We are now offering our 1oz packets of our Pretreatment, which prepares the hair for Hairprint by putting it into an alkaline state. If you need to split up a kit for root/touch up treatments or have very thick/long hair, we strongly recommend getting extra pretreatment packets to ensure optimal results. One (1) pretreatment packet is included in each Hairprint Kit.**NOT TO BE USED IN PLACE OF OUR DETOX SHAMPOO**
