I really can relate! It’s a very scary and stressful thing. I’ll just say what I have experienced. My shedding was rather sudden. I had beautiful long hair, then it was very thin. Scalp showing thin depending on how I styled it…..I began consulting with my dermatologist. At the time, I was going through a lot. I had a full panel of blood work….from vitamin levels, iron, thyroid, a1c, etc. I was treated for Vitamin b12 deficiency in April. I had also lost a great deal of weight in a short time. Plus, had been diagnosed with post covid syndrome. And, suffered extreme anxiety due to a number of reasons. I’m now seeing a therapist. (Now, I’m much better.)

After all was considered, my endocrinologist (i have type 1 diabetes) and dermatologist concluded that it was telogen effluvium that caused the rapid shedding , due to my rapid weight loss. (Now totaling 65 pounds, 50 of it being lost with hair loss.) They say the post covid syndrome may also be a factor (you can find videos online of covid hair loss), as I also got smell/taste disorder around the same time, i still have those. The good news is that my hair should return. I wasn’t getting enough calories and recently met with a nutritionist and she gave me great advice that I have incorporated into my diet.

Hormones can also cause hair loss, as well as autoimmune disorders…..so many things. A lot of women experience it. I’d consult with a dermatologist without delay. I hope you can find answers. Please post your updates. I know how stressful this can be. I have a prescription for minoxidil, as that is the only real treatment for hair loss, according to my doctors. I may have to take it a year until my hair returns naturally, though I haven’t started yet. . It’s already shedding less, so I may just let it return naturally. The med is topical or pills.
