Longevity varies by hair type and maintenance, but many clients enjoy improved strength and softness for several weeks. Continued homecare and professional touch-ups help maintain and prolong the visible results.

In many cases yes; our team can integrate K18 with color, cut, or smoothing services. We will sequence treatments to prioritize hair health and optimal results—consult your stylist during booking for personalized planning.

We recommend using gentle, sulfate-free shampoos and a low-residue product routine. Your stylist can suggest specific maintenance products—including K18 at-home options—to support ongoing repair and extend treatment benefits.
