What It Does

Keep your hair fresh, smooth and healthy-looking between washes with the K18 Routine Collection – No-Wash Day. This three-step routine refreshes the scalp, repairs and strengthens damaged hair, and smooths frizz and flyaways without weighing hair down. Finish with daily FutureIQ™ scalp care to support healthier-looking hair and scalp over time.

Your ultimate K18 routine for between wash days.

Extend your good hair days with the K18 Routine Collection – No-Wash Day, a targeted three-step routine designed to refresh your hair, smooth frizz and support stronger, healthier-looking hair and scalp between washes.

Start with AirWash™ dry shampoo, a non-aerosol formula that absorbs excess oil and sweat while neutralising odour, leaving hair fresh, soft and touchable. Its translucent microbeads help absorb oil without visible residue or a white cast, making it ideal for refreshing hair between washes.

Next, apply K18 Molecular Repair Hair Oil to damp or dry hair. This weightless, silicone-free oil is powered by K18PEPTIDE™ and nourishing oils to address damage that contributes to frizz while smoothing the hair surface, enhancing shine and helping protect against heat up to 450°F / 232°C.

Complete your routine with FutureIQ™ biomimetic hair longevity serum, a lightweight daily scalp treatment powered by MultiVital™ technology. Used nightly, it is designed to help reduce shedding, reduce the appearance of greying and support scalp longevity.

Three products. One easy routine. More good hair days — without washing your hair.

Usage & Ingredients

How to Use K18 Routine Collection – No-Wash Day


STEP 1 — REFRESH

AirWash™ Dry Shampoo

Shake well for at least 5 seconds. Hold 10–15cm from the scalp, section hair and apply approximately one spray per section. Massage into the scalp, then brush or style as usual. Use between washes whenever hair needs a refresh.

STEP 2 — SMOOTH & REPAIR

Molecular Repair Hair Oil

For damp hair, apply 1–3 drops from mid-lengths to ends. For the K18PEPTIDE™ strengthening benefits, wait 4 minutes before styling.

For dry hair, apply 1–3 drops as a finishing treatment to smooth frizz and flyaways and enhance shine. Build gradually as needed.

STEP 3 — SUPPORT SCALP LONGEVITY

FutureIQ™ Serum

Use once nightly on a damp or dry scalp. Apply 4 droppers filled to the line, distributing across the middle part, side part and hairline. Massage evenly from the hairline towards the crown and nape until absorbed. Do not rinse.

No-Wash Day Tip: Use AirWash™ whenever your scalp needs refreshing, Molecular Repair Hair Oil whenever your lengths need smoothing, and FutureIQ™ every night as part of your ongoing scalp routine.
