If you’ve noticed more strands in your brush or clogging your shower drain lately, you might be thinking if it’s due to genetics, but no, it’s not always about genetics. While hereditary hair loss does play a big role for many people, it’s not the only factor. Every day habits, from the food you eat to how you manage stress, can have a big impact on your hair’s health.
But relax… these lifestyle-related causes of hair loss are often reversible. Let's take a closer look at how certain habits might be affecting your hair and what you can do about it.
How Lifestyle Affects Your Hair
Hair loss doesn’t always happen overnight. It’s often the result of small things adding up over time, like skipping meals, smoking, running on little sleep, or even styling your hair too tightly. These choices can weaken your hair at the root, making it more prone to shedding or breakage.
Unlike genetic hair loss, which is more permanent, lifestyle-related hair thinning is often temporary. And the even better news? With a few smart changes, you can often get things back on track.
Your Diet Matters More Than You Think
Are You Eating Enough (of the Right Things)?
What you put on your plate shows up in your hair. If your meals are missing key nutrients like iron, zinc, protein, or healthy fats, your hair may not get what it needs to grow strong. One common issue is low iron, especially in women. It’s one of the most overlooked causes of hair loss. Without enough iron, your body prioritizes vital functions over things like hair growth. Crash diets or overly restrictive eating habits can also do a number on your hair. If you’re suddenly cutting calories or food groups, you might be missing out on the building blocks your hair needs.
Try this instead: Include a mix of leafy greens, lean proteins, nuts, seeds, and healthy oils. These foods nourish your scalp and strengthen your hair from within.
Stress and Hair Loss: A Real Connection
When Life Feels Heavy, Your Hair Can Pay the Price
We all go through stressful times, but chronic stress? That’s when it can start to affect your body in more visible ways, including your hair.
Stress can push more hair follicles into what’s called the “resting phase,” meaning they stop growing and eventually fall out. You might not notice it right away, but a few months later, you could see increased shedding, especially after brushing or washing your hair.
Smoking and Hair Health: What’s the Link?
Yes, Smoking Can Lead to Hair Loss
You already know smoking affects your lungs and heart, but it can also take a toll on your hair. Nicotine and other chemicals in cigarettes reduce blood flow to the scalp. Less blood flow means fewer nutrients and less oxygen reaching your hair follicles, which can weaken them over time.
Plus, smoking speeds up aging, which includes the premature graying and thinning of your hair. If you’ve been thinking about quitting, your hair is just one more reason to make the change.
Are Your Hair Habits Hurting Your Hair?
A Few Styling Mistakes Can Add Up
It’s easy to overlook how much our daily hair routines affect our strands. But repeated heat styling, tight hairstyles, or even brushing your hair the wrong way can cause stress to your scalp and hair follicles.
Some common culprits:
-
Using high heat from flat irons or blow dryers too often
-
Wearing tight ponytails, braids, or buns regularly
-
Over-washing or using harsh shampoos
-
Applying chemical treatments like dyes and relaxers without giving your hair a break
Treat your hair gently, especially when it’s wet, as that’s when it’s most fragile. Opt for loose styles, use a wide-tooth comb, and give your scalp some TLC with gentle massages or scalp oils.
Other Habits That May Be Affecting Your Hair
It’s Not Just What You Eat or How You Style
There are a few more lifestyle factors that may surprise you:
-
Poor sleep: Not getting enough rest can throw off your hormones, which may interfere with your hair’s growth cycle.
-
Dehydration: Your hair needs moisture to stay strong. If you’re not drinking enough water, your strands may become brittle and more prone to breakage.
-
Too much alcohol: Drinking in excess can deplete your body of important vitamins, which directly affects your hair health.
What You Can Do About It
Making small but consistent changes can lead to big improvements in the way your hair looks and feels. Here's where to start:
-
Eat a nutrient-rich diet: Focus on iron, protein, healthy fats, and vitamins like D and B12.
-
Manage your stress: Incorporate calming habits like meditation, regular walks, or breathing exercises.
-
Rethink your hair care routine: Avoid excessive heat, limit chemical treatments, and be gentle with your hair.
-
Stay hydrated and sleep well: These two often-overlooked habits can help reset your body and support hair regrowth.
-
If you smoke, consider quitting: It’s tough, but the benefits for your hair (and the rest of your body) are worth it.
When to See a Doctor
If you’ve made lifestyle changes and still notice ongoing hair loss, it might be time to check in with a healthcare provider. Sometimes hair thinning is linked to underlying issues like thyroid problems, hormonal imbalances, or autoimmune conditions.
Your doctor can run tests, suggest treatments, or recommend supplements that can help you get to the root of the issue… literally.
Conclusion
Hair loss can feel frustrating, but it’s often your body’s way of asking for support. Many of the habits that affect your hair also impact your overall health. So when you take steps to eat better, manage stress, and take care of your scalp, you’re not just doing it for your hair, you’re investing in your whole wellbeing.
