The informant learned from his father, who learned from his mother, not to comb your hair when wet, as doing so would make you more susceptible to being struck and killed by lightning.
This belief is likely rooted in the observation of static electricity, a phenomenon which immediately evokes images of lightning.
The informant’s grandmother, who received no formal education, was born, lived, and died in Irapuarto, Mexico. The informant is generally mistrusting of all things he has learned from his grandmother, as he refers to most folk belief as “batshit.” Such beliefs hold no weight to him and serve only to be laughed at.
