hi i am doing someones hair next week for a television show. what is
the best way to make the person look old? he has blonde hair now, i am
planning on making his hair very short and grey. i am thinking about
using white bleach and leaving that on for 15 - 25 minutes, washing
that out, then puting in violet toner until i get a grey look. what do
you think?

I think your client is a really brave dude.

If the hair is blond already, you might be able to use just a drabber,
without pre-bleaching.

seems kind of extreme...can't you use a wig??
