Should I dye my hair for headshots?

Try and avoid doing any drastic colouring pre-shoot.

Your look has to last the length of your headshots, so if you are not going to renew your headshots for a couple of years, your hair colour will need to be around for that long.

If you have roots thats need sorting get them done, but think about letting the colour 'settle' for a day or two so as not to look to freshly dyed.
