US President Donald Trump made a rare public comment on his enigmatic straw mane Friday, jokingly admitting that he suffers from male-pattern hair loss—a bald spot, reports NDTV.

‘I try like hell to hide that bald spot folks, I work hard,’ Trump quipped during a speech to conservatives just outside Washington, in an unusual flash of self-deprecating humor.

‘It doesn’t look bad, hey, we’re hanging in,’ he added, giving a swirl to the cheering audience.

Trump’s elaborate combing regimen has long been the butt of jokes and speculation.

A tell-all book about Trump’s White House claimed his daughter Ivanka was in the habit of describing the mechanics of the combover to friends:

‘An absolutely clean pate—a contained island after scalp-reduction surgery—surrounded by a furry circle of hair around the sides and front, from which all ends are drawn up to meet in the center and then swept back and secured by a stiffening spray.’
