I think nobody talks enough about how each of the sannin all have such glorious hair. all three of them have such long and luscious hair. i bet they traded hair routines and created their own hair formulas. I mean a jutsu like jiraiya's surely requires special shampoo. and just look at how shiny oro's hair is, it wouldn't be out of place in a pantene commercial. and tsunade, as vain as she is, most definitely has a whole ass routine too. hell, looking at hashirama's hair, I bet there's a secret senju haircare routine, passed down through generations. that's their real kekkei genkai. the legendary sannin, more like the legendary luscious locks.
