I noticed that after a stressful period at work, my hair started shedding noticeably more. My friends say it's because of stress, but I don't understand the mechanism - how exactly does nervous tension affect hair follicles, and is there any way to stop it?
Stress triggers a whole chain of hormonal changes in your body 😟 When you're stressed, your adrenal glands release cortisol, which is your "fight or flight" hormone. An increase in cortisol can shift hair follicles from the growth phase into the resting and shedding phase - this is called telogen effluvium. Plus, stress narrows blood vessels, which reduces blood flow to the scalp, so your hair doesn't get enough nutrients. At the same time, your immune system can go haywire and start attacking hair follicles. In short, the mechanism is complex, and it's hard to pinpoint which of these factors is the main one in your specific case.
To stop the process, you need to work on two fronts: reduce the stress itself and support your hair. Start with the obvious stuff - try to get enough sleep, move around, go for walks, maybe meditate or just find time for your hobbies 🤳 Stress management really does help. And at the same time, make sure your hair is getting enough iron, zinc, and protein - often when people are under chronic stress, they eat poorly, and their hair doesn't get the building blocks it needs.
If your hair was shedding heavily for a couple of months but you've already gotten through the worst of it, things often normalize on their own - it just takes time. If the shedding continues for months or you've noticed bald patches, it's worth seeing a dermatologist to rule out other causes and get recommendations on vitamins or treatments if needed.
After going through a difficult period in my life, I noticed my hair was literally falling out in clumps - I'd comb out huge strands, and then it would take a month or two to recover. Turns out, it's called telogen effluvium: stress throws off your hair growth cycle, and the follicles prematurely enter a resting phase, which causes the hair to basically die off and shed.
The main thing to understand is that it doesn't last forever. Once your mental state stabilizes, the cycle restores itself on its own, though it might take a few months. Anything that reduces stress helps: walks, proper sleep, maybe some kind of relaxation practice. But miracle shampoos won't do it - you need to actually deal with the stress itself, not just the symptom.
The key thing to understand is that hair doesn't fall out instantly - it usually happens with a delay of several weeks or even months after a stressful period, so people often don't connect the cause to the effect. To stop the hair loss, you need to first and foremost reduce your stress levels: normalize your sleep, add physical activity, and meditation or just regular walks can help. If your hair is falling out very intensely and it clearly isn't from recent stress, it's worth getting your blood work checked - sometimes hair loss signals an iron deficiency or other micronutrient shortages that get depleted during prolonged stress.
Hair reacts to stress through the hormonal system, but the mechanism is a bit more complex than just a cortisol surge. When you're constantly under tension, your body redirects resources to "critical" functions - heart rate, breathing, muscles. Hair follicles shift from the growth phase into a resting phase, and then into a shedding phase. This is called telogen effluvium, and it can continue even after the stress ends - which is why hair often starts falling out with a delay, weeks or months later.
The key thing here is that this is usually a reversible process if the stress isn't chronic. If the pressure's gone and you've given yourself time to rest, your hair should recover on its own eventually. But there's a catch: if you start obsessing over the hair loss and getting anxious about it, the stress continues, and the cycle closes. You end up in a vicious circle where worrying about your hair prevents it from recovering.
What actually helps is reducing overall tension. Sleep, physical activity, trying to take your mind off problems for a while. If you can, break big tasks into smaller chunks so you don't feel so much pressure all at once. If the shedding is severe or lasts for months - it's worth seeing a dermatologist, because there could be multiple causes at play (iron deficiency, vitamin deficiencies, thyroid issues).
