Does he want normal red, or really RED red? If it's really red he wants, 'n rage works fantastic. You'd need to get the kind in the box, it has bleach in it also so that you get a more intense color. (The kind in the tube is just for replacing color after it has faded.)
I did my neice's tips with 'n rage ntense pink not long ago. The color doesn't come off on everything, and not much comes out in the shower either.
What I did, was put the color on her tips, then wrap the tips in aluminum foil, and apply heat off and on for 40 minutes. Then I took the foil off and let it cool for a few minutes, then rinsed in lukewarm water. I had mixed up 1 part vinegar to 2 parts water beforehand, and after the initial rinse I dipped her hair in the vinegar/water solution and let it sit for about a minute. Then I rinsed again, conditioned, and that was it! You can get 'n rage at sally beauty supply, and here's a link where you can view the colors: http://haircrazy.info/index.php?menu_id=3&article=23 - http://haircrazy.info/index.php?menu_id=3&article=23
