Human hair extensions can give you longer, fuller and glossier hair, but they need the right care to stay soft and beautiful. Because extensions don't receive natural oils from the scalp, they need extra moisture, protection and gentle handling.

With the right routine, you can avoid dryness, tangles and unnecessary wear.

Why do hair extensions need extra care?

Human hair extensions behave like your own hair, but they dry out more easily because they get no nourishment from the scalp.

That's why moisturising products, gentle brushing and heat protection are especially important.

Brushing your extensions the right way

Always brush gently and start at the ends. Then work your way up a little at a time.

Use a brush for hair extensions and hold the hair near the bonds so you don't pull on your own hair.

How to wash hair extensions

Don't wash your extensions more often than necessary. Use lukewarm water and a mild, moisturising shampoo – you'll find our recommendations in hair care for extensions.

Apply conditioner to the lengths and ends, but avoid putting conditioner, oil or hair masks directly on bonds such as tape or keratin.

Use moisture and heat protection

Extensions need moisture to stay soft and shiny. Use conditioner, a hair mask when needed and a little hair oil on dry ends.

If you use a flat iron, curling iron, hairdryer or hot brush, always use a heat protectant and preferably a low to medium heat setting.

Sleeping with hair extensions

Never sleep with wet hair. Brush your hair gently before bed and put it in a loose braid or a low ponytail.

A silk pillowcase can also reduce friction and help your hair stay nicer for longer.

Care for different types of extensions

Tape-in extensions: Avoid oil and conditioner near the tape bonds.

Hair weft and weave: Keep your scalp clean and make sure the hair dries thoroughly.

Clip-on extensions: Always take them out before you sleep and store them dry and protected.

Hair topper: Brush gently, don't wash too often, and store it on a stand or in a bag.

Common mistakes to avoid

Avoid brushing too hard, sleeping with wet hair, using too much heat or skipping heat protection.

Also, don't wash your hair too often, and avoid harsh or drying products.
