Birth of Natural Hair Colour

Hair Follicle

A small cavity made of keratinocytes and melanocytes that extends into the dermis tissue. From here, the hair root develops with a progressive accumulation of keratinocytes that continues to divide in the matrix of the hair follicle located at the bulb area. Melanocytes located in the bulb area then produce melanin pigment, which is transferred to neighbouring keratinocytes, to provide the constitutive hair colour.

Hair Shaft

The visible part above the skin layer. It consists of an accumulated amount of keratinised pigmented keratinocytes of hair follicles (cell gradually lose their nucleus and become filled with keratin, a hard protein), with melanin in its cortex. Pigmentation starts from the bulb area and continues to expand as the hair grows.

Why Does Hair Colour Vary from Blonde to Black?

  • The natural hair colour is the result of melanin deposited along the hair shaft and the cortex (middle layer).
  • Colour shade depends on the amount and distribution of these two types of melanin (genetically programmed): eumelanin (black-brown pigment) and pheomelanin (red-yellow pigment)

Why Does Hair Turn Grey?

The shade of hair depends on the natural pigmentation at the hair bulb. Hair will turn grey when the process of natural pigmentation (as the production of melanin dips) falters.

Reasons for Grey Hair:

  • Frequent dyeing of hair
  • Hair bulb oxidation
  • Long-term sun and UV exposure
  • Gradual loss of melanin due to emotional stress
