My best suggestion is to get Old & have WHITE HAIRS!!
I have no other ideas about bleaching.
I do shave with a 3 headed Norelco, with soap, then I use Edge Shave Gel & my Schick 4 blade razor , both with and against the grain…Carefully!!
Before makeup; moisturizer, consealor, foundation, powder, setting spray and powder.
It is a lot of Work but you have to feel confident…
