Hair extensions are one of the most beautiful ways to enhance your hair, whether you want to add length, create fuller-looking volume, support a new shape, or introduce soft colour dimension without permanently changing your natural hair.
When applied well, extensions should never feel separate from your own hair. They should feel soft, discreet, and completely personal. The best extensions do not overpower your hair. They blend with it, move with it, and elevate what is already there.
As a Great Lengths x Rossano Ferretti Certified Expert at the Rossano Ferretti HairSpa inside Park Hyatt New York, I often meet clients who are excited about extensions but unsure how to care for them at home.
Hair extension aftercare should feel simple, but it does need to be consistent. At Rossano Ferretti, our approach to extensions is rooted in personalisation, artistry, and the health of the natural hair. This is why the brand’s partnership with Great Lengths feels so considered: it allows us to combine specialist extension expertise with the softness, movement, and harmony of the Ferretti Metodo Cut. I’ll talk more about this later in the article.
Below, I’ll share the professional advice I give in the salon, from brushing and washing to sleeping, styling, and maintenance, so your extensions stay soft, seamless, and natural-looking.
Understanding Your Extensions First
Before you begin caring for your extensions, it is important to understand which method has been used.
Different types of extensions sit differently in the hair. Keratin bonds, tapes, wefts, and other professional systems all have their own aftercare needs. Some are applied strand by strand, some sit flatter against the scalp, and some are designed to be removed and reapplied.
This matters because your routine should protect both the extension hair and the attachment points.
During a professional consultation, your Certified Extensions Specialist will study your natural hair carefully before recommending any extension service. They will look at your hair type, density, texture, scalp condition, colour, lifestyle, and styling habits.
For example, fine hair may need a lighter and more discreet application. Thicker hair may need more careful blending to create balance. Curly or wavy hair needs attention to texture, movement, and how the extensions will sit once styled.
This is why extensions are never one-size-fits-all. The most beautiful results are always personalised.
At Rossano Ferretti HairSpas, we approach extensions in the same way we approach the Ferretti Metodo Cut: by looking at the individual. The goal is not simply to add length or volume, but to create harmony.
Why Hair Extension Aftercare Matters
Even premium-quality extensions need the right routine to keep them feeling soft, smooth, and easy to manage. Just like your natural hair, they are affected by washing, styling, sun exposure, friction, and daily wear.
One important difference is that extension hair does not receive sebum, the natural oil produced by your scalp. Your natural hair benefits from these oils every day, especially near the roots. Extensions, however, need nourishment to be added through your routine so the mid-lengths and ends continue to feel soft, polished, and healthy-looking.
It is also important to remember that your natural hair is still living alongside the extensions. We replace the extension hair when needed, but we do not replace your own hair, so it needs to be cared for throughout the time you wear them. Good aftercare helps care for both: the quality of the extension hair and the comfort, condition, and movement of your natural hair underneath.
Good aftercare helps preserve:
- Softness
- Shine
- Natural movement
- Colour vibrancy
- A seamless blend
- Comfort at the roots
- The quality of the extension hair
- The health of your natural hair
I always tell clients that extension care does not need to feel complicated. It is about consistency. A few small habits, done well, can make a huge difference to how your hair looks and feels day to day.
How to Care for Hair Extensions at Home
1. Wash with Care
Before washing, brush your hair thoroughly to remove tangles. Wet hair is more fragile, so it is always better to detangle first.
In the shower, keep your head upright and allow the water to flow down the hair in its natural direction. Avoid flipping your head upside down, as this can encourage tangling near the roots.
Apply shampoo to the scalp and massage gently with your fingertips. Avoid using your nails or rough circular movements to prevent friction and damage. As you rinse, the shampoo will naturally move through the mid-lengths and ends, so there is no need to rub the lengths together.
My washing advice is simple: brush before washing, keep the hair flowing downwards, cleanse the scalp gently, avoid piling the hair on top of your head, and rinse thoroughly.
