saguaro-like kanji, horn-shaped locks of hair, young, tender
丱 is a rare kanji with no clear standalone meaning in modern use. The given glosses suggest a visual resemblance to a saguaro cactus and an association with horn-shaped locks of hair, possibly linked to youth or tenderness, but its exact conceptual center is uncertain.
The historical origin of 丱 is uncertain. It may be a pictograph of horn-shaped hair locks or a stylized representation of a plant like a saguaro, but no well-established etymology exists.
The shape resembles two horn-like tufts of hair on a young child's head, or a small saguaro cactus with arms raised. Picture a tender young plant or a child with twin topknots.
For カン, imagine a can of hair gel used to shape the horn-like locks: can -> カン, and the gel keeps the young child's hair in place.
