shampoos / conditioners

[TddWil@aol.com]

What helps a rubbed out mane grow in quicker? (rubbed reaching thru fence, 
not a skin problem) Just conditioners/oils or would a feed supplement help? 
This is a flaxen mane and the hair is real fine and dry. Also, do any 
shampoos actually whiten a grey horse? What about shampoo to enhance 
color(without dye, like QuickColor)?
Just trying to keep these turned out critters looking spiffy for rides/buyers.
