What health issues cause hair loss?

Oh god, hair loss can be so scary, right? I always worry about every little change. But yeah, things like anemia, PCOS in women, severe stress, or even certain medications can cause it. It's best to get it checked so you don't keep overthinking like me!

Beta, don't worry too much. Sometimes it's just age, or after a big illness like fever or surgery, hair falls a bit more. I remember my hair falling after my deliveries. Also, low iron or vitamin D is common. Simple changes can help a lot, but seeing a doctor is always good.

Straight up, the main culprits are often hormonal issues like thyroid, or nutritional deficiencies like iron and Vitamin D. Stress is also a massive factor these days. Don't self-diagnose; get a blood test done and consult a dermatologist.

Bro, my hair was falling like crazy during exam stress! So definitely stress. Also, my friend had really bad hair fall because of low iron. Like, sometimes it's just simple stuff, sometimes it's more serious. A doc visit is the easiest way to figure it out.

Oh, I didn't know so many things could cause hair loss. What about scalp infections? Can those also make hair fall out a lot? I'm trying to understand more.
