In 1650, here's how you could dye your hair blond

So, are the old ways always the best? I tend to think so, being a grandma. In this particular case, however, I'd recommend more modern methods, although the advice on removing all of the filth before you start is still relevant.

"How to make ones haire to become of a yellow Golden Colour. Take the rinde, or outward parings of Rhubarbe, and put them to steep in Whitewine, or clear Lye; wet a spunge or linnen cloth therein, and anoint your haire therewith, and let them dry before the fire or sunne; the oftener you do this the sooner they will become yellow: note that before you use this, it is good to clear your head and hair from sweat, and all other filth whatsoever."
