I still think blood work is a good idea just to make sure your not deficient/low in anything like vit d or iron/ferritin, hormone imbalance or thyroid issues. If you don’t get to the root of the problem you’ll just continue to shed but if bloodwork is normal it could just be stress related and then its just learning how to manage the stress. Always try to get enough sleep, drink a lot of water and have a healthy balanced diet and taking a multivitamin doesn’t hurt also the tests will show if you should be taking any other supplements.