Rinsing is especially important. Shampoo, conditioner, or styling product left near the roots can create build-up and make the hair feel heavy or uncomfortable.
2. Brush Gently
Brushing is one of the most important steps in hair extension care. Gentle brushing helps prevent tangles, knots, and matting, especially around the nape of the neck and near the attachment points.
Brush according to your hair type and the guidance of your stylist. Hair extensions do need gentle detangling, but the right routine can vary depending on your hair texture, lifestyle and the type of extensions you wear. Your stylist can advise how often to brush and which tools are best for you.
It is natural to shed hair every day. On average, we lose around 100 to 150 strands daily. When you wear extensions, some of these shed hairs can become held by the attachment points rather than falling away naturally. If they are not brushed properly, they can begin to gather and mat close to the roots.
For the lengths and ends, always start low and slowly work your way up, holding the hair to avoid pulling on the attachment points. Once the hair is free of tangles, gently brush from the scalp, over the bonds, and down in the direction of the hair using an extension-safe brush. Never drag a brush through knots or pull through tangles, as this can create unnecessary tension.
I recommend doing this in sections, always on dry roots and dry attachment areas. Avoid brushing over the bonds when the roots or attachment sites are wet, as this can cause the shed hairs to compact and make removal more difficult later.
For Great Lengths extensions, use the Great Lengths brush, which has been specifically created for this purpose. It is designed to brush safely over the attachment areas while helping to keep the natural hair and extensions smooth, separated, and easy to manage.
As a guide, brush in the morning, at night, before shampooing, and after shampooing once the roots and attachment areas have been dried.
Pay particular attention to areas where friction happens, such as the nape of the neck, behind the ears, underneath the hair, and where scarves, coats, or collars touch the hair.

3. Keep the Lengths Nourished
Because extension hair does not receive natural oils from the scalp, moisture is essential.
Conditioner and masks can help keep the hair soft, smooth, and manageable, but they must be applied in the right place. Use richer formulas through the mid-lengths and ends, not directly on the attachment points unless your stylist has advised otherwise.
Think of it this way: the lengths need nourishment, while the roots and attachment areas need to stay clean and light.
After shampooing, apply your conditioner or mask from the mid-lengths to the ends. Smooth it through gently with your fingers or a wide-tooth comb, then rinse thoroughly after a few moments (or as advised on the bottle).
4. Dry Extensions Properly
After washing, gently squeeze out excess water and blot the hair with a soft towel or microfibre towel. Do not rub, twist, or rough-dry the lengths, as this can disturb the cuticle and encourage tangling.
Once towel-dried, detangle gently from the ends upwards. Then dry the roots and attachment areas first.
You should never sleep with wet hair extensions. Damp hair is more fragile, and when it moves against the pillow overnight, it can tangle or mat more easily.
When blow-drying, use controlled airflow and direct the dryer down the hair shaft. Medium heat is usually enough. Keep the dryer moving and finish by smoothing the mid-lengths and ends.
If you prefer to air-dry, speak to your stylist first. Some extension methods still require the root and attachment areas to be dried using heat.
5. Protect Your Hair While You Sleep
Night-time care can make a big difference to the condition of your extensions.
Before bed, brush your hair gently and tie it in a loose braid or low ponytail. Avoid tight styles that pull at the roots. The goal is simply to keep the hair contained while you sleep.
A silk or satin pillowcase can also help reduce friction and keep the hair smoother by morning.
Most importantly, never sleep with wet hair extensions. (I can’t stress this enough!).
6. Style with Heat Thoughtfully
You can usually curl, wave, or straighten hair extensions, but heat should always be used with care.
Before styling, apply heat protection through the lengths and ends. Avoid applying heavy formulas directly onto bonds, tapes, or attachment points unless your stylist has confirmed that it is suitable.
Keep hot tools away from the attachment areas, as direct heat can weaken some systems. You also do not need the highest heat setting. Extensions often style beautifully with controlled heat, good sectioning, and patience.
