Lovely Locks

In the last few months, Jman decided to grow his hair long (much to the chagrin of his father). In the past he has had a "high and tight" military style haircut, which was easy to care for, no work at all. With the longer hair we've had to be on his case, reminding him that he actually has to brush his hair now that it is longer than an inch.
When I woke him this morning, I casually tousled his hair and noticed that it felt very oily. So I asked him if he was shampooing his hair or if he was using bar soap to clean it (he's done this in the past). He assured me that he was using the shampoo in his shower. My next question, "are you getting a good lather?", since he sometimes rushes his hair washing. His answer was no. OK. I told him to get out of bed and I would show him how to get a good lather. As we are soaking his head, he mentions that he did not realize he has to WET his hair first. What?!?!? He's been showering with no help for 5 years, has he never washed his hair in this time?
After his shower tonight, I checked his hair again - still not clean. What the heck is going on? Why is his shampoo not lathering? I inspect the bottle (who's label has come off) and notice that it is conditioner. When he last ran out of shampoo, whenever that may have been, he grabbed a bottle of conditioner from my vanity. Luckily, after careful questioning, we determined that it was not that long ago when he did this. We got a new bottle of shampoo out - his hair is squeaky clean now.
