How to Make Brushes Soft Again

Ever picked up your favorite makeup brush only to feel like you're trying to blend with a tiny broom? You're definitely not alone. Over time, even the softest brushes can turn into scratchy tools that make applying makeup feel more like punishment than pampering. The good news? Most "ruined" brushes can easily be saved with the right techniques.
Whether you're dealing with crusty foundation brushes (eww) or powder brushes that feel like they've been through a sandstorm, this guide will help you bring them back to life. We'll walk you through EXACTLY why brushes get stiff in the first place and give you the steps to restore that buttery softness you fell in love with. Plus, we'll share some DIY tricks that might surprise you and help you avoid this in the future...
Why Do Makeup Brushes Get Stiff?
Your brushes didn't just decide to be difficult one day (happens to all of us). There are actually a bunch of reasons why they lose their softness, and understanding these will help you prevent it from happening again. Here's what's REALLY going on with those stubborn bristles.
Buildup of makeup, oils, and dirt
This is the biggest culprit behind stiff brushes. Every time you use a brush, it picks up makeup, natural oils from your skin, and environmental dirt. When you don't clean thoroughly (or skip cleaning altogether), all this stuff builds up layer by layer, basically just gluing the bristles together. Think of it like hairspray buildup in your hair - the more it accumulates, the stiffer and crustier everything becomes. Oil-based products like cream foundations and concealers are especially guilty of this since they're harder to remove with basic cleaning.
Incorrect cleaning methods
Here's where things get tricky. You might think you're doing everything right by washing your brushes regularly, but using the WRONG technique can actually make them stiffer... shocking, right? Scrubbing too hard, using the wrong movements, or not rinsing properly can damage the bristles and leave soap residue behind. That leftover cleanser hardens as it dries, leaving your brushes feeling stiff and weird. It's like washing your hair with shampoo but forgetting to rinse it out properly. Not good.
Using harsh soaps or hot water
Your brushes are more delicate than you think. Using regular hand soap, dish soap, or scalding hot water might seem like it'll get them cleaner, but it's actually destroying the bristles. Hot water can damage both synthetic and natural bristles, while harsh detergents strip away the natural flexibility that keeps them soft. Even some "makeup brush cleansers" are too aggressive if they contain high levels of alcohol or sulfates, which is why we keep our cleansers soft and gentle.
Wear and tear over time
Let's be real... nothing lasts forever, and brushes are no exception. Over months and years of use, bristles naturally start to break down. The cuticles on natural hair wear away, and synthetic fibers can start to fray or lose their flexibility. This is totally normal, but proper care can definitely slow down the process. If you've had your brushes for years and they're getting stiff despite good care, it might just be time to accept that they've lived a good life.
Quick Guide to Restoring Softness
Ready to bring those stiff brushes back to life? This process takes a bit of time and patience, but it's totally worth it when you feel how soft your brushes become and after all, your makeup is just as good as your brushes. Follow these steps in order for the best results.
Step 1 – Deep Clean Your Brushes Properly
Start by removing all that built up gunk that's making your brushes stiff. Gently swirl your brush in a small bowl of lukewarm water mixed with a gentle cleanser (baby shampoo works perfectly here). Don't press hard - let the cleanser do the work. You'll probably see makeup, oils, and dirt coming out in the water. Keep swirling until the water runs clear, which might take a few rounds with fresh water and cleanser. For REALLY stubborn buildup, you can let the brush soak for a few minutes, but never submerge the ferrule (that metal part that holds the bristles) otherwise it's doing more harm than good.
Step 2 – Use Gentle, Brush Safe Cleansers
Not all cleansers are created equal when it comes to brush care. Baby shampoo is actually one of the best options because it's designed to be gentle and won't strip away natural oils. You can also use specialized brush cleansers, but check the ingredients - avoid anything with harsh sulfates, high alcohol content, or strong fragrances. Some people swear by mixing a drop of olive oil with baby shampoo for extra conditioning power. Whatever you choose, make sure it's something you'd be comfortable using on your own hair.
Step 3 – Rinse with Lukewarm Water
Temperature matters more than you think. Hot water can damage bristles and loosen the glue in the ferrule, while cold water won't rinse away the cleanser effectively. Lukewarm water is the sweet spot - warm enough to dissolve residue but gentle enough to protect the brush. Always rinse with the bristles pointing downward to prevent water from getting into the ferrule, which can cause the bristles to shed or the brush to fall apart completely.
Step 4 – Condition the Bristles
This is the step most people skip, but it's crucial for restoring softness. After cleaning, apply a tiny amount of hair conditioner or specialized brush conditioner to the damp bristles. Work it through gently with your fingers, then let it sit for a few minutes. This helps restore flexibility and smoothness, especially for natural hair brushes. Rinse thoroughly afterward - any leftover conditioner will make your brushes feel greasy and attract more dirt.
Step 5 – Dry Them the Right Way
How you dry your brushes can make or break all your hard work. Gently squeeze out excess water with a clean towel (don't pull or tug on the bristles), then reshape the brush head. Lay them flat on a towel with the bristles hanging over the edge of a counter - this allows air to circulate around them and prevents water from seeping into the ferrule. Never stand wet brushes upright in a container, or whatever will go to the handle. Depending on the size and density of your brushes, they should be completely dry within 8-12 hours.
DIY Remedies for Stiff Brushes
Sometimes you need to get creative to save your brushes, especially if they're really far gone. These DIY treatments use ingredients you probably already have at home and can work wonders on stubborn stiffness. Just remember to be gentle and patient.
