The best way to care for hair extensions is to wash them gently with sulfate-free products, brush them carefully with an extension-friendly brush, avoid sleeping with wet hair and follow the right daily routine.
Hair extensions can look beautiful for months, but only if they are cared for properly. Whether you wear tape-in extensions or clip-in extensions, daily care makes a big difference in how natural they look, how soft they feel and how long they last.
At BRUSH Amsterdam, we work exclusively with 100% premium Remy human hair and specialise in our natural hair extensions services that blend the extensions seamlessly with your natural hair. To keep them in top condition, the right homecare routine is essential.

How to wash hair extensions
Hair extensions should always be washed gently to protect both the extension hair and the attachment points.
- Use a sulfate-free, gentle shampoo
- Massage the scalp carefully without rubbing the extensions together
- Rinse thoroughly with lukewarm water
- Apply conditioner only to the mid-lengths and ends
- Avoid conditioner directly on tapes, bonds or clips
- Do not wash the hair upside down, as this can cause tangling
Washing too aggressively can shorten the lifespan of extensions and create unnecessary stress around the roots.
How often should you wash hair extensions?
In most cases, 2 to 3 washes per week is enough.
Washing too often can dry out the lengths and ends, while washing too little can lead to buildup around the roots. The right balance depends on your hair type, lifestyle and how many styling products you use.
How to brush hair extensions properly
Brushing your extensions the right way helps prevent tangling, matting and unnecessary tension.
- Use an extension-friendly brush such as the MANE MAVEN ZigZag Brush
- Start at the ends and work upward gradually
- Hold the roots gently while brushing to avoid pulling on the attachments
- Brush 2 to 3 times per day
- Always brush before showering and before bed
Do not brush aggressively and never tug through knots. Gentle detangling is essential if you want your extensions to stay smooth and natural-looking.
Can you brush hair extensions when wet?
It is best to avoid brushing extensions when they are very wet.
Wet hair is more elastic and more vulnerable to breakage. If needed, first let the hair dry partially and then detangle gently from the ends upward with the right brush.
How to dry hair extensions
After washing, gently squeeze out excess water with a towel. Do not rub the hair dry.
- Pat or squeeze gently with a soft towel
- Let the lengths air dry partially if possible
- Always dry the roots properly, especially with tape-in extensions
- Use heat protection before blow-drying
Leaving the attachment area damp for too long can affect both comfort and longevity.
How to sleep with hair extensions
You should never sleep with loose, wet or tangled extensions.
- Brush the hair before bed
- Tie it into a loose braid or low ponytail
- Use a silk pillowcase to reduce friction
- Make sure the hair is fully dry before sleeping
This helps prevent tangling, dryness and unnecessary pulling while you sleep.

What products should you use on hair extensions?
The best products for hair extensions are nourishing, lightweight and sulfate-free.
At BRUSH, we often recommend:
Lightweight oils and shine products can keep the ends soft and polished, but they should be kept away from the attachment points.
What should you avoid with hair extensions?
To keep your extensions in the best condition, avoid the following:
- Sleeping with wet hair
- Applying conditioner or oils directly on tapes or bonds
- Using harsh shampoos with sulfates
- Excessive heat without protection
- Rough brushing or pulling through knots
- Skipping maintenance appointments
How to keep hair extensions looking natural for longer
The most natural result comes from a combination of proper homecare and professional maintenance.
Daily care keeps the hair soft and manageable, while salon maintenance keeps the placement clean, comfortable and beautifully blended. That is especially important if you wear tape-ins on a daily basis.
