Your hair extensions look stunning the day you leave the salon—but proper maintenance is what keeps them looking that way for weeks or months. Neglect your extensions, and you'll face matting, shedding, and a costly early replacement. Here's exactly what you need to do each week to protect your investment and extend their lifespan.
Wash Your Extensions Carefully
Hair extensions require gentler handling than natural hair. Wash them once per week (or every 10–14 days if your hair is very dry) using sulfate-free shampoo and conditioner designed for extensions or color-treated hair. Sulfates strip moisture and weaken the bonds that hold extensions in place.
Use lukewarm water, not hot, which can loosen adhesive bonds on tape-in or glued extensions. Apply shampoo to the roots and gently squeeze downward along the hair shaft—never scrub or massage the attachment area. Rinse thoroughly to avoid product buildup, which makes extensions look dull and feel heavy.
For clip-in extensions, you can wash them separately in a sink or basin. Submerge them gently, work shampoo through, and rinse until water runs clear. Let them air dry on a towel afterward.
Conditioning & Deep Treatments Matter
Extensions lack a natural scalp oil supply, so they dry out faster than your biological hair. Apply conditioner from mid-shaft to ends every wash day. Leave it on for 2–3 minutes before rinsing.
Once weekly, use a deep conditioning mask or oil treatment. Popular options include argan oil, coconut oil, or protein-based masks (like those from brands such as K18, Olaplex, or Bonacure). Apply these treatments to your extensions only—avoid the root area and attachment zones—and leave them on for 15–30 minutes.
Budget $15–$40 monthly for a quality deep conditioner specifically formulated for extensions. Cheaper products often contain silicones that build up and weigh hair down.
Detangle Without Damage
Matting and tangling destroy extension lifespan. Detangle twice weekly using a wide-tooth comb or paddle brush designed for extensions. Always start at the ends and work upward, holding the hair at the roots to avoid putting stress on the attachment points.
Never comb extensions while they're wet; hair is most fragile then. Wait until they're at least 80% dry. For stubborn tangles, lightly spray a detangling spray (around $8–$15) or mix a small amount of lightweight conditioner with water in a spray bottle.
Brush gently before bed too. Extensions tangle easily while you sleep, and morning tangles require aggressive combing that weakens bonds.
Protect While You Sleep
How you sleep directly impacts extension longevity. Braid your extensions or put them in a loose bun before bed. Sleeping on extensions unprotected causes friction that leads to matting and shedding.
Some stylists recommend silk or satin pillowcases ($15–$30) to reduce friction further—regular cotton pillowcases create static and tangling. If you wear a bonnet or silk cap while sleeping, that's even better.
Weekly Styling & Heat Protection
Limit heat styling to 2–3 times weekly. Always use a heat protectant spray before blow-drying, flat-ironing, or curling. Apply it generously to mid-lengths and ends.
Avoid stacking extensions in tight ponytails or buns in the same spot every day; rotation prevents strain on specific bonds. Sleep-in styles like braids are fine, but alternate which side you braid on.
Watch for Red Flags
Inspect your extensions weekly for shedding, loose bonds, or matting. A few shed hairs are normal, but if you're losing chunks of hair or seeing visible gaps at attachment points, contact your stylist immediately. Loose bonds may only cost $15–$50 per section to repair, but waiting can make the problem worse.
Check-in appointments with your stylist should happen every 4–8 weeks depending on extension type. During these visits, they'll tighten bonds, trim split ends, and assess overall health.

Frequently Asked Questions
Q: Can I use regular drugstore shampoo on my extensions? No—regular shampoo contains sulfates and harsh cleansers that strip moisture and weaken bonds. Always use sulfate-free or extension-specific formulas.
Q: How often should I get my tape-in extensions reinstalled or adjusted? Tape-ins typically need reinstallation every 6–8 weeks as your natural hair grows. Between reinstalls, monthly maintenance appointments ($30–$80) keep them secure.
Q: What's the best way to remove tangles from clip-in extensions? Detangle with a wide-tooth comb or extension brush when extensions are dry or nearly dry, starting at the ends and working upward. Use a lightweight detangling spray if needed.
