I think it's more that fixing teeth is largely about replicating a specific material with one-off procedures, whereas fixing hair is all about controlling a complex never-ending process that is linked to all sorts of factors. Also, everyone has teeth issues, whereas hair issues are mostly limited to a subsection of the population (older males, and not even all of them). |

Those men will pay lot of money to get back their hair though.
If I not mistaken it was Bill Gates who said more money is spent in hair regrowth research compared to vaccine to prevent diseases like malaria which kills thousand of people.
