How to Wash Hair Extensions: A Step by Step Guide for All Methods

The most important rule before anything else

Before washing any type of bonded hair extensions, always use sulphate-free shampoo. Sulphates are the cleaning agents in standard shampoos that create lather. They are highly effective at removing oils but they also dissolve adhesive bonds and strip the natural cuticle from extension hair. Switching to sulphate-free shampoo is the single most impactful change you can make for extension lifespan — more important than any other product or technique.

How to wash tape hair extensions

Tape hair extensions require the most careful washing technique because the adhesive bond is vulnerable to products and water getting trapped between the tape pieces.

1. Brush hair gently from ends upward before getting in the shower to remove any tangles
2. Wet hair thoroughly with lukewarm water — never hot, which can soften the adhesive
3. Apply sulphate-free shampoo to the scalp and roots only, working in a downward motion
4. Allow shampoo to rinse through the lengths naturally — do not pile hair on top of head or scrub the extension area
5. Rinse thoroughly with lukewarm water until all shampoo is removed
6. Apply conditioner from mid-length to ends only — never near the tape bond area
7. Leave conditioner for 2 to 3 minutes then rinse thoroughly
8. Gently squeeze excess water from hair — never wring or twist
9. Pat dry with a microfibre towel from roots downward
10. Allow to dry thoroughly before sleeping or tying hair up

How to wash nano tip and I-tip extensions

Nano hair extensions and I-tip extensions are the most forgiving to wash because the ring attachment is not affected by water or shampoo. The main risk is tangling during washing.

1. Brush from ends upward before washing
2. Wet hair thoroughly with lukewarm water
3. Apply sulphate-free shampoo to scalp and roots, working gently in a downward direction
4. Rinse thoroughly
5. Apply conditioner from mid-length to ends, keeping it away from the ring attachment area at roots
6. Rinse thoroughly
7. Squeeze excess water gently — never wring
8. Brush gently while damp, starting from ends upward
9. Dry thoroughly before bed

How to wash weft and sew-in extensions

Weft hair extensions in a sew-in application require the most careful drying rather than the most careful washing. The braid base underneath the weft must dry completely after every wash to prevent scalp irritation and odour.

1. Brush extension hair gently before washing
2. Apply sulphate-free shampoo directly to the scalp through the parting between weft rows using fingertips
3. Work shampoo gently along the scalp — do not scrub the braid base aggressively
4. Rinse thoroughly, ensuring shampoo is fully removed from the scalp area
5. Apply conditioner to the extension lengths from mid-length to ends
6. Rinse thoroughly
7. Use a hooded dryer or diffuser to dry the braid base completely — this step is critical
8. Allow extension lengths to air dry or blow dry on a low heat setting

How to wash clip-in extensions

Clip-in extensions are washed differently from all other methods because they are removed from the head first.

1. Remove all clip-in wefts and detangle gently with a soft brush
2. Fill a basin with lukewarm water and a small amount of sulphate-free shampoo
3. Submerge the extensions and gently work shampoo through from root to tip in one direction
4. Rinse thoroughly with clean lukewarm water
5. Apply conditioner from mid-length to ends, leave 2 to 3 minutes, then rinse
6. Gently squeeze out excess water
7. Lay flat on a clean towel to air dry — never hang or use a tumble dryer
8. Store flat once completely dry
