A breakfast ritual with no recorded explanation
The striking part of the story is not just the petroleum jelly, but how little survives about its purpose. The account describes Coolidge’s scalp being rubbed with Vaseline while he ate in bed, yet gives no reason for the treatment. Without a contemporary explanation, it is not possible to tell whether it was grooming, skin care, or something else.
What the ointment could—and could not—do
Petroleum jelly forms a greasy coating on the skin. That makes it useful for reducing moisture loss and protecting dry or irritated areas, but it does not explain why someone would apply it to Coolidge’s scalp. The material itself offers no reliable clue to the intended purpose.
That gap matters: a vivid detail can invite a confident story, but the surviving anecdote supports only the unusual routine, not a diagnosis or a theory about Coolidge’s appearance. The memorable image is simply a president eating breakfast while someone massaged a thick ointment into his hair.
