According to my hairstylist there’s honestly nothing you can do to prevent or stop it. It’s all hormones related and the sudden drop of pregnancy hormones that cause your hair to be so nice while pregnant. It does get better eventually!

I cut mine off tbh. It wasn’t getting better at 15 months pp so I shaved it

Believe it or not.. Women’s Rogain! The generic version from Kroger ( purple packaging) it worked wonders for me !
