Regrowing hair will be the last thing every solved.
- ben_w 5y agoNah, too much money in that. Last will be something with little obvious outward sign, and I’d guess brain related. Open question [ELI15]: why can’t we tissue culture scalp skin for hair, like we can skin in general for treating burns victims?
- eric__cartman 5y agoI don't think it'll be brain related. After all there's no use in have a healthy body at an old age if the patient is suffering from degenerative illnesses that affect the brain.
- ben_w 5y agoIndeed, but I think brains are harder to test than anything else.
- jelliclesfarm 5y agoI would bet on teeth. Dental services are the biggest money makers. ETA: question.. why aren’t we able to regrow teeth and enamel? Imagine..if we can reverse cavities and no more root canals ever?

- gnitz 5y agoGum regrowth could also be an enormous money maker since most adults have gum disease to some degree and it worsens with age. The cells are skin-like and delivery could even be through some sort of brushable paste.
