The number one reason extension clients come back unhappy isn’t about the hair quality or the installation. It’s about care. They washed their extensions like they wash their own hair, and within two weeks the extensions looked like something the cat dragged in.
I can’t count how many times I’ve had this conversation. A client sits down, I look at their extensions, and I can immediately tell what went wrong. Too much product. Wrong shampoo. Brushed wet. Slept with it loose. The list goes on.
So here’s the routine I give every single extension client. It doesn’t matter if they have tape-ins, keratin bonds, or sewn-in wefts. The basics are the same. Follow this and your extensions will last months. Ignore it and you’ll be buying new hair in weeks.
Brushing: Before You Wash, Not After
Always brush extensions before washing. When hair is wet, it’s at its weakest. Brushing wet extensions stretches and breaks the strands. So start dry.
Use a loop brush or a boar bristle brush. Regular paddle brushes with ball-tipped bristles snag on the bonds or tapes and can pull them loose. A loop brush glides right over the attachment points.
Start at the ends and work your way up. Don’t yank through tangles from the top down. Hold the hair mid-shaft to support it, then gently work out knots from the bottom. This takes longer but saves hair from unnecessary breakage.
Washing: Less Often Than You Think
Here’s where most people go wrong. They wash their extensions every day, or every other day. That’s too much. Extensions don’t have the natural oils from your scalp running down them. They dry out faster with each wash.
I tell clients to wash twice a week, three times max. If they exercise daily, they can rinse with water between washes and use a dry shampoo at the roots. But full washing with shampoo should be limited.
When you do wash, use sulfate-free shampoo. Sulfates are harsh detergents that strip moisture from the hair and break down adhesives in tape-ins and bonds. They also fade color faster. A sulfate-free shampoo cleanses gently without wrecking the hair or the attachment.
The technique matters too. Don’t pile hair on top of your head and scrub like you’re washing a sweater. That creates tangles. Instead, wet the hair thoroughly, apply shampoo to the roots, and let it run down the lengths as you rinse. Smooth it through with your palms, don’t rub or twist.
Conditioning: Mid-Shaft to Ends Only
This rule is non-negotiable for tape-ins and pre-bonded extensions. Never put conditioner on the roots or near the bonds. Conditioner contains oils and silicones that break down adhesives. I’ve seen tape-ins slide right out after a client massaged conditioner into her roots.
Apply conditioner from the mid-shaft down to the ends. The ends are the oldest, driest part of the hair and need the most moisture. Leave it in for 2 to 3 minutes, then rinse thoroughly. Any residue left behind will make the hair feel greasy and look flat.
For clip-ins that you’ve removed, you can condition more freely since there are no bonds or tapes to worry about. But still, don’t soak the clips in conditioner. Rinse them clean.
Drying: Pat, Don’t Rub
After washing, gently squeeze excess water out with your hands. Then wrap the hair in a microfiber towel or a cotton t-shirt. Don’t use a regular bath towel and don’t rub. Rubbing creates friction, which causes frizz and tangles.
Let the hair air-dry as much as possible. If you need to blow-dry, use a low heat setting and point the nozzle downward to smooth the cuticle. Blow-drying on high heat roughs up the cuticle and makes extensions look dull and frizzy over time.
Never go to bed with wet extensions. This is the most damaging thing you can do. Wet hair tangles, and sleeping on it creates mats that are nearly impossible to brush out. I’ve had clients come in with extensions that looked like felt because they slept with wet hair. Dry your hair completely before bed. Every time.
Styling: Heat Protection Is Not Optional
If you’re going to use a curling iron, flat iron, or hot rollers, you need a heat protectant. No exceptions. Extensions don’t have the same natural moisture as your own hair. Heat damage happens faster and is permanent.
Spray or apply the protectant before styling, and keep your tool temperature below 180 degrees Celsius, or about 350 Fahrenheit. Higher temperatures will scorch the hair, especially if it’s been colored or processed.
Avoid applying direct heat to the bonds or tapes. The keratin in fusion bonds can melt under a flat iron. Tape adhesive can break down under a curling iron. Keep your tools on the lengths and ends, away from the attachment points.
Sleeping: Braid It or Lose It
I tell every client to sleep with their hair in a loose braid. A ponytail works too, but a braid is better because it keeps the hair contained without creating tension on one spot. Sleeping with hair loose means it tangles overnight, and you’ll spend 20 minutes brushing out knots in the morning.
A silk or satin pillowcase helps too. Cotton creates friction that dries out hair and causes frizz. Silk lets the hair glide across the surface without catching. It’s a small investment that makes a noticeable difference.
Products to Use and Products to Avoid
Here’s a quick reference I give clients:
Use: Sulfate-free shampoo, moisturizing conditioner (mid-shaft to ends), leave-in conditioner spray, argan oil or lightweight serum for the ends, heat protectant before styling.
Avoid: Anything with sulfates, alcohol-based products near the bonds, oil-based products near the roots, chlorine and salt water without protection, purple shampoo on extensions (it can dry them out and cause brassiness).
If you swim, coat your hair in conditioner before getting in the water and wear a swim cap. Chlorine is brutal on extensions. Salt water dries them out. If you can’t avoid it, rinse immediately after and deep condition.
How Often to Deep Condition
Once a week, use a deep conditioning mask. Apply it from the mid-shaft to the ends, leave it in for 10 to 15 minutes, then rinse thoroughly. This keeps the hair hydrated and prevents the ends from drying out and splitting.
For clip-in extensions that aren’t being worn, store them laid flat or hung on a hanger. Don’t stuff them in a bag. Brush them before storing and give them a light conditioning spray to keep them moisturized between wears.
Look, I know this sounds like a lot. And honestly, it is more work than just washing your own hair. But the payoff is extensions that look good for months instead of weeks. The clients who follow this routine are the ones who come back thrilled with how their hair looks. The ones who don’t are the ones who tell me their extensions “didn’t last.” Nine times out of ten, it wasn’t the hair. It was the care.
