What You Need To Know About Hair

• Every day the average person loses 60-100 strands of hair.
  Your hair loss will vary in accordance with the season, pregnancy, illness, diet and age.
• Your Hair only grows 0.3 to 0.5 millimeters each day.
  Or about 1 cm every month. So this means that it can keep this life diary for a long time – for months or even years
• The average human has 100,000 hair follicles.
  Hair color determines how dense the hair on your head is. Blond hair people usually have more hairs than people with red or dark colored hair.
• The lifespan of a human hair is 3 to 7 years on average.
  Your hairs will likely get to see several different haircuts, styles and even possibly decades before they fall out on their own.

Hair Structure:

• Cuticle 
  Thin and colorless, average as a protector of the cortex
• Cortex
  Provides strength and both the color and the texture of hair
• Medulla
  Is core, presents only in large thick hairs.

Hair Root Is Indeed Alive.
It is located below the epidermis while the hair that appears above the epidermis is only made from dead cells.

The dermal papilla contains receptors for male hormones and androgens.
Angrogens regulate hair growth and in scalp hair Adrogens may cause the hair follicle to get progressively smaller and the hairs to become finer in individuals who are genetically predisposed to this type of air loss.

The Hair Growth Cycle

• 80% – 90% (2 – 6 years) Anogen
  Growth Phase: Approximately 85% of all hairs are in the growing phase at any one time. The Anagen phase or growth phase can vary from two to six years. Hair grows approximately 10 cm per year and any individual hair is unlikely to grow more than the one meter long.
• 1% – 2% (Several Weeks) Catagen
  Transitional Phase: At the end of the Anagen phase the hairs enters into a Catagen phase which lasts about one or two weeks, during the Catagen phase the hair follicle shrinks to about 1/6 of the normal length. The lower part is destroyed and the dermal papilla breaks away to rest below.
• 10% – 15% (5 – 6 weeks) Telogen
  Resting Phase: The resting phase follows the Catagen phase and normally lasts about 5 – 6 weeks. During this time the hair does not grow but stays attached to the follicle while the dermal papilla stays in a resting phase. Approximately 10 – 15% of all hairs are in this phase at an one time
