How to Use Hair Conditioner, Deep Conditioner & Leave-In Conditioner

For a regular hair conditioner, apply from mid-lengths to ends after shampooing, leave for 2–3 minutes and rinse thoroughly — avoid applying to the roots if you have fine or oily hair. For a deep conditioner or hair mask for dry hair, apply generously after shampooing, comb through and leave for a minimum of 5–10 minutes (or up to 30 minutes under a shower cap for intensive treatment) before rinsing. The Olaplex No.8 Bond Intense Moisture Mask can be left on for up to 10 minutes for maximum bond repair and moisture. For a leave-in conditioner, apply to towel-dried hair before styling — the Color Wow Money Mist and Sol de Janeiro Brazilian Joia Milky Leave-In are both ideal as a leave-in conditioner spray for daily use.
