Blonds not ditzy, in fact they’re com­plex

The Sunday Times - - NEWS -

BLONDS may have a ditzy rep­u­ta­tion, but their lighter locks are far more com­plex than first thought.

True blond hair re­quires some 200 ge­netic vari­ants, com­pared with 60 for brown hair and even fewer for the world’s red­heads.

In one of the big­gest stud­ies of its kind, sci­en­tists have an­a­lysed DNA from 39,397 blond women and men. Only 12.7 per cent of women have pure blond hair, and 9.9 per cent of men.
