Before you start: what actually happens to hair after extensions
To care for hair extensions properly, it helps to understand what your routine is dealing with. Natural hair is nourished from the follicle, which produces sebum and delivers nutrients along the entire length. Attached extensions don't have this mechanism. They're fixed close to the scalp through a specific bonding method, but every centimetre of length below the bond depends entirely on what you apply from the outside.
This means that a standard care routine — shampoo, the odd conditioner, full-blast hairdryer — might work fine on natural hair. On extensions, it tends to show up fairly quickly as dull, tangled ends and weakened bonds. The good news is that changing a few habits can make a big difference.
Step 1 — Washing: technique matters more than product
Washing is one of the moments where it's easy to make a mistake — and one of the most important steps in caring for extensions. The problem isn't usually the shampoo itself, but how you wash. Vigorous scrubbing, circular motions and friction cause tangling, and applying shampoo directly onto the bonds can, depending on the method, loosen them.
- 01
Brush before washing
Before you step into the shower, gently brush your hair from the ends upward. Wet strands are much harder to detangle and more prone to mechanical damage — it's worth removing knots while the hair is still dry.
- 02
Shampoo: scalp only
Apply shampoo to the scalp and gently massage it in with your fingertips — no scrubbing, no circular motions. As it rinses out, the product will pass through the length of your hair and cleanse it sufficiently. Don't scrub the lengths, and don't pile your hair into a bundle on top of your head.
- 03
Rinsing: thoroughly and slowly
Rinse for longer than you think you need to. Shampoo residue left near the bonds can irritate the scalp and weaken the bond. Direct the water from top to bottom — in line with the hair cuticle.
- 04
Conditioner: from mid-length down
Apply conditioner from mid-length down — especially to the ends. Avoid applying it directly to the bonds (particularly keratin or tape-in bonds). Leave it on for a few minutes, then rinse with cooler water — this seals the cuticle and adds shine.
- 05
Gentle towelling
Squeeze the water out — don't rub. Wrap or press a towel against your hair rather than rubbing vigorously. A microfibre towel or an old cotton T-shirt handles this better than a standard terry towel.
Step 2 — Drying and styling: heat is the enemy of bonds
After washing, extended hair is briefly at its most vulnerable — the cuticle is open, the bonds slightly saturated. This is exactly when irreversible damage is most likely — both mechanical and thermal. Good habits at this stage make a huge difference.
Careful drying
Protects the bonds and structure
- Start with the lowest airflow and heat setting, then increase gradually
- Hold the hairdryer around 15–20 cm from your head
- Direct the airflow from top to bottom (not against the hair)
- Dry the bonds fully — wet bonds are more prone to damage
Air drying
Gentlest option for the structure
- Ideal when you're not in a rush
- Remember to gently brush before drying
- Don't go to bed with wet extensions — moisture near the bonds encourages tangling and can lead to dull ends
If you use straighteners, a crimper or curling tongs — apply heat protection every time, not "now and then". Apply a product with heat protection to the mid-lengths and ends before every use of styling tools. Avoid running a hot plate over the bonds — especially with the keratin method.
Step 3 — Brushing: always from the ends
Brushing looks like an obvious step, but it hides plenty of mistakes. With extensions, one rule is non-negotiable: always brush from the ends upward, never the other way round.
- Use a brush with soft, flexible bristles (a so-called extension brush) or a wide-tooth comb — a hard brush with metal pins can catch on the bonds.
- Brush in sections: hold the hair near the bond with one hand, brush the ends with the other — holding it steady protects the bond from being pulled out.
- Brush daily — at least morning and evening. Small tangles you ignore today become knots tomorrow.
- Before bed, always braid your hair loosely or tie it into a loose bun — this significantly reduces tangling while you sleep.
- Don't brush wet hair with a standard brush — while it's damp, use a wide-tooth comb or a brush designed for wet hair.
Step 4 — Hydration and nourishment: what the bond can't give you
This is the step that's most often skipped or treated as an afterthought — yet with extensions, it's an absolute foundation. Because attached hair doesn't receive sebum from a follicle, it needs to receive it from you.
In practice, this comes down to two habits: regular use of a hydrating conditioner or mask (at least once a week, on the mid-lengths and ends) and a light oil or serum applied to the ends after drying. Both steps complement each other — the mask hydrates the structure, the oil seals it in and protects against moisture loss.
Mask / intensive conditioner
Hydration from within
- Use 1–2 times a week on the mid-lengths and ends
- Leave on for at least a few minutes (or longer under a shower cap)
- Choose hydrating, lightweight formulas — avoid heavy silicones near the bonds
Oil / serum for the ends
Protection and shine
- Apply to dry or slightly damp ends daily or every other day
- Just a few drops are enough — less is more
- Silicone serum adds shine and thermal protection; plant oils hydrate more deeply
What NOT to do — the most common mistakes
Many people care for their extensions with good intentions, but a handful of old habits from before — and these are exactly what shorten the bonds' lifespan by weeks. Here's a short list of mistakes worth avoiding.
Most of these mistakes don't cause immediate disaster — the effects build up over weeks. That's exactly why they're easy to ignore. But that's also why it's worth changing them straight after your salon visit, rather than waiting until things get worse.
When to go back to the salon — signs not to ignore
Home care maintains the result — but it doesn't replace professional checks. Bonds grow out along with your natural hair, so a follow-up visit after a few weeks is standard, not a luxury. There are also signs that clearly say: "book an appointment now."
- The bonds are visibly high up — your natural hair has grown enough that the bonds have shifted noticeably away from the scalp; this is the point to top up or reposition.
- One or several bonds have suddenly become loose or "move around" — this can result from a care mistake or natural wear, but it's worth having it assessed professionally.
- The ends are very dry, dull and barely respond to nourishment — a sign that the hair structure is under significant strain and needs a specialist's assessment.
- You feel pulling or pain near the bonds — extensions shouldn't hurt; if they do, it may mean a bond is too tight or positioned too close to the scalp.
- You notice matting forming around the bonds — especially with glue-free methods (micro-rings, tape-ins); this is an early sign that the bond needs adjusting.
Regular follow-up visits aren't a cost — they're an investment in making sure your extensions can be removed later without damaging your natural hair. A specialist will assess the condition of the bonds and your hair, and adjust your care plan for the weeks ahead if needed.
