How does this fi t into the K18 routine?

For best results, use TripleBright weekly for brighter, longer-lasting blonde. Pair with the molecular repair mask to keep hair soft, strong, and bouncy after bleach damage. 

You can use any K18 styling products, molecular repair hair oil, AstroLift™ reparative volume spray, AirWash™ dry shampoo, and HeatBounce conditioning heat protectant, as usual after the mask. Between TripleBright + mask days, use K18 damage shield shampoo + conditioner to maintain healthy hair.
