Mask: after shampooing, apply on towel-dried hair over the whole length from the roots to the ends and leave on for 5-10 minutes before rinsing. Pack: apply on dry hair and leave for at least 15 minutes before shampooing. Another idea? For a periodic 'shock' treatment, apply on dry hair and cover with a hair cap to boost the results with a 'heat effect' and leave for at least an hour before shampooing.
