My hair needs help

Jaz

I’m 6 months post partum. I have just started to lose some hair, but my issue is my hair looks horrible. I’m wanting to grow it out for my wedding. I just had a hair cut a month and a half ago. Is this new hair growth making it crazy or something else?! Any tips would be nice?! And how to grow hair (no supplements, I’m breastfeeding) ?!
