How to Clean a Hairbrush: Step-by-Step Methods for Better Hair and Scalp Health
Fresh bristles glide through locks, removing residue and boosting root vitality.
Your hairbrush is an essential tool in your daily hair care routine, but over time, it collects hair, oils, product residues, and environmental debris that compromise its effectiveness and hygiene. Regular cleaning keeps your brush working its best, protects your scalp, and helps you maintain cleaner, shinier hair. This comprehensive guide explains why, how, and how often to clean your hairbrush, along with tips tailored to every brush type and answers to common hairbrush cleaning questions.
Why You Should Clean Your Hairbrush
The hairbrush you use daily does more than tame tangles and style locks—it collects loose hairs, oils, skin cells, product deposits, lint, and dust over time. If these aren’t removed regularly, you risk brushing all this dirt and gunk back into freshly washed hair, leading to:
- Product Buildup: Hairsprays, gels, and leave-in products cling to bristles and transfer back to your hair, making it look dull or greasy.
- Oil Accumulation: Natural scalp oils build up, trapping more dirt and leading to scalp imbalance.
- Dead Skin and Dandruff: Skin flakes accumulate, increasing the risk of irritation or bacteria growth.
- Environmental Particles: Dust and airborne particles can stick to dirty bristles, creating a breeding ground for germs.
Regularly cleaning your brush keeps your scalp and hair healthier, ensures better styling results, and can even prolong the life of your brush.
How Often Should You Clean Your Hairbrush?
The frequency depends on your hair type, how often you use styling products, and how much you shed. General guidelines:
- Remove trapped hair: After every use or at least several times per week.
- Full cleaning: Once a week if you use styling products regularly, every two weeks for minimal use, or at least monthly for rarely used brushes.
If you notice sticky residue, lint, or visible buildup before your regular schedule, it’s time to clean your brush sooner.
What You Need to Clean a Hairbrush
Gather the following tools and supplies before you begin:
- Bowl or bathroom sink
- Gentle shampoo or clarifying shampoo
- Baking soda (for extra cleaning power, optional)
- White vinegar (optional, for tough residue)
- Old toothbrush or small brush-cleaning tool
- Rat tail comb, pen, or pointed object (for removing hair)
- Scissors (for cutting tangled hair)
- Cotton swabs or small cloth (for handle and crevices)
- Clean towel (for drying)
Step-by-Step Guide: How to Clean Your Hairbrush
Step 1: Remove Hair From the Brush
Use your fingers, a comb, or a pointed tool like a rat tail comb, pen, or pencil to gently lift and pull away as much trapped hair as possible. For stubborn tangles:
- Use scissors to snip any matted knots.
- For deeply tangled sections, insert the pointed end of a comb beneath the hair, lifting it upward.
- Be gentle to avoid damaging the bristles and padding.
Step 2: Prepare the Cleaning Solution
Fill a bowl or your bathroom sink with warm water. Add a few drops of gentle shampoo or clarifying shampoo, swirling to create suds. For additional cleaning power, add one to two teaspoons of baking soda. To address persistent sticky residues, mix in a small amount of white vinegar.
What others are reading
- If you have a plastic or fully synthetic brush, you’ll be able to submerge the whole brush.
- If your brush has a wooden handle, cushioned base, or delicate finish, do not fully submerge. Only the bristles should be soaked to avoid water damage.
Step 3: Soak and Scrub
- For synthetic or plastic brushes: Place the brush in the water for 10 minutes, completely submerging the bristles to loosen residue. Swish the brush around to help release dirt.
- For wooden brushes or brushes with padded bases: Dip the bristles, bristle-side down, into the cleaning solution, taking care not to soak the handle or base.
- Use an old toothbrush or brush-cleaning tool to scrub between the bristles and around the base, where buildup is hardest to reach. If you see sticky white or dark residue, pay extra attention to these areas.
- Dip back into the solution as needed and scrub the brush handle and sides with a cloth or toothbrush.
Step 4: Rinse Thoroughly
- Rinse the brush under running lukewarm water to wash away all soap, debris, and residue.
- Give special attention to brushes with cushion bases—tilt and gently squeeze to remove trapped water.
Step 5: Wipe and Dry
- Wipe any product or stickiness from the handle with a towel. Use a slightly dampened cotton swab to clean creases and edges.
- Pat the brush dry gently.
- Allow the brush to finish drying bristle-side down on a clean towel. This prevents moisture from collecting at the base and discourages bacteria, mildew, or mold.
- Let wooden brushes air dry completely before reuse.
How to Remove Sticky Buildup and Product Residue
For stubborn product residue or stickiness, use a more targeted approach:
- Add a few drops of clarifying shampoo to warm water and soak just the bristles (not wooden handles) for 10–15 minutes.
- Scrub with an old toothbrush, focusing on the base between bristles.
- For extreme buildup (on plastic or metal brushes only), dampen a cotton ball or soft cloth with 70% isopropyl alcohol and wipe bristles and base. Allow to sit for one minute, then scrub and rinse thoroughly.
- Always air dry with bristles facing down.
These steps help prevent product transfer into your hair and prolong the life of the brush.
Special Instructions by Brush Material
| Brush Type | Cleaning Tip | Precautions |
|---|---|---|
| Plastic/Synthetic | Safe to soak entirely. Use shampoo/baking soda/vinegar blends. | None. Rinse well. |
| Wooden Handle | Dip only bristle area. Avoid submerging wood. | Over-soaking can crack or warp wood/finish. |
| Natural Bristle (Boar, etc.) | Use gentle shampoo. Brief soaks, thorough drying. | Don’t soak base. Use minimal water to avoid softening glue. |
| Paddle/Cushion | Soak bristles only, squeeze cushion gently to remove water. | Don’t submerge air-vented pads. |
| Metal | Soak bristles, wipe with alcohol for sanitizing. | Dry thoroughly to discourage rust. |
Expert Tips on Cleaning and Maintenance
- Make it a habit: Add cleaning brushes to your regular self-care or cleaning days.
- Replace brush when needed: If bristles are bent, broken, or falling out, it may be time for a new brush.
- Don’t share brushes: Sharing can transfer oils, dandruff, and bacteria, risking scalp irritation or infection.
- Keep a brush-cleaning tool or comb handy: Regular hair removal after each use simplifies deep cleaning later.
Frequently Asked Questions (FAQs)
How often should I clean my hairbrush?
Remove hair every few days, and deep-clean brushes weekly if you use hair styling products, or at least monthly for occasional use.
Can I use dish soap or hand soap instead of shampoo?
A gentle shampoo is preferred as it cleans residue without damaging natural or synthetic bristles, but mild dish soap works in a pinch for synthetic brushes only.
How do I clean a brush with a wooden handle?
Do not soak wooden handles—just dip the bristles into the cleaning solution, keeping the handle as dry as possible. Wipe the handle with a damp cloth if needed.
What kills bacteria on hairbrushes?
A thorough cleaning with shampoo, and for plastic/metal brushes, a wipe-down with 70% isopropyl alcohol, will kill most germs and bacteria. Always rinse and dry fully before reusing.
How do I know if my brush needs replacing?
If bristles are permanently bent, missing, or the base is cracked, no amount of cleaning will help—replace the brush for best results.
