How does animal testing really work?

I was thinking about it and realized that I’ve got a lot of preconceptions from my teen vegan years (Yeah, I used to be that guy). I still think we’re unnecessarily cruel to animals in many ways but definitely no longer trust PETA as a reliable source. So, does the US government really require new shampoo products to be poured over cute bunnies’ eyes before entering the market or is that just BS? Can anyone enlighten me on when and why animal testing is necessary leaving the moral discussion aside?

Thanks in advance.

Edit: Thanks for the responses, guys! I’m all for medical testing, which I understand covers the vast majority of animal experiments. I’m still against cosmetic testing, regardless of how the suffering is minimized, but it was nice to hear from people who work at the labs and learning that they do care about their animals.

Also, for the record, I wouldn’t trust PETA to take care of a plant.

I don’t know the specifics for shampoo. But for animal research, before any experiment you need to write up a proposal that dictates why the animals needs to be tested, and the measures you will take to do it in the safest way possible, using the least number of animals. You also need to show why it is imperative animals need to be used, and the good that will come out of it.

It is Incredibly regulated, and scientists take great care to do it the best way possible. At the end of the day animal testing saves lives by providing necessary medication and vaccines that would not be available without it.
