It is wash day, the shower is running, and a small voice in your head asks the question every new wearer asks: what if this undoes the curl? The first wash of a new set is a nervous moment, and most of that nervousness comes from not knowing the rules. The good news is that the rules are simple. Learn how to care for curly hair extensions properly, and the curl pattern can stay springy and defined for months.

This guide is a practical, step-by-step routine for anyone who likes to understand what they are doing and why. It covers what to buy, how to wash, detangle, dry, style and sleep, and the habits that quietly flatten a curl without anyone noticing. Think of it as a friendly walkthrough from someone who has seen a lot of curls come through the door.

The End Result: What Good Care Looks Like

Well-kept curly extensions look like part of your head. The curls clump together in defined groups, the ends stay soft, there is no fuzzy halo of frizz at the roots, and the pattern is the same on day 60 as it was on day 2. They hold their bounce after washing, they spring back when stretched, and they can be refreshed in five minutes without a full restyle.

Poor care produces the opposite: loose, stringy curls, tangled knots at the nape, a dry, rough texture and ends that look thin. Most of that damage is avoidable.

What You’ll Need

A small, well-chosen kit does the job. Spending on the right few items is better than collecting many.

• Sulphate-free shampoo: sulphates strip moisture, which extension hair cannot replace from the scalp.
• Rich, silicone-light conditioner: for the lengths only.
• Water-based leave-in cream or milk: to hydrate and define.
• Curl-defining gel or mousse: light to medium hold, alcohol-free.
• Wide-tooth comb and a loop brush: made for detangling extensions without snagging.
• Microfibre towel or cotton T-shirt: terry towels roughen the cuticle.
• Silk or satin bonnet, scrunchie or pillowcase: reduces friction overnight.
• Spray bottle: for water refreshes between washes.
• Diffuser attachment (optional): for faster, gentler drying.

A budget of £40 to £90 covers most of this, and the items last for several months.

Step-by-Step: A Complete Curl-Care Routine

Step 1: Wait Before the First Wash

After fitting, give the attachments 48 hours to set. Washing sooner can loosen bonds or tracks. Until then, keep the hair dry, avoid tight styles and sleep on satin.

Step 2: Detangle Before Getting Wet

Gently loosen knots with fingers, then a wide-tooth comb, starting at the ends. Work in four sections. Doing this before the water prevents tangles from tightening. If the hair is very dry, spritz it lightly with water and a little conditioner first.

Step 3: Wash With Care

1. Rinse the hair with lukewarm water. Hot water roughens the cuticle.
2. Apply shampoo to the scalp only, massaging with fingertips in a pressing motion.
3. Let the suds run down the lengths as you rinse. Do not scrub the extensions.
4. Rinse until the water runs clear.

Wash every 7 to 10 days. Curly hair needs less frequent washing than straight hair, and extension hair gets no help from scalp oil.

Step 4: Condition the Lengths

Apply conditioner from mid-length to ends, keeping it away from bonds, tape or tracks. Comb through gently while the conditioner is in. Leave for three to five minutes, then rinse. A deep-conditioning mask once every two or three washes keeps the hair soft.

Step 5: Apply Leave-In and Define

While the hair is still soaking wet, smooth in a leave-in cream, then a small amount of gel or mousse. Use the “praying hands” method, pressing product along each section, or scrunch upwards towards the roots. This is the moment the curl pattern forms, so do not skip it.

Step 6: Dry Without Disturbing the Curl

Blot, never rub, with a microfibre towel. Then either air dry or use a diffuser on low heat and medium airflow. Avoid touching the hair while it dries, since touching causes frizz. Once it is fully dry, a gentle scrunch breaks the gel cast and leaves soft, defined curls.

Step 7: Refresh Between Washes

Mist the hair lightly with water mixed with a drop of leave-in, scrunch and let it dry. Do this instead of washing again. Re-wetting a whole head every day is the quickest way to dry out extension hair.

Step 8: Protect at Night

Gather the hair into a loose high pineapple with a satin scrunchie, or sleep in a satin bonnet. Never go to bed with wet hair; damp roots loosen attachments and encourage tangles.

Curly Texture vs Heat-Set Curl: A Commonly Confused Alternative

Many buyers assume all curly extensions are the same. They are not, and the care routine differs.

• Naturally curly hair: the curl is part of the strand’s structure. It returns after each wash and responds well to moisture.
• Heat-set or chemically processed curl: straight hair that has been curled by heat or perm solution. The curl can relax in a few washes, especially with humidity or sulphate shampoos.

Ask your supplier which type you have. Processed curls need gentler washing, more protein-free hydration and little to no heat. Natural curls tolerate more, but still benefit from the routine above.

