Might have to consider cutting my hair 😭

Ever since my March baby was about 2 months old, so much of my hair falls out. Especially when I'm washing it.

I've tried different shampoos and conditioners.

I've tried changing my pillows.

I've tried washing it more.

I've tried washing it less.

I've tried different brushes and combs.

I've tried leaving it down.

I've tried having it up.

Nothing is working and I want to cry because it took me forever to get it back to this length after previously cutting it all off. Any advice?
