Frequently Asked Questions
This 2-piece travel-ready duo includes:
- K18 Leave-In Molecular Repair Hair Mask (50ml): A 4-minute treatment that repairs hair damage caused by bleach, color, chemical services, and heat styling.
- K18 AirWash Dry Shampoo (47ml): A non-aerosol liquid dry shampoo that absorbs oil, eliminates odor-causing molecules, and keeps hair feeling clean between wash days.
Use them on different days depending on whether it is a wash day or non-wash day:
On Wash Day (K18 Mask): Shampoo hair, skip conditioner, and towel-dry thoroughly. Apply 1–3 pumps of mask, distribute evenly, and wait 4 full minutes. Do not rinse out. Style as usual.
On Non-Wash Days (AirWash): Shake well for 5 seconds. Hold bottle 4–6 inches away from dry hair, spray 1 pump per section at the roots, massage in, and brush through to absorb oil and refresh style.
Yes. Both containers (50ml mask and 47ml dry shampoo) are well under the 100ml (3.4 fl oz) liquid restriction, making the set 100% TSA-compliant for airport carry-on bags.
Because K18 formulas are highly concentrated:
- The 50ml Mask delivers approximately 35 to 50 applications (1 to 2 months of regular repair treatments).
- The 47ml AirWash Dry Shampoo yields up to 30+ applications for extending blowouts and styles between washes.
It is ideal for anyone with damaged, bleached, color-treated, or heat-styled hair who needs structural repair on wash days and an oil-absorbing, odor-eliminating dry shampoo on non-wash days. Safe for all hair types and textures—fine, medium, coarse, straight, wavy, curly, and coily.
No. AirWash uses translucent microbeads and odor-eliminating technology instead of white powdery starches or harsh gases. It absorbs oil invisibly without leaving a powdery residue, making it ideal for dark hair and compatible with hair previously treated with the K18 Mask.
