my battle with moldy closets and frizzy hair

Funny you mention weatherstripping - I've seen that tiny fix make a world of difference, especially in older homes where doors never quite fit right. That said, I’d just add one thing: sometimes the real culprit is airflow, or lack thereof. I once had a client with stubborn closet mold, and after all the caulking and sealing, it turned out their HVAC vent was blocked. A quick vent cleaning and leaving the door cracked now and then did more than any sealant could.

Just double-check you’re not sealing in moisture that’s already there - sometimes you gotta air things out first.

Couldn’t agree more. Trapping damp air just gives mold a cozy home. Sometimes less is more when it comes to “fixing” those leaks.

I get where you’re coming from about airflow, but I’ve actually seen the opposite in a few of my properties. Sometimes, too much airflow - especially in older homes with drafty doors - can actually bring in more humidity from outside, making the closet situation worse. It’s a bit of a balancing act.

Just double-check you’re not sealing in moisture that’s already there - sometimes you gotta air things out first.

That’s key, but I’d add: before you start leaving doors cracked or vents wide open, check what the outside humidity is doing. In some climates, “airing out” just means more damp air sneaks in and feeds the mold. I’ve had better luck with small dehumidifiers in closets, especially in the summer. Not saying sealing is always the answer, but sometimes controlling the air you let in is just as important as letting it out.

Funny how something as simple as a closet door can turn into a science experiment...

Funny how we all end up playing scientist with our closets, right? I totally get the point about outside humidity sneaking in - seen that in a few bungalows where the “fresh air” just made things worse. But have you ever tried passive venting, like those little louvered vents up high on the closet door? Sometimes they let just enough air circulate without bringing in a flood of muggy air. I’m always torn between sealing things up tight and letting them breathe a bit... seems like every house has its own personality. Ever notice how some closets just stay dry no matter what, while others are like mini rainforests? Just makes me wonder if there’s something deeper in the construction or insulation that we’re missing.

Honestly, I think you’re onto something with that. In my place (built in the 1920s), the closets on the north side are always musty, no matter what tricks I try - while the ones facing south stay bone dry. I’ve tried those louvered vents and they help a bit, but it feels like the real culprit is how the walls are built and where the airflow gets trapped. Ever checked for cold spots behind your closet walls? Sometimes there’s just no insulation back there, and it turns into a condensation magnet. Makes me wonder if all the venting in the world can’t fix bad original construction...

Yeah, I’ve noticed the same thing in my house - closets on the outside wall get that damp funk, but the ones in the middle of the house are fine. I pulled off some drywall once and found zero insulation, just cold brick. No wonder it’s always musty. Tried a dehumidifier for a bit, but it barely made a dent. Sometimes I think you just can’t win with old construction... unless you’re ready to rip everything open.

- Been there with old brick walls - had a rental where the closets were always musty, no matter what I tried.
- Ended up adding rigid foam insulation and a vapor barrier when I renovated. Not cheap, but it finally solved the problem.
- Dehumidifiers help a bit, but if the cold wall’s sweating, it’s just a band-aid.
- Sometimes I think these old houses are just determined to keep their quirks... but there’s usually a fix if you’re willing to dig in.

I hear you on the dehumidifiers, but I’ve actually had decent luck combining them with better airflow. In one old basement closet, just adding a vent and running a small fan made a surprising difference. Sure, insulation is the gold standard, but sometimes you can get away with a few strategic tweaks if a full reno isn’t in the cards. Old houses definitely keep us on our toes...

That lines up with my experience - airflow is underrated. I’ve also had luck with moisture-resistant paint on the inside walls. Not a cure-all, but it slows things down if you can’t insulate right away. Old houses really do have their quirks...

airflow is underrated

Totally agree, but I’ll admit I was skeptical at first. For me, it went: 1) pull everything out, 2) scrub with vinegar, 3) slap on that moisture-resistant paint (which, yeah, helps but doesn’t solve it), and then 4) prop the closet door open with a shoe. Not glamorous, but it’s kept my sweaters from smelling like a swamp. Old houses = endless surprises... and frizzy hair days.

Not sure I buy the whole “just prop the door open” fix. I tried that for months - didn’t do much except make the hallway look messy and let my cat nap in my shoes. Honestly, a cheap stick-on vent or even drilling a couple holes up high made more difference than any paint or vinegar. Airflow’s good, but sometimes you gotta give it a little help, especially if you’re not running a dehumidifier 24/7 (which, let’s be real, who wants that electric bill?).

Totally get where you’re coming from. I tried the “door open” trick too - just ended up with dust bunnies and my dog thinking the closet was his new den. The stick-on vent thing worked way better for me, especially after I realized my closet was basically a sauna for sweaters. Paint and vinegar felt like putting a bandaid on a leaky pipe. Sometimes you just gotta let the house breathe a little more, even if it means busting out the drill.

Funny you mention the “door open” trick - I did that for a while and just ended up with my cat nesting in my shoes. Never thought about how much air flow matters until I moved into this older house. Tried baking soda, tried vinegar, even tried those charcoal bags. Nothing really stuck until I put in a vent up top. It’s wild how much of a difference just a couple holes can make. Sometimes I wonder if all the fancy “mold-proof” paints are just marketing, honestly. Letting things breathe seems to be the real fix, at least for me.

