“the human inner ear does have some (limited) natural hair cell regeneration capabilities”

I read this on Tinnitustalk (https://www.tinnitustalk.com/threads/stanford-initiative-to-cure-hearing-loss-now-lists-tinnitus.12914/#post-600032)
It’s quoted from a video of Stanford initiative discussion.

I thought hair cells don’t regenerate at all? Do you guys think it’s possible that hair cells regenerate if they are not exposed to further trauma?
