Covering White or Grey hair

  • Identifying the percentage of white hair
  • The amount of white hair on a head is described as:
  • Percentage (%) of grey hair
  • So, if every second hair on the head were white (half the total number) the head would be said to be 50% grey
Goldwell measure percentage of white hair as follows:
  • 10-30% white = small amount
  • 30-60% white = half/half
  • 60-100% white = large amount

N, NA & NN shade

  • These are specially designed for coverage on white hair
  • If you have white hair and require coverage your formula must contain a percentage of N shade or NA shade
  • NN is designed to cover resistant white hair
  • Do not comb through a NN shade onto hair that is already coloured

White or Grey Coverage

  • You would recommend permanent colour for a client with over 80% white hair
  • A clients skin tone should compliment the colour of their hair, when possible it should look natural
