How To Clean Makeup Brushes With Shampoo And Conditioner Tricks

Cleaning makeup brushes is a non-negotiable step in any beauty routine. Over time, brushes accumulate oils, dead skin cells, bacteria, and leftover product—especially from foundations, concealers, and creams. Neglecting this maintenance can lead to breakouts, uneven makeup application, and premature brush deterioration. While commercial brush cleaners exist, many contain harsh chemicals or come at a premium price. A smarter, gentler, and more accessible solution lies in products already in your bathroom: shampoo and conditioner.

Using shampoo and conditioner to clean makeup brushes isn’t just a DIY hack—it’s a dermatologist-approved method that mimics the way these products cleanse and condition hair. After all, most makeup brushes are made from natural bristles (like goat, sable, or horsehair), which are structurally similar to human hair. This compatibility makes shampoo and conditioner ideal for deep cleaning without damage. With the right technique, you can restore your brushes to near-new condition, save money, and reduce waste—all while ensuring your skin stays healthy.

Why Shampoo and Conditioner Work So Well

Shampoo is formulated to lift oil, dirt, and residue from hair fibers through surfactants—cleansing agents that bind to grease and allow it to be rinsed away. The same principle applies to makeup brush bristles. Most liquid shampoos are pH-balanced and gentle enough for daily use on sensitive scalps, making them safe for delicate brush hairs.

Conditioner, on the other hand, contains moisturizing agents like silicones, oils, and proteins that smooth and soften hair cuticles. When used on brushes, it detangles bristles, restores flexibility, and prevents fraying. This dual-action approach—cleanse with shampoo, condition for softness—mirrors a proper hair care routine and delivers exceptional results for brush maintenance.

“Think of your makeup brushes as an extension of your skincare tools. If you wouldn’t put dirty fingers on your face, don’t use unclean brushes either.” — Dr. Lisa Park, Board-Certified Dermatologist

Step-by-Step Guide to Cleaning Brushes with Shampoo and Conditioner

This method works for both natural and synthetic bristle brushes, though natural-haired brushes benefit the most due to their protein-based structure. Follow these steps carefully to avoid damaging the glue at the ferrule (the metal part holding bristles to the handle).

1. Gather Supplies: Mild shampoo (sulfate-free preferred), conditioner, lukewarm water, a small bowl or cup, a clean towel, and a flat surface.
2. Rinse Bristles: Hold the brush under lukewarm water, pointing downward. Never soak the entire brush—water must not enter the ferrule, as it can loosen the adhesive and cause shedding.
3. Apply Shampoo: Place a pea-sized amount of shampoo in your palm or a small dish. Gently swirl the wet bristles in circular motions to create a lather. Focus on the base of the bristles where buildup hides.
4. Massage Gently: Continue swirling for 30–60 seconds. For dense foundation brushes, use the edge of your palm to lightly press and release bristles, working out trapped product.
5. Rinse Thoroughly: Rinse under running water until the water runs clear. Check the rinse water—if it’s still cloudy, repeat the shampoo step.
6. Apply Conditioner: Use a tiny drop of conditioner. Swirl bristles gently as before. Let sit for 1–2 minutes to penetrate and soften.
7. Rinse Again: Rinse completely until no slippery residue remains. Residual conditioner can attract dust and bacteria.
8. Squeeze and Shape: Gently press excess water from the bristles with a clean towel. Reshape the brush head to its original form.
9. Dry Properly: Lay brushes flat on a towel with bristles hanging slightly over the edge to allow airflow. Avoid upright drying, which can let water seep into the handle.

Tip: Clean foundation and concealer brushes weekly; eyeshadow and powder brushes every 2–3 weeks.

Best Shampoos and Conditioners for Brush Cleaning

Not all hair products are suitable. Avoid anything with heavy sulfates, alcohol, or strong fragrances, as these can dry out bristles or degrade adhesives. Opt for gentle, clarifying formulas designed for fine or sensitive hair.

Type	Recommended Products	Avoid These Types
Shampoo	Johnson’s Baby Shampoo, Aveeno Oat Milk Shampoo, Ouai Detox Shampoo	Clarifying shampoos with high sulfates, dandruff shampoos with salicylic acid
Conditioner	Pantene Pro-V Daily Moisture, SheaMoisture Hydrating Conditioner, baby conditioners	Heavy silicones (e.g., dimethicone-heavy formulas), protein-overload treatments

Baby shampoo is particularly popular among makeup artists for its mild formula and low irritation risk. It cuts through grime effectively while preserving bristle integrity. For deeper cleans, consider a clarifying shampoo once a month—but always follow with conditioner to prevent brittleness.

Common Mistakes to Avoid

• Soaking the entire brush: Waterlogged handles weaken glue and promote mold growth inside the ferrule.
• Using hot water: Heat can warp bristles and loosen adhesive bonds.
• Skipping the conditioning step: Especially for natural hair brushes, skipping conditioner leads to dryness and split ends.
• Drying brushes upright: Gravity pulls water into the handle, causing long-term damage.
• Over-cleaning with harsh products: Daily washing with strong detergents strips natural oils and shortens brush life.

Tip: Rotate your brushes. Use different ones each day so each gets time to dry fully between uses.

Real Example: How a Makeup Artist Transformed Her Kit

Jamila Reyes, a freelance makeup artist based in Austin, used to replace her brush set every four months due to stiffness and shedding. “I was spending $200 every few months,” she says. “Then my mentor showed me how to clean them properly with baby shampoo and conditioner.”

She began cleaning her foundation and stippling brushes weekly, others biweekly. After three months, she noticed less shedding, better blending, and fewer client complaints about patchy foundation. “One of my favorite blush brushes is now two years old—still soft and holds its shape. I’ve saved over $800 in replacement costs alone.”

Jamila also reported fewer instances of clients developing minor breakouts post-application. “It wasn’t just about hygiene—it was about performance. Clean brushes pick up product better and distribute it evenly.”

Frequently Asked Questions

Can I use dish soap instead of shampoo?

No. Dish soap is designed to cut through grease and often contains strong degreasers that strip natural oils from bristles, leading to brittleness and breakage. While it may seem effective initially, repeated use damages brush fibers. Stick to gentle shampoos that balance cleansing with care.

How long should I wait before using a brush after cleaning?

Allow brushes to dry completely—usually 6 to 12 hours depending on thickness and humidity. Using a damp brush can dilute makeup, alter texture, and introduce moisture into product containers, promoting bacterial growth. Speed up drying by placing brushes in a well-ventilated area or using a fan (not a hairdryer, which can melt synthetic bristles).

Is it safe to use conditioner on synthetic brushes?

Yes, but sparingly. Synthetic bristles don’t absorb moisture like natural hair, so they don’t need conditioning as often. However, a light swipe of conditioner occasionally helps prevent static and keeps fibers supple. Always rinse thoroughly to avoid residue buildup.

Pro Tips for Long-Term Brush Care

• Spot-clean between deep cleans: Wipe bristles on a microfiber cloth after each use, especially after liquids.
• Use a brush cleaning mat: Textured silicone mats help agitate bristles against ridges, improving deep-cleaning efficiency.
• Replace brushes when necessary: Even with perfect care, brushes wear out. Signs include excessive shedding, misshapen heads, or persistent odor after cleaning.
• Store brushes properly: Keep them in breathable containers, away from direct sunlight and humidity.

Tip: Label your brushes or store them by function (face, eyes, lips) to maintain hygiene and streamline cleaning schedules.
