K18 Mask was not formulated to work like a regular conditioner. Although some find it provides adequate softening and smoothing properties, others may prefer enhanced conditioning benefits by adding a leave-in conditioner after the four-minute processing time. On the days that you are not using K18 Mask, use your regular in-shower or leave-in conditioner as usual. If heat styling, use a heat protectant after the four-minute processing time. You may also layer additional styling products on top of the mask if needed.
