hi Carol, my friend said his head hair turned dark brown in color. he did not dye it. he is originally blond. his eyebrows, lashes, and pubes remain blond. do you know the reason why his head hair turned dark brown ? thanks.As for the eyebrows,most blondes with ash blonde and lighter shades of blonde,will darken their brows slightly,as to give some definition to their face,as blonde brows are very light,and some like to have just a tad of color.
