I asked those who conducted the study on twitter and peoples Hair colour prior to incidence of greying was noted, so probably late 20s early 30's, you had to be white and british/irish or northwest European to be asked to be included. They aimed to include people all across the UK.
total Light haired (light brown/blonde/red): 57.2% Dark: 42.8% (dark brown, black)
Interestingly the study found that there is lots of Genes to code for blonde hair, but only 1 gene to code for Ginger hair.

Eye colour is 50% blue, 30% green, and 20% brown roughly according to the largest study of British Eye colour as reported by the dailymail. These are the largest studies on British Hair and eyes to date.
Thoughts?
