$0 - my wife cuts my hair. If I were to go to a barber shop, it would be about $10 here in New Orleans.
Its real cheap in India ... Dry hair cut only starting with IRs.10/- ($0.25) to IRs.40/- ($1) in bigger cities ... and more for special treatment that guys goes for sometimes but must be at most IRs.500/- ($13-$14) or slight more.
I pay $15 including tip, its a local barbershop so thats why i pay more I like supporting the small local businesses especially for something I hardly do
I had a Canadian guest staying in my home, he went to get a haircut and paid the man 1$ instead of 0.50$ saying its so cheap here I pay 30$ in canada
