I think I lost my curls after giving birth!

I’ve always had very curly hair, my hair has always been long and it’s the one trait about me I’ve been known for. I love my curly hair so much, I took so much pride caring for it. My hair was great during pregnancy but now I’m 8 months post partum and I’ve noticed for the longest time now, months, that my curl pattern just isn’t the same anymore. My curls are a lot looser than they were. Not wavy, but definitely a lot looser. I got a hair cut, thinking my hair was just weighed down and needed to be revived but it didn’t necessarily help it look any curlier. I am on the lucky end, in that I didn’t really get postpartum shedding. But as for my curl pattern it’s just so different now and I’m so sad! I’ve tried the same and new products, deep condition, style my hair the way I know. I don’t use heat or dye. So I’m guessing it’s just hormones. I say all this to say, if anyone else has noticed their curl pattern change after giving birth, was it permanent or did it eventually return to normal?
