the skin. Melanocytes synthesize melanin in response to exposure to UV radiation in order to protect the skin from damage. The amount of melanin produced determines the color of an individual's skin, hair, and eyes.
What produces a thick oily substance of melanin?
Melanocytes, which are specialized cells in the skin, produce melanin - a pigment that gives skin its color. When melanocytes are stimulated by exposure to UV radiation or other factors, they can produce more melanin, leading to a darker complexion or tan.
A localized concentration of melanin is referred to as a?
A localized concentration of melanin is referred to as a freckle.

a mole or freckles
A localized concentration of melanin is called what?
a freckle or a mole.
What is a localized concentrartion of melanin?

Which race has the highest concentration of melanin in their skin?
Individuals of African descent typically have the highest concentration of melanin in their skin compared to other racial groups.
Why does your hair appears to be black?
Because of excess melanin concentration
How are black people black?
Skin color is determined by a chemical in the skin called Melanin. This is a pigment that protects the skin from UV rays. The higher concentration of Melanin people have, the darker their skin looks.
Can tattoos tan?
No, because a tan is your skin having a higher concentration of melanin in it, the tattoo ink doesn't change.
Why do some hairs have black roots?
Hairs have black roots due to the presence of melanin, a pigment that gives hair its color. The amount and type of melanin in the hair follicle determine the color of the hair root. Black roots indicate a higher concentration of melanin in the hair follicle.
What substance is responsible for hair color?
Melanin is the substance responsible for hair color. There are two types of melanin: eumelanin, which provides black or brown colors, and pheomelanin, which provides yellow or red colors. The combination and concentration of these pigments determine an individual's hair color.
What is the function of melanin?
Melanin gives color to the skin, hair, and iris of the eyes. Levels of melanin depend on race and amount of sunlight exposure. Sun exposure increases melanin production - to protect the skin against harmful ultraviolet rays. In addition, hormonal changes can affect melanin production.
State the specific location of melanin observed in dark skin?
Melanin in dark skin is primarily located in the basal layer of the epidermis, where it is synthesized by melanocytes and transferred to surrounding keratinocytes. This results in a higher concentration of melanin in the skin, providing protection against UV radiation and giving dark skin its characteristic color.
