Blonds not ditzy, in fact they’re complex
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.
