Olivia Munn explained how her five-month romance with ex-boyfriend Chris Pine in 2009 first triggered her trichotillomania, which caused her to constantly pull out her eyelashes.

Olivia Munn discussed her condition, trichotillomania, during an appearance on the 'Armchair Expert' podcast. Munn said that it was while she was dating Chris Pine that the comments on a paparazzi photo of her initially triggered the disorder.

The Your Friends & Neighbors star has been candid about the hair-pulling disorder, which the actress said typically manifests in her picking out her eyelashes. She told Dax Shepard about the first time she started hair pulling on the most recent episode of the Armchair Expert With Dax Shepard podcast.
