Lifestyle - There are many aspects of your lifestyle that can positively or negatively impact how long it takes you to grow a beard. The heathier you are, the faster your beard will grow.  This includes things like a well balanced diet, getting enough exercise, drinking enough water, lowering your stress, and taking the proper supplements.  A few key supplements that help with beard growth would be biotin and collagen.  

Areas of Growth - With talking about beard growth in general we want to keep in mind that each part of the beard grows differently. Generally the fastest and longest growing areas would be along the jawline and chin area. The more north or south you go from there will almost always result in slower and shorter growth. Your cheek hairs will likely be your shortest and slowest. This is one thing to keep in mind when planning out the best style for you.

Now sit back and enjoy that luscious man mane of yours, while you look and smell great!
