K18 Site →Amazon →SUMMARY OF REVIEWS
K18 AirWash Dry Shampoo is a liquid formula that sprays on wet and dries to a powder-like finish, effectively absorbing oil without leaving a white cast on most hair colors. Board-certified dermatologist Dr. Sam Ellis rates it 9.5/10 for oil absorption, noting it can leave a bit of white residue on dark surfaces. A few creators mention it can feel heavy the next day, requiring a wash, but most praise its lightweight volume and ability to extend hairstyles for days.
