While in New York City on Wednesday night — sans her hair being done — fans couldn’t help but notice Perry’s damaged hair.
“It looks like she’s totally balding and losing her hair,” one eyewitness told Radar.
“There were thinning patches all over and it’s pretty obvious all the hair treatments and extensions and stuff has really beat up her hair.”
“Katy’s hair looked terrible, to be honest,” the source said.
“It’s amazing what’s really left under all the glitz and glam once the wigs are off.”
Perry, 29, is known for her outrageous and colorful hair, whether it’s a big red wig or coloring her hair blue — all of which could attribute to her hair loss.
“You can really see some hair loss by her temples,” another source added.
“It’s extremely noticeable, and shocking, in person.”
