As far as I can remember, he ordered a stock [he can clarify that himself] but just to say that Back2natural can be used any time to help mask minor color-blending issues no matter if the system is relatively new....it also won`t stain lace to any severe degree if it gets onto it. It`s a conditioner too, so is good / `kind`to hair, in contrast with other [chemical-based] coloring products. Stock hair can be `off`in terms of color-match ---the best way to [hopefully !] get as good a match as possible, is to order custom-made and send in a sample of your growing hair. Back2natural has it`limitations ` as it`s an organic product.....if the hair needs a fairly deeper color, well then chemical-based solutions are the best but they can be harsh on the hair. Paul.