- Totally get that. In older homes, airflow is usually the biggest game changer.
- I’ve seen “mold-proof” paint help only when the source issue’s already fixed… otherwise, it’s just covering up problems.
- Curious - how’s your humidity overall? Sometimes it’s not just airflow but what’s coming in from outside or below (crawlspaces, basements).
- Ever try a small fan or dehumidifier in there? Sometimes those work better than any paint or powder.

Totally agree with this. I’ve worked on plenty of places where folks tried every “miracle” paint out there, and the mold just came right back because the closet was basically a sauna. Sometimes it’s as simple as a cracked window or a vent that needs cleaning. Have you noticed if it’s worse after rain or in certain seasons? That can be a clue, too. Mold’s stubborn, but you’re definitely not alone in this fight.

Moldy closets and frizzy hair - honestly, that’s the story of half my clients in humid climates. I’ve seen people shell out for every “anti-mold” paint on the shelf, but if the closet’s holding onto moisture, it’s like putting a band-aid on a leaky pipe. One time, I had a client who swore by these little moisture absorber tubs, but she kept forgetting to swap them out... so the closet just smelled like musty lavender.

I’ve found that sometimes it’s about airflow more than anything. Even just leaving the closet door cracked open a bit helps. And yeah, rain season? That’s when things get wild - closets, hair, everything. I do wonder if anyone’s ever invented a dehumidifier that also tames frizz, because I’d buy that in a heartbeat.

Anyway, I’m with you - miracle paints are great marketing, but they’re not magic. Sometimes it’s the boring stuff (like cleaning vents or fixing seals) that actually works.

if the closet’s holding onto moisture, it’s like putting a band-aid on a leaky pipe.

That’s exactly it. I’ve seen folks spend a fortune on “miracle” coatings and sprays, but if the humidity’s trapped, mold just finds a way. Here’s what I’ve found actually helps, especially if you want to keep things eco-friendly and low-maintenance:

- Airflow is king. Even just propping the closet door open with a shoe or hanger makes a difference. If you can, install a small vent or louvered door - doesn’t have to be fancy.
- Skip the chemical deodorizers. They just mask the smell and sometimes make it worse. I use baking soda in an open jar on the closet floor. Cheap and it works.
- If you’re up for a small project, check for gaps around windows or exterior walls near the closet. Sealing those up with weatherstripping or caulk can cut down on moisture sneaking in.
- For renters or anyone who can’t do major changes, those plug-in mini dehumidifiers are surprisingly effective. Not perfect, but better than nothing.
- As for frizzy hair... I wish there was a magic fix that didn’t involve half a dozen products. I’ve heard some people swear by silk pillowcases or microfiber towels, but honestly, humidity just wins some days.

One thing I’ll mildly disagree on: anti-mold paints aren’t totally useless, but they’re more of a backup than a solution. If you’ve already got airflow and moisture under control, then they help keep things clean longer.

Rainy season is always wild. I had a client who hung cedar planks in her closet - smelled great and seemed to help with both bugs and mustiness. Not sure it did much for her hair though...

It’s always the boring fixes that work best. Not glamorous, but at least you don’t have to keep buying new “miracle” products every month.

Funny you mention cedar planks - I tried that after a neighbor swore by it, and while my closet smelled like a fancy sauna, I can’t say it did much for the actual dampness. What finally made a difference for me was cutting a vent into the closet door. Not the prettiest solution, but once I stopped caring about aesthetics and focused on airflow, the mustiness faded out within a week or two.

I’ve also noticed that those little moisture absorber tubs (the ones with the crystals) work decently if you swap them out often enough. Not as green as baking soda, but less hassle than running a dehumidifier all the time. Anyone else ever try just leaving the light on in the closet for a few hours each day? I read somewhere that heat helps, but honestly, it just made my electric bill sad.

As for hair - humidity’s got a mind of its own. I keep threatening to shave my head every July... never do, but it’s tempting.

Cutting a vent is such a practical move. I used to be so hung up on keeping everything “designer perfect,” but after my own run-in with a closet that smelled like a wet dog, I caved and put in a louvered door. Not exactly a showstopper, but wow, the difference in airflow was immediate. I did try those moisture absorber tubs too - my only gripe is remembering to swap them out before they turn into little science experiments.

Leaving the light on never did much for me either, except making my sweaters feel weirdly warm. I once tried putting a tiny fan in there on a timer, and that actually helped more than I expected. Not the prettiest solution, but sometimes you just have to pick function over form.

And the hair thing... humidity just laughs at any product I use. I’ve given up trying to fight it - now I just call it “beachy texture” and pretend it’s intentional.

Not exactly a showstopper, but wow, the difference in airflow was immediate.

Funny how much of a game changer just a little airflow can be. I’ve always wondered - did you notice any dust issues after switching to the louvered door? I swapped mine out last year and suddenly had to vacuum my shoes way more often. Worth it for the dry closet, but still kind of annoying. Also, did you ever try one of those rechargeable dehumidifiers? I’m curious if they’re actually less hassle than the tubs.

Honestly, I’d take a little extra dust over that musty smell any day, but I get what you mean. The dust situation is real. I actually tried one of those rechargeable dehumidifiers and, to be honest, I found them more hassle than the tubs. They’re always running out of juice at the worst time, and I swear the tubs just quietly do their job. Maybe it’s just me, but sometimes low-tech wins.