What the Pros Know: Wet a single strand and watch what happens. A natural curl springs up and holds its shape. A heat-set curl stretches out and looks limp. If your extensions behave like the second type, adjust the routine and stop using hot tools.

Styling Curly Extensions Without Losing Definition

• Wash-and-go: the simplest option. Apply product soaking wet and let the hair dry untouched.
• Twist-out or braid-out: set damp hair in twists overnight for stretched, defined curls.
• Pineapple: a high, loose ponytail for sleeping or for a quick volume lift.
• Finger coiling: wrap small sections around a finger to define individual curls.
• Heat styling: best avoided. If you must, use a heat protectant and stay below 150°C.

Where Professional Help Fits In

Home care covers most of the routine, but a few jobs belong with a professional: the maintenance move-up, trimming and shaping, and any colour work. Salons that fit curly hair extensions by Ivana Farisei include a care briefing in the appointment, so you leave with a routine tailored to your texture instead of a generic leaflet.

Ivana Farisei stylists also trim curly sets dry, curl by curl, which preserves the shape. Cutting wet hair makes curls look longer than they are and leaves them uneven once dry. If you ask only one question at your first appointment, make it whether the set will be dry-cut after fitting.

Choosing Products by Curl Type

Not every curl wants the same products. Weight is the main variable: too heavy and the curl drops, too light and it frizzes.

• Loose waves and curls (2B to 3A): lightweight mousse or foam and a spray leave-in. Heavy creams pull the curl out.
• Defined curls (3B to 3C): a leave-in cream plus a gel with medium hold. Layering gives definition without crunch.
• Coils (4A to 4C): richer creams, butters and a sealing oil on the ends, with a custard or gel for definition.

Read ingredient lists with a few rules in mind. Avoid drying alcohols (listed as “alcohol denat.” or “SD alcohol”) high on the list, avoid heavy mineral oil and wax near attachments, and look for glycerin, aloe, panthenol and plant oils. Fatty alcohols such as cetyl or stearyl alcohol are fine; they are moisturising, not drying.

Test Before You Commit

Try a new product on a small section first, dry it fully and judge it the next morning. It takes one extra day and saves a whole set from a bad reaction. DIY enthusiasts often keep a simple log of product, amount and result, which makes the next wash day easier.

Deep Conditioning: The Weekly Habit That Matters Most

Extension hair is cut off from the scalp, so it cannot replenish itself. A weekly or fortnightly treatment replaces what daily life takes away.

1. Apply a moisture mask to damp, detangled hair, from mid-lengths down.
2. Cover with a shower cap and wrap in a warm towel for 15 to 20 minutes.
3. Rinse with cool water to close the cuticle.
4. Proceed with leave-in and styling as normal.

Alternate between moisture masks and light protein treatments, roughly one protein for every three moisture sessions. Too much protein stiffens curls and causes brittleness; too little leaves the hair limp and weak. Watch how the hair feels: stretchy and mushy means more protein, rough and stiff means more moisture.

Seasonal Adjustments

Spring and Summer

Humidity makes curls swell and frizz. Use lighter products, a stronger-hold gel and an anti-humidity serum on the lengths. Wear a hat in direct sun and rinse after swimming. Wash slightly more often if sweat or sunscreen builds up near the scalp.

Autumn and Winter

Dry air and wind strip moisture. Switch to richer creams, add a weekly mask and cover the hair under a satin-lined hat. Dry indoor heating also causes static, which a drop of leave-in on the palms smooths away.

Travel, Gym and Swimming

• Travelling: decant products into small bottles, pack a satin bonnet and a wide-tooth comb, and avoid tight ponytails on long flights.
• Exercise: tie the hair loosely, rinse sweat from the scalp afterwards and dry the roots thoroughly.
• Swimming: wet the hair first so it absorbs less chlorine, apply leave-in, wear a cap if possible, and shampoo and condition afterwards.
• Hot tubs and sea water: rinse straight away, then deep condition within a day or two.

When Curls Tangle: A Rescue Plan

Even careful wearers meet a knot sometimes. Panic and brute force make it worse. The calmer approach works almost every time.

1. Stop brushing. Pulling on a knot tightens it and drags on the attachment.
2. Saturate the knot with conditioner and a few drops of oil, away from bonds or tape.
3. Hold the hair above the knot with one hand to protect the root.
4. Loosen the knot with fingers, working from the edges inwards.
5. Once loose, use a wide-tooth comb, starting from the ends.
6. If the knot sits right at the attachment, stop and book a visit.

A hard mat at the root is not a DIY job. A stylist can free it with solvent and patience, whereas cutting it out risks taking natural hair with it.

