I used to watch all his bleach fail videos, but they became repetitive. There’s only so many ways you can ruin your hair with bleach and I think he ran out of ‘oh my god her hair is actually falling out’ ones because most of the later ones I saw were just girls who’d turned their hair a bit orange.
I saw a reddit post asking if he was actually a hairdresser too, because no one could find any proof of him having a licence. I think it was inconclusive as to what his background actually was. He appears to know what he’s talking about at the very least.
