Hair falling out again??

Brittany

So I lost a decent amount of hair when my little one was around 3 months and it continued to fall out until 6 months. Now, my little guy is one and I have weaned him off breastfeeding it's seems my hair is falling out again... not as much as before but it's still alarming because I already lost so much it's finally starting to make some growth progress. I have tried to look this up online but I can't find anything helpful aside from potential thyroid issues. Has this happened to anyone else?

Thanks!
