  • The cold truth
    It's said that rinsing your hair with cold water will make it shine. But that's not science. Let us show you why.

Did you know?

  • The average human head has 80,000 to 150,000 hairs.

  • Hair can't heal once damaged, so it's important to protect it.

  • Hair is typically 79% keratin, 17% water and 4% fats, oils and pigments.

The life cycle of a hair is typically 2 to 7 years.

Hair is the second fastest replicating tissue in the human body.
