It's a common question: When does my beard grow full? Well, the short answer is that nobody knows for sure. Beard growth is tied to genetics more than anything else, so the best way to predict when your beard will be fully grown is to look at old man. If you're lucky enough to have an older brother or father who has a thick and healthy beard, then you can expect that same kind of growth pattern in yourself as well. However, there are some things you can do now which can help speed up the process along as well!
Beard growth is tied to genetics more than anything, so the best way to predict when your beard will be fully grown is to look at your old man.
The answer is that the time it takes for your beard to grow depends on genetics, and the number one factor in determining this is family history. If you're a man and want to know when your facial hair will be fully grown, look at your father and grandfathers--and great-grandfathers if you can find pictures of them--and see how long their beards were at each stage of life.
If they all had full beards by age 30 or so (and most do), then it's probably safe to say yours will too; if not, then don't worry! You'll likely end up somewhere between them when it comes time for yours to come in fully grown. As far as average growth rates go: 2 months for stubble; 4 months for light stubble/spots where facial hair starts showing up but isn't yet thick enough that people would notice unless they were very close; 6 months until there's enough density throughout those spots that even strangers would think twice before asking "Doesn't he shave?"
Take a good look at the males in your family and you should get a decent idea of how long it will take for you to grow a full beard that is thick and healthy.
In order to find out how long it will take you to grow a full beard, you should take a good look at the males in your family and see how they have been doing. If you have any uncles or brothers who have facial hair, pay attention to what kind of beards they have and how long they've had them for. You can also look at older male members of your family such as grandfathers or even fathers if they have been able to keep their beards well groomed and trimmed over time.
Be patient -- it will happen.
Be patient. It is a virtue, after all. You can't rush the process; if you try to grow a beard before your body is ready for it, you may experience ingrown hairs and other problems. The good news is that most men reach their full facial hair potential at about age 21 or 22 -- but some don't hit their stride until they're 25 or even older!
If you're still in high school or college and want to make sure your beard grows in properly (and not just patchy), consider waiting until after graduation before attempting any serious shaving habits.
The average man takes 2 to 4 months to grow a full, even beard. You can help your beard grow faster and thicker by eating more B vitamins, taking biotin supplements and drinking more water.
A lot of factors affect the growth rate of your beard, but if you're in your teens or early 20s and are just starting to grow out your facial hair, it's likely that you'll be able to see some results by the time summer rolls around.
If you're older than that and haven't had much success growing a full beard yet (or at all), don't worry about it too much. There are plenty of things that could be affecting how quickly or slowly your facial hair grows: genetics play a huge role in determining how thick or thin your mane will be; stress can slow down hair growth; poor diet may also limit the amount of nutrients available for growing healthy facial hair. And finally--and this is important--certain medications like antidepressants can have an impact on hormone levels which might affect how well they work with each other throughout puberty into adulthood.*
Beard growth is a very personal thing and it can take some time, but with the right tools and attitude, you will get there.
