Hair From Scientific Point of View

Hair is actually dead material when it leaves it's root - otherwise it would hurt very much when your hairdresser works with his scissor. Most people know that, but do you know about these facts:

A blonde head of hair has usually much more strands than red or dark haired heads.

Hair consists mainly of keratin, which is also responsible for the elasticity of fingernails.

A single hair has a thickness of 0.02 - 0.04mm, so that 20 - 50 hair strands next to each other make one millimeter.

Hair is strong as a wire of iron. It rips after applying a force equivalent to 60kg, only after it stretched itself for about 70%.

Even on a good hair day, everyone loses at least 40 to 100 strands.

The average scalp has 100,000 strands, or just fewer than 1000 per square inch.

We are born with all our hair follicles. Some are programmed to grow pigmented hair (as on our scalp) up to 3 feet in length.

In America in '96, 38 million men and 19 million women experience common hair loss determined by heredity.

The trait for baldness can be passed down through paternal or maternal genes.

Hormone imbalance and crash dieting can trigger temporary hair loss.
