[Kids Next Door] How did Delightful Children make Nigel permanently bald?
gpt
It was never canonically stated *what* exactly happened, just that the DC made Nigel bald before he joined the KND. 

However, given the kind of world C:KND is, you could probably imagine the Delightful Children did something like "transfer Nigel's hair-growing to a balding adult (Father?) with some advanced helmet device" or "suck out the hair follicles of kids with good hair and turn them into hair growth pills for evil adults" or something along those lines. Probably more like the former, given that perma-baldness might require a special device.
