Stocks are a medium density anyway, so if you want to ` experiment` with a stock, I reckon , looking at your hair, it will match..... you could take a hair sample and send it in to John to get the nearest colour in a stock rather than try to ` guess` it from the order form......you`re not in a hurry, so a few days ` wait` won`t hurt. I agree with the assertion that simply allowing your hair to grow a bit more will help---it`s still a little early for you to be wearing as such.... but I know where you`re coming from in your thinking and you want to start ` experimenting`... take your sample from the front part of the head as the back of the head tends to grow darker hair.... so as it`s the front area you want to work-on, the hair there will be a bit lighter , so take your sample from there.