Keeping a Simple Care Calendar

DIY thinkers tend to like a schedule. This one fits most routines.

• Daily: a quick finger detangle in the morning, satin protection at night.
• Every 2 to 3 days: water refresh with a little leave-in.
• Every 7 to 10 days: full wash and condition.
• Every 2 to 3 weeks: deep conditioning mask.
• Monthly: a clarifying wash on the lengths if build-up appears.
• Every 6 to 10 weeks: professional maintenance and trim.

Ivana Farisei gives clients a version of this calendar at the first fitting and adjusts it for their texture, since a loose wave and a tight coil need quite different rhythms. It is a small piece of paper that prevents most of the questions people send afterwards.

Why Match and Care Go Together

Care only works if the texture is right to begin with. A set that does not match your curl pattern will always need extra styling, which means more product, more heat and more handling. For the best results, choose a team that matches the curl first and gives aftercare advice afterwards, like the stylists at Ivana Farisei, who see both as one process. When the pattern is right, the routine in this guide is usually enough, and the curl stays where it should.

Extending the Life of Your Set

The cheapest set is the one that lasts. Several small habits add months to the life of curly extensions, and most of them cost nothing.

Rotate Your Styles

Wearing the same style every day puts constant stress on the same sections. Alternate between a wash-and-go, a twist-out and a loose pineapple, so no single area bears all the tension. Give the nape and hairline a rest by avoiding tight styles for several days each week.

Store Spare Pieces Properly

Owners of clip-ins or a spare set should keep them detangled and dry in a satin bag or on a hanger, away from sunlight and humidity. Storing them loose in a drawer leads to tangles and flattened curls. Rinse and condition them every few wears, just as you would fitted hair.

Know When to Trim

Curly ends thin out over time. A trim of 1 to 2 cm every three months keeps the shape full and prevents split ends from travelling up the strand. Always trim dry, curl by curl, so you can judge the result as the hair will actually fall.

Track the Condition

Photograph your hair monthly in the same light. Comparing the pictures shows slow changes in definition, volume and length that daily mirror checks miss. Share the images with your stylist, who can then tell whether a change is normal ageing, a care issue or a sign that the set is nearing retirement. Teams such as Ivana Farisei are glad to review them at a maintenance visit, and it makes the conversation far more precise.

Common Mistakes to Avoid

• Brushing dry curls. It breaks the pattern and creates frizz. Detangle wet, with conditioner.
• Using sulphate shampoo. It strips moisture and shortens the life of the set.
• Heavy oils on attachments. Oil near bonds or tape can loosen the hold.
• Washing too often. Over-washing dries the hair and flattens the curl.
• Rubbing with a towel. It roughens the cuticle and breaks up curl clumps.
• Sleeping on cotton. Friction causes tangles and frizz.
• Skipping maintenance appointments. Overgrown attachments tangle and pull.
• Straightening to match. Heat can permanently loosen a curl pattern.

Troubleshooting: Fixing Problems as They Appear

Frizz at the Roots

Usually caused by friction or drying with a rough towel. Smooth a little gel over the roots while damp, and sleep on satin.

Curls Looking Limp

Often a sign of product build-up or too much conditioner. Use a clarifying wash once a month, avoiding the attachments, and apply less product at the roots.

Tangles at the Nape

The nape rubs against collars and pillows. Detangle gently with conditioner, protect with a satin scarf and consider an earlier move-up if tangles keep returning.

Dry, Straw-Like Ends

Extension hair has no oil supply. Add a weekly mask and seal ends with a light, plant-based oil. A trim of 1 to 2 cm often resets the look.

Frequently Asked Questions

How often should I wash curly hair extensions?

Every 7 to 10 days is typical. Refresh with water and leave-in between washes.

Can I use heat on curly extensions?

Sparingly. Heat can loosen the curl, especially on processed hair. Use a protectant and keep temperatures low.

How long do curly hair extensions last?

With care, six to twelve months. Maintenance move-ups are needed every six to ten weeks.

Can I swim with curly extensions?

Yes, after the first 48 hours. Wet the hair with fresh water first, apply leave-in, and rinse and condition afterwards.

Why do my extensions look different from my natural curls?

Texture, density or shrinkage may not match. A specialist can assess the difference and adjust with trimming, product or a replacement piece.

Next Steps

Start with the small kit, practise the routine over your first two washes and take photos of the results, so you can see what works. Book your first move-up before leaving the salon, and bring those photos with you. A stylist can usually spot at a glance whether a problem is product, technique or texture, and can fix it in minutes. If you are still shopping for a set, choose a team that treats curl care as part of the service, not an afterthought.
