OK this is the big question..
Some answers you can give to detractors :
1) This was a long period of war, sometime they made bread themself, so they use flour, so the hairs were powdered
2) This is the depiction of the late son of Earl of Santenay, the father was a dandy and on his deadbed make his son promised to always powder is hairs
3) Paint it blak and drybrusk for highlight so you can say Yes it's powdered
No it's only highlight works
I remember somebody telling me once that a saber was not accurate and shorter then the standard issue . I answered : this is a well known event, at the
battle of Sulosinskin; Paul Rocemdaud had the tip of his sabre broken at he eve of the batte during a skirmish, at the field forge they had just the time to rework a new tip . My detractor was stunned by wat he thought an accurate knowledge of history and I left him mouth wide open . ( He must still be there )
