Hair Splitter

On Dealing with Split Ends
  (+2, -1)
(+2, -1)
  [vote for,

Every now and then someone notices that the end of a hair has split. Horrors! For some reason split-ends are socially frowned-upon. Currently the standard way to fix them is to go to the hairdresser and get a trim, or get some special hair goop that basically can glue the split ends back together.

Well, time for a new solution. This one is an extremely sharp diamond blade, with an appropriate holding device. You place the split-end hair in the device, and slide the diamond blade down the length of the hair, thereby giving you two full-length hairs (albeit half as thick), neither of which has a split end!

This Idea is half-baked, of course, because usually someone has a lot of split-end hairs to deal with. I've read that the average non-bald person has about 100,000 hairs on the head. It could take a while to apply this device to each and every split-end hair!

Obsidian http://en.wikipedia.org/wiki/Obsidian
"obsidian blade edges can reach almost molecular thinness ...." [8th of 7, Jul 03 2011]


       The problem is, the hair will grow out, and you'll have to extend the cut down to the follicle, on a regular basis, for each hair. But for those inclined to split hairs, that's not a bug, it's a feature.   

       [mouseposture] Industries, Stg. plans to market a system consisting of: A dissecting microscope, two pairs of jeweler's forceps, a special glue (very low viscosity, so it can be dispensed from a pulled-glass micropipette), and a device for aligning the split ends (the prototype uses a groove scribed on a glass slide).   

       The major problem we're encountering in development is the difficulty convincing our beta testers to take breaks for meals and personal hygiene.   

       [jutta] I hope this doesn't run afoul of the "no advertisements" policy?

       Obsidian might be better than diamond in this application.

       Let's not split hairs over it.

       With respect, [Vernon] may require more than one head of hair to express himself fully.

       It's only a short step from follicular manslaughter to going full-on Sweeney Todd.
Just sayin...

       [8th of 7], with thousands of hairs to split, that's why I chose diamond over obsidian. It will last longer! I'm also fairly sure that diamond can be even sharper than obsidian (the atoms making up the material are smaller).

       I'm told that diamond microtome blades are better than glass ones, and last longer; glass is often used, though, because the diamond ones are so expensive.
