What lead-free products are there for men to hide gray hair, gradually?”
Here’s a great article that explains this much better (more concisely) than I ever could: http://www.menessentials.com/oxid.php/sid/x/shp/oxbaseshop/cl/info/tpl/hair_dye.tpl You need to pick, either a little lead and a little color, or no lead & a lot of color. I’m not an expert in this field, but a family friend uses dye & I asked him. He said the graduals were too much to deal with and he uses Just For Men. Hope this helps your decision making prcess!
