If your hair is falling out in clumps resulting in bald patches, perhaps you have alopecia? Might be worth a visit to a dermatologist to determine. If it's generalized, diffuse hair loss, telegen effluvium, that can be brought on by stress and usually resolves. It it's alopecia, that's an autoimmune disorder resulting in small round patches of loss (alopecia areata) or total baldness (alopecia totalis). Hair loss after Covid is quite common. A dermatologist will be able to diagnose and will hopefully order bloodwork to see if your thyroid is functioning properly as hypothyroidism can cause hair loss. They might also check iron/ferritin levels. You might consider working on stress reduction (almost impossible when you are losing your hair. I know from experience!) and also making sure you are getting proper daily nutrition. Adequate protein is really important as well. I was diagnosed almost 20 years ago with alopecia and it was my hairdresser that discovered it as well! I treated it medically for many years which was a mistake but the only option at the time as there wasn't a dietary understanding and integrative approach that I could find. Many years later information became available on the association of gluten and autoimmunity. I ended up eliminating gluten and dairy entirely and the condition mostly resolved. If it ends up being alopecia, feel free to message me if you want to discuss.
