Ripped off his nail/ripped his nail off

Hi there,

To say that he ripped his nail off his toe, would it be "Se arrancó la uña¨ or ¨Le arrancó la uña"

Can someone explain why it is either way? I asked a native speaker and she told me it was se arrancó la uña, but also that le arrancó la uña somewhat made sense even though it wasn´t ideal. However she really couldn´t explain why.

​

Thank you so much!!
