- Apply Luster Lock to damp, freshly shampooed hair from scalp to ends. Time for up to 5 minutes, then rinse thoroughly with warm water.
IN THE SALON
Luster Lock makes a perfect add-on service in the salon. Offer your color clients a Luster Lock treatment at the backbar while they’re getting their color service for instant softness, shine, manageability and color vibrancy, then send them home with a tube for stronger, healthier hair with every use.
Following color processing (according to manufacturer directions) and thoroughly rinsing hair:
Apply Luster Lock to damp hair and leave in for up to 5 minutes. Rinse hair thoroughly with warm water.
Another great way to use Luster Lock is on dry hair as a “pre-shampoo” treatment!!!
Apply between foils or to hair lengths while base color is processing, then shampoo out with hair color.
