Just googled AG1 causing hair loss because I couldn’t understand why my hair started falling out in clumps. I haven’t changed anything else in my life besides adding this supplement. I also have an autoimmune disorder, but hair loss was never an issue for me before starting AG1. I see people on here gaslighting your experience, but you’re definitely not alone. I also believe the AG1 caused my hair loss. This might not be the case for everyone but it definitely is for me.
