Let sit for 4 minutes. Do not rinse out.

Then comb + style as usual (fine to add heat protectant or styling product now).

Use for the first 4-6 washes, then as needed

DO clarify before K18 if you’re a heavy product user (demineralize for mineral + metal buildup)

DO apply on clean, damp hair

DO wait the full 4 minutes before combing or styling

DO add whatever styling products you love after the 4 minutes

DO use for 4-6 shampoos consecutively for progressive results.

DON'T use conditioner before applying K18 Mask (you can apply after the 4 min but most find they don’t need it)
