Stocks come in a medium density sopo.... John might have a lighter brown which MAY work for you.... colour 1b is a very dark brown,[and available on stocks] one step up from black, but the fact that you have slightly reddish hairs scattered in your growing hair might be tricky to work with....... if you go custom, they`ll be able to do a better match both from your hair sample and if possible send in a few really sharply-focussed pics [ under good natural light] and it will also help.....would you consider using a bit of colouring product on your own to tone down the reddish hue? That way you could easily get away with getting a stock and cutting it to suit..would be faster anyway. Just a thought......
