How to wash and dry hair extensions
Extensions don't get natural oils from your scalp, so they need far less washing than your own hair. Washing them gently and rarely is the biggest thing you can do to make a set last.

Washing clip-in extensions
- Detangle first with a loop or wide-tooth brush, working from the ends up.
- Fill a basin with lukewarm water and a small amount of sulphate-free shampoo. Lay the wefts in and gently swish. Don't rub or scrunch.
- Rinse under a gentle stream, keeping the hair pointing downwards.
- Apply conditioner to the lengths and ends only, never on the wefts or clips, then rinse.
- Press the water out with a towel. Don't wring.
Washing tape-in and other fitted extensions
- Use sulphate-free, moisturising products and keep conditioner away from the bonds.
- Shampoo with your head upright, working downwards. Avoid piling hair on top of your head, which can tangle it.
- Don't sleep with wet hair. Dry the roots fully so the bonds don't weaken.
Drying
Lay clip-ins flat or hang them over a towel rail to air dry. Keep them away from direct sun and radiators. Brush once fully dry. If you use heat, use a protectant and a moderate setting.
Storing between wears
Once dry, store flat in a box or hang on a hanger designed for extensions. Avoid tossing them loose in a bag, where they tangle and shed.

Frequently asked questions
How often should I wash clip-in extensions?
Only when needed, often every 15 to 30 wears depending on how much product you use. Because they don't get scalp oils, over-washing dries them out.
Can I wash tape-in extensions the same day they are fitted?
Follow your stylist's advice. Many recommend waiting 48 hours so the tape can bond fully.
Can I blow dry extensions on high heat?
It's best to use a medium setting and a heat protectant. High heat can damage extensions, especially human-hair sets with a coating.
