Most extension damage doesn't happen during styling or sleeping—it happens during brushing. And the frustrating part? It's completely preventable.
The brushing technique that works perfectly on natural hair can destroy extensions in weeks. Extensions don't receive oils from your scalp the way your natural hair does, so they're more vulnerable to friction, tangling, and breakage. Every stroke matters more than you think.
This feels counterintuitive if you've spent your whole life brushing from root to tip. But with extensions, you need to work in reverse.
Begin at the ends of your hair—the last two to three inches—and gently work through any tangles. Once that section moves freely, move up a few inches and repeat. Continue working your way up toward the roots in small sections.
Why does this matter so much? When you brush from the top down, you're pushing every tangle you encounter downward, compacting them into bigger knots at the ends. You're also putting tension on your attachment points (whether that's tape, bonds, or wefts) with every snag. Over time, this stress can cause slipping, matting near the roots, or even hair loss at the attachment site.
Starting at the bottom isolates each tangle so you can work through it without creating a chain reaction of knots above and below.
This is the technique that separates people who get eight weeks from their tape-ins from people who barely get four.
When brushing near your roots or mid-lengths, use your free hand to gently hold the hair just above the attachment point. This creates a buffer between your brush and the bond, tape, or weft. The tension from brushing stays in your hand rather than pulling on the extension itself.
For tape-in extensions, hold flat against your scalp right above the tape sandwich. For hand-tied wefts, cup your hand over the beaded row. For keratin bonds, pinch just above each bond as you brush past it.
This takes an extra thirty seconds but dramatically extends the life of your install.
Not all brushes work for extensions—and some will actively ruin them.
What to use: A loop brush (sometimes called an extension brush) or a wet brush with flexible bristles. Loop brushes have looped bristles without the traditional ball tips, which glide through extensions without catching on bonds or tapes. The Bombshell Extensions detangling brush is designed specifically for this.
What to avoid: Brushes with ball-tipped bristles, fine-tooth combs, or anything with rigid plastic bristles. Ball tips catch on attachment points and yank. Fine-tooth combs create too much friction on dry extension hair. Paddle brushes with stiff bristles can pull extensions right out of tape or loosen weft beads.
Natural boar bristle brushes work well for smoothing and distributing oils, but they're not great for detangling. Use them as a finishing brush, not your primary tool.
Extensions are most fragile when wet. The hair cuticle swells with water, making it more prone to damage and tangling. Brushing aggressively through wet extensions can cause permanent texture changes—frizz that won't go away, stretched-out waves, or a rough feel that no amount of conditioning will fix.
Before you brush wet extensions, gently squeeze out excess water with a microfiber towel or cotton t-shirt. Never rub. Apply a leave-in conditioner or detangling spray, focusing on the mid-lengths and ends.
Then use your fingers first. Gently work through any major tangles with your hands before picking up a brush. Once the big knots are out, use your loop brush with the same bottom-to-top technique, moving even slower than you would on dry hair.
Some people prefer to only brush extensions when they're completely dry. If your extensions are prone to tangling, try this approach and see if it helps.
Twice a day minimum: once in the morning and once before bed. If you're active, exercise, or spend time outdoors, add a midday brush.
The morning brush removes tangles that formed overnight (even with proper sleeping techniques, some tangling is normal). The evening brush prevents those tangles from setting in and becoming matted while you sleep.
Skipping brushing is where things go wrong fast. Extensions that aren't brushed daily develop mats near the attachment points that become impossible to remove without cutting. This is especially true for hand-tied wefts and keratin bonds, where hair can wrap around the attachment and create a dense knot against your scalp.
When you hit a tangle that won't budge, resist the urge to power through it. Stop, spray it with a detangling product, wait thirty seconds, and try again with your fingers before returning to your brush.
If a tangle is right at an attachment point, isolate it carefully. Hold above and below the tangle, and work through it with the end of a rat-tail comb or your fingers rather than pulling a brush through it.
Severe matting near the roots usually requires professional help. If you can see or feel a dense mat forming at your attachment points, book a maintenance appointment. Trying to brush out a mat yourself often causes more damage than it fixes.
Morning and night, this takes under two minutes:
Spray lightly with a leave-in or detangler. Start at the ends, work up in sections. Hold attachment points as you brush past them. Finish by smoothing from mid-length to ends.
That's it. Consistent gentle brushing will keep your extensions tangle-free, extend the life of your install, and make your maintenance appointments faster and easier. The small investment of time every day pays off in weeks of extra wear.
