Hair growth

Lovemylife • Mom to two awesome girls. 1 MC. Had my rainbow baby boy 6/5/2017!!!! So in love 😍
Has anyone else turned 30 and hair growth just stopped? I love long hair. I usually grow my hair down my back n then cut it shoulder length n grow it again. But I cut it 5 months ago and it hasn't grown a centimeter. I turned 30 like 6-7 months ago. Is this bc I'm getting older or is something wrong with me that my hair won't grow?
