YouthLock is Joico's first collagen-infused permanent creme color, built for 100% gray coverage. It mixes 1:1 with 20 vol LumiShine Developer and processes 35 to 45 minutes at room temperature. Every shade sits in the Natural Natural family, written with a double N: NN, NNA for natural with ash, NNG for natural with gold, NNW for natural warm and NNWC for natural warm copper. The NN shades are made with extra opacity. Like the rest of LumiShine, each code also has a decimal version, such as 6NNG and 6.003.
