I've got a 10'' naturally jet-black colored beard. I decided to dye it medium brown for various reasons, and I did. Now, the problem is - the uncolored roots of the uppermost hairs of my beard show up as the beard gets longer. Given that the beard will be kept at the length of 10'', is there any way to get rid of this problem? I figured, if I can slow down (or even stop?) the rate at which my beard grows, it should solve the problem. What do you think? And please, don't answer anything like "keep the beard jet-black, etc".
