Donald Trump’s hair is sparking fresh online speculation after footage appeared to show a thinner area while he boarded Air Force One, followed days later by appearances where his hair looked noticeably fuller and more voluminous. A medical aesthetician said a wig or hairpiece is one possibility but stressed that images cannot prove it. She also ruled out rapid natural growth or a recent transplant as likely explanations, while pointing to styling, hair fibres, lighting and camera angles as factors that can dramatically change the appearance of hair. Former Republican congressman Adam Kinzinger also weighed in, but his comment remains speculation rather than evidence.
