why does hair fall happen - #22821

Raghav

I am really worried about my hair lately! Last year, I started noticing that every time I brushed my hair, there was more and more on the brush. My friends say that shedding is normal, but I can’t shake this feeling something's off. I mean, I wasn't stressing and my diet seemed okay; I eat a lot of fruits and veggies! But then I read online about all these reasons, and that got me thinking, why does hair fall happen in the first place? Then, a few months ago, my scalp started feeling kinda itchy, and I thought maybe I was washing it too often. I tried switching shampoos but nothing seems to help. I went to a dermatologist, and they said it might be genetics, but I don't know... my family doesn’t have a history of thinning hair like this. I even did a blood test just to rule out any deficiencies, but everything came back normal! I hear people talk about hormones being a big factor too — is that really true? Why does hair fall happen? Can anyone share their experiences or insights? Do you think I should just accept this as a part of aging or look harder for answers? It’s so frustrating!

Hair loss or “shedding” is a common concern, but it’s great you’re being proactive. Hair fall can have numerous causes, often reflecting both internal and external factors. You’re right, shedding a moderate amount of hair daily is normal, but when you notice more than usual, it’s worth investigating. Hormonal changes, particularly involving androgens like dihydrotestosterone (DHT), can play a significant role, especially in genetic hair loss patterns like androgenic alopecia. Despite no family history, variations in genetic predisposition can start unexpectedly in yourself. Stress, even if not apparent, affects hormone levels and can contribute to hair loss known as telogen effluvium, where more hairs enter a resting phase. Diet, though seemingly healthy with fruits and veggies, could be lacking in certain essential nutrients like iron, biotin, or zinc, and sometimes deficiencies don’t show drastic levels in usual blood tests. Your itchy scalp could suggest an underlying condition like seborrheic dermatitis or even contact dermatitis from your shampoo. It’s beneficial to explore this further with a dermatologist, as they can offer targeted treatments. Ensure your chosen shampoos are mild and suitable for your scalp type. Sometimes antifungal shampoos help if there’s a fungal component to your scalp issues. You mentioned washing frequency; balance is key, as overwashing can strip natural oils. Hair thinning as a part of aging typically doesn’t present with itchiness, suggesting something more than just aging. Tracking any new products or stress and observing over time might give more insight. If unresolved, consider consulting with a dermatologist or trichologist who specializes in scalp health and hair disorders. They might offer treatments like minoxidil or low-level laser therapy, depending on causes identified. Keep track of your symptoms and progress, it’s essential to take an active role in managing your health.