Olive oil or coconut oil treatment
This sounds weird, but it actually works amazingly well for really stiff brushes. Work a tiny amount of olive oil or melted coconut oil into the bristles and focus on the areas that feel the stiffest. Let it sit for about 10 minutes - the oil will help break down stubborn buildup and restore flexibility to the bristles. Then wash thoroughly with baby shampoo to remove all the oil (this might take 2-3 washes). The key is using just an itsy bitsy bit - too much oil will be impossible to wash out and leave your brushes greasy. And nobody wants that.
Vinegar and baby shampoo soak
Mix equal parts white vinegar and baby shampoo with a little lukewarm water to create a gentle but effective cleaning solution. The vinegar helps dissolve mineral buildup and stubborn residue, while the baby shampoo conditions the bristles. Let your brushes soak in this mixture for 15-20 minutes, then rinse thoroughly. You might smell a bit of vinegar at first, but it disappears once the brushes are completely dry.
Store bought brush conditioners
If DIY isn't your thing, there are some solid commercial options out there. Look for brush conditioners specifically designed for makeup brushes rather than hair products. Some popular brands make conditioning sprays that you can use between deep cleans, while others offer intensive treatment masks for really damaged brushes. These tend to be more expensive than DIY options, but they're formulated specifically for brush bristles and often work faster than homemade treatments. Check our cleanser for a super affordable option.
How to Prevent Brushes from Getting Rough Again
Once you've restored your brushes to their former glory, you'll want to keep them that way.
Clean them regularly but gently
We know it's a chore, but it's worth it. The best way to prevent stiffness is to never let buildup happen in the first place. Clean your brushes thoroughly at least once a week (more often if you use them daily), and do quick rinses between uses when switching between different products. Use gentle & circular motions instead of harsh scrubbing, and take your time to make sure all product is removed.
Avoid soaking the ferrule
This can't be stressed enough - water getting into the ferrule (that metal band) is one of the fastest ways to ruin a brush permanently. It loosens the glue that holds everything together, causing bristles to shed and potentially making the brush head fall off completely. Always keep the ferrule pointing upward while washing, and focus your cleaning efforts on the bristles themselves. If water does get in there, dry the brush immediately and lay it flat to prevent further damage.
Use proper drying techniques
How you dry your brushes is just as important as how you clean them. Always lay them flat on a towel with the bristles hanging over the edge - this prevents water pooling and allows air circulation. Never use a hair dryer or place them near heat sources, as this can damage the bristles and make them stiff. Reshape the brush head while damp to maintain the proper form, and be patient because rushing the drying process with heat will only cause problems.
Store brushes upright or in protective cases
Proper storage keeps your brushes in good shape between uses. If you store them upright in a container, make sure they're completely dry first and that there's enough space so they're not squished together. Brush rolls or protective cases are actually better for travel and long-term storage because they keep the bristles protected and maintain their shape. Avoid storing brushes in humid environments like bathrooms if possible, as moisture can encourage bacterial growth and make bristles feel musty.
Signs It's Time to Replace Your Brushes
Sometimes a brush is just beyond saving. Knowing when to throw in the towel can save you time and frustration. Here are the telltale signs that it's time to say goodbye and invest in some new tools.
Persistent stiffness despite cleaning
If you've tried deep cleaning, conditioning, and even DIY treatments but your brush still feels like a scrub brush, it's probably time to retire it. This usually happens when the bristles have been damaged beyond repair or when the buildup is so severe that it's permanently altered the structure of the bristles. Don't feel bad about this since even the best brushes have a lifespan, and sometimes the kindest thing is to let them go.
Frayed or shedding bristles
A few loose bristles here and there are normal, especially when brushes are new. But if your brush is constantly shedding or if you can see obvious fraying and splitting of the bristles, it's over. Damaged bristles won't hold product properly, can scratch your skin, and will only get worse over time. Plus, nobody wants random bristles stuck to their face during makeup application, that's just annoying.
Irritation on the skin when using
If your previously comfortable brush suddenly starts feeling scratchy or causes redness and irritation, listen to your skin. This could mean the bristles are damaged, there's bacterial buildup that won't wash out, or the brush has absorbed something that's reacting badly with your skin. Your face is too important to risk with a questionable brush, so when in doubt, toss it out.
FAQs About Softening Makeup Brushes
1. Can you use hair conditioner to soften makeup brushes?
You can, but it's not great long term. Hair conditioner has heavy oils that build up on bristles and attract more dirt. Just make sure you rinse REALLY well.
2. Why do my brushes get stiff even after washing?
You're probably not rinsing enough, using water that's too hot, or your soap is too harsh. Leftover soap hardens when it dries, making brushes stiff. Also if you have hard water, minerals build up on the bristles. Try gentler soap and rinse until the water runs clear.
3. How often should I clean and condition my brushes?
Clean weekly if you use them daily, or after every few uses if you're casual about makeup. Deep clean with conditioner once a month. If they start feeling rough or don't work as well, they need some TLC.
4. Do natural hair brushes need different care than vegan brushes?
Yep. Natural hair brushes are way more delicate - treat them like your own hair. They need more conditioning and can't handle hot water or harsh soaps. Vegan brushes are tougher so they can be easier to maintain.
5. Do vegan brushes soften differently than animal hair?
Vegan brushes bounce back faster from stiffness because they don't soak up as much gunk. But once synthetic bristles are damaged, they're harder to fix. The upside? Good vegan brushes (like our Flawless Foundation brush) stay softer and often last longer than natural hair.
