Pricing: How much does it cost for men's hair cut in different countries?

In Mexico you will find a  men's haircut for less than 5 dollars, up to $50  in an upper class hair salon. Plus tip. In Milan the cheapest will be 20 euros up to 100 euros plus tips.

London is generally an expensive city but I get my haircut at a neighborhood barber shop that costs £5.50 (about $8-9 USD) and it is cheaper than what I used to pay when I was living in the US! In fact, my dog's hair grooming costs about £35-40 each time, which is about 7 times more expensive than my hair (although she probably has 7 times more hair than I do).

Same is the case in Pakistan as in India. You can get a Decent haircut for $1 to $1.5, but you can get even cheaper for cheaper places like on road side for about $0.30 to $0.35.

Stockholm is by far the most expensive place for a hair cut that I have lived in. It costs around 250 to 300 Kronor (€30 to €35) on an average. And these are just the cheap and ordinary saloons. The top ones charge almost twice as that!!

I see that you have mentioned the price in India to be USD 1 to 2. Actually, those prices are for middle class places. There are cheaper places, for 30 cents per haircut. These are basically on the roadsides, and the customers sit on bricks. There are no structures.
