I’m going to have another meltdown

I’m almost 7 months postpartum and my hair is still shedding like crazy! My hair sheds the most after a shower and I end up having a meltdown in front of the mirror. My hairs so thin and I think I’ve tried most things, I have my vitamins and I have a balanced diet. I currently use Cantu cleansing shampoo as I get a lot of buildup or maybe it’s dandruff?

I use almond oil and sometimes Argan oil I also

I’m East African so I have mixed race hair. Can someone please help me out
