How to Care for Your Clip-In Extensions

To keep your Seamless clip-in extensions looking beautiful, soft, and shiny for as long as possible, gentle care is key.

Brush them before and after each wear with a wide-tooth brush or a soft-bristle brush. When washing is needed, use a gentle sulfate-free shampoo and avoid rubbing the hair fiber too harshly. Rinse thoroughly, then apply a nourishing treatment to keep the lengths supple and smooth.

To make them last even longer, follow our care tips for natural hair extensions.

After washing, let your extensions air-dry whenever possible. You can also use a blow dryer on a low-heat setting. If you use a flat iron, curling iron, or any other hot tool, never go above 350°F and always apply a heat protectant before styling.
