If I ate a very strong edible in June of last year (2019), will I likely fail a hair follicle test?
Also my hair is shoulder length and grows at a slowish rate if that is helpful at all.

Probably not, but if you're worried, just shave your head. They won't find THC if there's no existing hair to find it in.

The test will detect THC for about 3 months after ingestion.
