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.