For the most seamless result, style your natural hair and extensions together so they move as one.
7. Prevent Tangling and Build-Up
Tangling is one of the most common concerns with hair extensions, but it is often preventable.
The most common causes are dryness, friction, product build-up, sleeping with wet hair, not brushing enough, and waiting too long between maintenance appointments.
If you feel a knot forming, do not pull through it. Hold the hair above the knot and gently work from the ends upwards. If the tangle is close to the attachment points, contact your stylist for advice. Gentle finger separation can help loosen a small knot before it develops into matting.
If you notice matting near the root or attachment area, this is usually a sign that the attachment site needs to be brushed more often and more carefully. Work in small sections and brush over the bonds in the direction of the hair, only when the roots and attachment areas are dry.
With products, less is often more. Too much oil, dry shampoo, hairspray, or leave-in product near the roots can make extensions feel heavy, sticky, dull, or difficult to brush. Focus styling products mainly on the mid-lengths and ends.
How Often Should You Wash Hair Extensions
For many clients, washing two to three times per week is enough, but this depends on your scalp, lifestyle, and extension method.
If your scalp becomes oily quickly, if you exercise frequently, or if you use styling products often, you may need to wash more regularly.
Over washing can make extensions feel dry, while under washing can allow oil and product build-up to collect near the roots. The best routine is balanced: cleanse when your scalp needs it, nourish the lengths, and avoid build-up to sit in the hair for too long.
If your roots feel oily between washes, a dry shampoo can help, but choose one that refreshes without leaving behind a talcy build-up. The Vivace Dry Shampoo Crème is a client-favourite as it has an innovative creamy texture that absorbs quickly, helping to refresh and volumise the roots instantly while keeping the lengths and attachment points feeling light.
Exercise, Swimming, and Holiday Care
Your lifestyle plays an important role in how you care for your extensions.
If you exercise regularly, tie your hair in a loose ponytail, braid, or low bun before you begin. The aim is to keep the hair secure without creating tension at the roots, so avoid anything too tight or pulled back. When your scalp becomes damp with sweat, give it time to dry properly, then brush gently afterwards to keep the lengths smooth and free from tangles.
Swimming requires extra care, not because you need to worry about the quality of Great Lengths extensions, but because any hair, natural or extended, benefits from being protected from repeated exposure to pool water, salt water, sun, and humidity. Before getting in the water, brush your hair and secure it in a braid to help reduce tangling.
If you are swimming in a pool, saturate your hair with fresh water first. This helps fill the hair cuticle with clean water, so it is less exposed to chlorinated water while you swim.
After swimming, rinse thoroughly with fresh water as soon as you can, then cleanse and condition as advised by your stylist. Avoid slicking the hair back while it is wet, and do not leave the attachment areas wet for longer than necessary. Leaving the hair down while it begins to dry can help avoid excess tension and reduce the risk of moisture sitting around the bonds.
On holiday, sun, humidity, heat, and UV exposure can all affect how extensions feel. Ask your stylist how to adapt your routine before you travel.
Thanks to Great Lengths’ unique colourisation process, clients can enjoy their summer routine with more confidence, with less concern about sunscreen transferring onto the hair and altering the shade. This is especially important for blonde extensions, which in some systems can be more vulnerable to pink or orange discolouration from certain sun filters such as Avobenzone.
Why Maintenance Appointments Matter
Professional maintenance is essential for keeping extensions beautiful and protecting your natural hair.
As your own hair grows, the attachment points move further away from the scalp. This changes how the extensions sit and can increase the risk of tangling if they are not maintained properly.
During a maintenance appointment, your stylist will check how the extensions are growing out, whether any sections need attention, and whether the hair needs reshaping or refining.
Maintenance is not just practical. It is part of keeping the final result soft, blended, and natural-looking.
How often you need maintenance depends on your extension method, natural hair growth, and lifestyle. Your stylist will advise the right schedule for you.
