Fleas in hair. washed multiple times and theyre still there. i have been bitten endlessly. what do i do?

You must treat your pets first/also. Be certain it is not lice. Get pictures for us to see when you do a video consult.

Are you sure they are fleas and not head lice? Lice are not killed or removed by standard shampoos; you need a medicated shampoo. Best to see a doctor to confirm the diagnosis and then follow his or her treatment advice. Or look for an over-the-counter anti-lice shampoo, like one with active ingredient permethrin (e.g. RID®, NIX® and others), but for sure see a doctor if that doesn't work.
