That's the most common response I receive but I don't think it holds true in my case. For example my current girlfriend was extremely surprised when I told her I didn't use soap or anything about 6 months into our relationship. Same sort of surprise amongst my housemates since I am pretty hygienic and well-groomed.
I probably use soap on my body 3 or 4 times a year (still wash hands regularly), and shampoo once a week and notice no difference from how I smell from when I am using both.
In terms of hair-greasiness, when I began my hair was much longer and did feel greasier and appear more out of order, but with shorter hair there is not much of an issue and the shampoo once a week can stave it off.
Anyways, it seems like he is greatly exaggerating how badly he smelled. I smell no different, granted I apply deodorant to my underarms once a day but probably would not have to. Nobody I know comments on any bad smells either.
