A comb with extra teeth-spikes sticking out of the first set of teeth-spikesm at a slight angle, with teeth sticking out of them, and so on.
Maximum hair straightening.
See link for my attempt at illustrating.
ADDENDUM:
The idea is to have enough teeth that each hair is separated from each other hair.-- DesertFox, Jun 02 2006 Fractal Comb http://img299.image.../fractalcomb3vs.png [DesertFox, Jun 02 2006] Would it straighten? Could you move it through hair at all?-- phundug, Jun 02 2006 I like...-- po, Jun 02 2006 good for teasing hair too-- pigtails_and_ponies, Jun 02 2006 If it is truly fractal, it will be a comb with poorly-shaped rough teeth. Which would pull hair and hurt like crazy. Which might work for combing a shedding dog, although we have tools for that already.
I'd fishbone it for being non-workable and non-buildable, but maybe you mean it to be exactly what you illustrated. Which is just a funny-designed comb with the problem that Nwizad points out. Wait, it says, "And so on." I'm fishboning.
By the way, people used to use fishbones as combs. Supposedly. Have one.-- baconbrain, Jun 03 2006 The idea is to have enough teeth that each hair is separated from each other hair.-- DesertFox, Jun 03 2006 Feathers are built like this. but each barbule is spiraled.-- JesusHChrist, Jun 03 2006 Ow.
<enjoys receding hairline more fully now>-- 2 fries shy of a happy meal, Jun 03 2006 You'd probably have to use a conventional comb before using this one. Other than that, I like.
You could even put the conventional comb opposite this one: use one side, flip it over and go through with the fine-toothed comb.-- galukalock, Jun 04 2006 random, halfbakery
