Hair help

Ever since I had my little my scalp has been itching soooooo bad. It doesn’t matter what I use, or don’t use. How often I wash or how many days I wait. On top of it my hair loss has been crazy, I have to clean my brush after ever use and in the shower I get quarter sized balls of hair, not including what makes it down the drain.

I’m a ftm and I don’t know what’s normal, and the hair loss is annoying but I can ignore it, but the scalp itching is awful so I’d like some tips if you would please ☺️
