Clip-in hair extensions don’t need to be washed after every wear. Washing them only when needed, then handling them gently as they dry, can help keep your routine simple and your set ready for another good hair day.
Here’s how to wash clip-in hair extensions at home, step by step. Always check the care instructions for your specific set before you begin.
How often should you wash clip-in hair extensions?
Wash clip-in extensions when they have noticeable product buildup, feel less fresh, or need a proper refresh—not automatically after every wear. Frequent washing can add unnecessary handling to your care routine, so start by brushing out tangles and decide whether a wash is actually needed.

What you’ll need
Before you start, gather:
- A clean basin or sink
- Cool or lukewarm water
- A gentle, extension-friendly shampoo
- A lightweight conditioner
- A clean microfiber towel or soft towel
- A clean, flat place for air-drying
Use products that are suitable for your extensions. Avoid heavy oils and rich conditioner near the weft base and clips. OLIS product care information recommends gentle, extension-friendly products; check the instructions for your exact set before washing. CLIP-IN HAIR EXTENSIONS – OLIS Hair
How to wash clip-in hair extensions at home
1. Remove the extensions and detangle them

Take out each weft before washing. Close the clips, then gently detangle from the ends upward while supporting the weft with one hand. Work through any knots slowly rather than brushing forcefully.
2. Wet the hair gently
Fill a clean basin with cool or lukewarm water. Hold the weft by its base and let the lengths become wet. Move the hair through the water gently; avoid twisting or bunching it together.
3. Shampoo with a light touch

Use a small amount of gentle, extension-friendly shampoo. Smooth it down the lengths in one direction with your fingers. Avoid scrubbing, rubbing the hair together, or working shampoo aggressively into the base and clips.
If the lengths still feel coated, rinse and repeat gently rather than using a stronger cleanser.
4. Rinse thoroughly
Rinse the weft in cool or lukewarm water until the shampoo is gone. Keep the hair flowing in the same direction as you rinse, and support the base so the lengths don’t tangle.
5. Apply conditioner to the lengths
Apply a small amount of lightweight conditioner through the mid-lengths and ends. Keep it away from the base and clips, then rinse thoroughly. A light hand helps avoid leaving the hair feeling weighed down.
6. Blot out excess water

Lay the hair on a clean towel and gently blot it. Don’t wring, twist, or rub the lengths. OLIS care instructions for clip-in hair pieces also recommend blotting gently and allowing the hair to air-dry. OLIS Hair
7. Air-dry completely before storing
Lay the weft flat on a clean, dry towel or drying surface, keeping the lengths smooth and separated. Let it dry completely before storing or styling. Avoid putting damp extensions away, and follow the drying instructions for your particular set.
When the hair is fully dry, detangle gently from the ends upward and store it flat or on an extension hanger in a cool, dry place. The OLIS Almond Brown #5 Clip-In product page includes care guidance for that set, including washing only when needed and allowing it to air-dry completely before storage.

What to avoid when washing clip-in extensions
A gentle wash is easier when you avoid a few common habits:
- Don’t wash the set after every wear if it doesn’t need it.
- Don’t use hot water or scrub the lengths roughly.
- Don’t rub the hair into a ball or twist it to remove water.
- Don’t apply heavy oils or conditioner directly to the weft base and clips.
- Don’t store the extensions before they’re completely dry.
Can you blow-dry clip-in hair extensions?
Air-drying is a simple option for routine care. If your specific set’s instructions allow heat styling, use heat protectant and the lowest effective temperature. Avoid applying heat when the hair is wet or leaving it unattended near a heat source. Check the care instructions for your product before using hot tools.
