I dont know if there is a place with exclusively long haired women, but I have been in Bali 3 times, and some surounding islands, and I was in fact with a girl with kneelenght hair! In Bali. I actually posted the whole story here on this forum over a year ago, because it was such a coincidence how I met her! Her hair was tied in a tight bun, I didnt ask about lenght, untill we were in the bedroom, and she let loose her almost 5 foot long hair!! It was legendary.. I will never forget this!!
