No, I will have a TAS higher than the GS, to compensate for the crosswind, which makes me travel farther in the air mass than I would on the ground, but that doesn't make the wind vector a headwind, it just stays a crosswind. "To head into wind" does not coincide with having a headwind, as I see it.
Deeday, I think you will find this statement is correct.
OK - perhaps I should have said "headwind component" to make myself absolutely clear ...
