Why You Shouldn’t Blow-Dry Your Hair with the Door Closed
Wash day is already a process.
You’re deep-conditioning, detangling, styling — and probably just trying to get through it as efficiently as possible. But there’s something you probably haven’t considered during all of this: your air quality.
Let me show you why that matters.
I Tested My Air While Blow-Drying My Hair
I used an air monitor — not the kind that identifies every chemical, but one that shows how many small particles are floating around in the air. These are known as PM2.5 (more on that in a second).
When I started blow-drying my hair with the door closed, the air quality number began to climb. By the time I was finished, the number had maxed out the monitor.
Like, it couldn’t even measure any higher. The particle buildup in the room was that intense.
And all I did to bring that number down? Opened the door. Just that simple act cut the level of particles in the air in half.
What’s Actually in the Air?
Let’s talk about PM2.5. These are tiny particles — smaller than the width of a human hair — that can get deep into your lungs and even enter your bloodstream.
They’re linked to:
Respiratory issues
Hormonal imbalances
Fertility problems
Fibroids
Cardiovascular disease
And long-term chronic health risks
You might be wondering: What does this have to do with hair?
Well, between the heat from styling tools, products we’re using, and the lack of ventilation in small spaces (like bathrooms), we’re creating a cloud of particles and vapors we then breathe in — often without realizing it.
Why This Matters for Black Women
We’re already spending more time and using more products on our hair — not always by choice, but because of texture, styling expectations, and cultural norms. That means we’re more likely to be exposed to these air quality issues regularly — and disproportionately.
And in communities already dealing with environmental health disparities, this adds another layer to the conversation about beauty justice and health.
So What Can You Do?
This isn’t about shame — it’s about awareness. And small changes can make a real difference:
Open a window or door while styling
Use a fan or air purifier to keep air moving
Take breaks between product application and heat styling
Check out your own air quality with a monitor (optional but eye-opening)
The goal is simple: reduce what you’re breathing in during your regular routine.
Final Thoughts
Have you ever thought about your indoor air quality? Especially during something as routine as doing your hair?
It’s easy to overlook — but those small particles add up. And taking steps to improve your air doesn’t have to be complicated.
