- BY KEITH FALKINER

PIERCE Brosnan credits “Guinness” for his enviable hair.

The actor, 72, explained his dietary theory as to why Irish men have luscious locks when asked how his own mane looks so good and noted that his father Tom “had good hair”.

Speaking to Page Six at the premiere of The Thursday Murder Club, Pierce said: “I don't know. It's all in the hair, the old Celtic hair.”
