Jackal... you say you noticed a colour-difference when the sun was shining on the hair.. in what way is it different to your growing hair....is it a darker or lighter tone ? Sometimes the wave can be a bit tricky... my systems always have bodywave, but it can vary in `intensity` from one system to another...these things are individually made and no 2 will be exactly the same, particularly if a few months passes between orders....if you get ,say, 2 systems together at the same time, most likely they will be very alike, but on the next order, it may be `off` compared to the earlier order... certainly sounds like there is a crown on that system...always check it out when it first arrives and if you feel there is an issue, raise it with John rather than doing anything to the system such as cut-in/styling... usually these things are pretty much as ordered but there are times when things can be `off`.
