Isabel Laxamana, from Tacoma, Washington, US, died in hospital on Friday May 29.
King County Medical Examiners’ office ruled the death as suicide.
Days before, a 15-second video emerged online of Isabel standing in a room with some of her hair on the floor.
Her father says: ‘The consequences of getting messed up, man, you lost all that beautiful hair, was it worth it?’
‘No,’ she responds quietly.
‘How many times did I warn you?’ he asks.
‘A lot,’ she replies.
It has been widely reported that the video was uploaded to YouTube by her dad as a way of shaming her for her actions, which are unknown.
A has now been launched called ‘Justice for Isabel’. The description explains it wants to raise awareness of ‘parent shaming’.
