Birth Control ?

I got the birth control shot in August, I had irregular bleeding for almost 2 months! Well. . . After the bleeding stopped my hair started to fall out really bad, and I'm literally going bald (again)

Has anyone else experienced this while on the shot? What did you girls do? Is there any products you recommend to help me grow my hair back or make it stop falling out?

Thank you in advance loves! ❤❤❤
