Apply after shampooing. Squeeze hair to remove excess moisture, then apply to wet hair. Use fingers (or a wide tooth comb) to work product through to ends. How much you use depends on the length, thickness and health/condition of your hair. Start with one “finger scoop” and apply enough to cover hair from roots to ends. Apply more product as needed. Leave mask on hair for 3 to 5 minutes in the shower, or up to 20-30 for a deep treatment. (There is no problem if you leave the mask on longer- it will auto-stop when your hair strands have reached the saturation point.) There is no need to shampoo after using, simply rinse hair thoroughly. Money Masque benefits and effects last for days and through several shampoos. We recommend using it every 3rd shampoo.
