is sensorineural hearing loss permanent?

A Guru in his own eyes that have a youtube cannel and call himself "real world audio" claim that you can overcome sensoineural hearing loss by and even his mentor ,Stu, had told him so. And this is by special method that they know.

i was so suprised how many Audiophiles want to believe those mumbo jumbo

so, for all those:

SNHL is usually permanent . Once the hair cells of the inner ear are damageed or lost, they can’t be repaired
