Natural Hair Colors

A person's genes determine the hair/skin/eye color since before his or her birth. The determinants for hair color are known as melanocytes. These cells form the natural hair colors, or pigments and distinguish between black, brown, and red. Depending on the percentage of each pigment, the person has blonde, brown, red or black hair. As the melanocytes decay during a lifetime, the hair becomes a dull gray and later on it turns into a whitish color.

The Human Hair

Hair covers the whole body, with the exception of soles of feet, palms of hands, mucous membranes, and lips.
The lifespan of a human hair is 3 to 7 years in the average.
For good hair health, try wholemeal products, eggs, liver, kidneys, vitamin D, herrings, salmon, carrots, green vegetables, and vitamin C.
Pigments give the hair its color. When we age, hair receives fewer pigments and turns gray or white.

And how about this?

Circus artists often display a spectacular trick: "hanging on a plait." A female artist is held up with her hair. High up in the circus tent, she swings upon her whole weight, often with another person or all sorts of circus paraphernalia, all hanging by her hair. Ouch….
