What is it about Iwasaki hair salons?
I guess you get what you pay for. ¥980 gets you a 50/50 chance of a decent haircut, wholly dependent on the personality of the person who's cutting your hair and her (usually her) opinion of what your head should look like. Which, more often than not, ends up producing a striking resemblance to hers.
I'd like to chalk it up to a language barrier, but even I can communicate "five centimeters", with my thumb and forefinger holding an imaginary tangerine for emphasis. How five becomes twenty, I'm not sure, but the aggravation soon fades to acquiescence as I await my fate.
At least my hair grows fast.
