Blog: How Long Does It Take to Grow a Beard? What Happens Week by Week
Most men can grow a full short beard in about twelve weeks. Facial hair grows roughly half an inch a month, so four weeks gets you something with a shape and six months gets you around three inches.
The hard part isn't the waiting. It's weeks two and three, when it looks worse than it did clean-shaven.
TLDR
• It grows about half an inch a month. There is no way to speed that up.
• Weeks 2 to 3 are the worst it will look. Uneven, itchy, and not yet long enough to read as deliberate. Almost everyone who quits, quits here.
• First shaping is at four weeks, not before. There's no shape to define until then.
• Patchy at three weeks means nothing. Different follicles start at different times, and slower areas get covered by longer hair from nearby.
• Shave your neck from day one. It's the whole difference between growing a beard and not having shaved.
Hair grows in cycles, and yours aren't synchronized
A hair follicle moves through three phases. Anagen is active growth, and for beard hair it runs for years. Catagen is a short transition of a couple of weeks where growth stops. Telogen is rest, after which the hair sheds and the follicle starts again.
At any moment the follicles on your face are scattered across all three. That explains the most common worry about growing a beard: it isn't coming in evenly. It was never going to. The hairs in anagen are growing now, and the ones in telogen will start later.
Which is why three weeks is too early to conclude anything about patchiness. You're looking at a partial roll call.
What actually happens, week by week
INSERT CHART
Those lengths assume about half an inch a month. That rate comes from a British Journal of Dermatology study that measured pigmented beard hair at 0.47 mm a day, which works out to just over half an inch a month. It tracked three men, so read it as a guide rather than a promise. Yours may run faster or slower, and that's genetics rather than anything you're doing right or wrong.
Week two is the one that beats people
It looks worse at two weeks than it did clean-shaven. That's normal and it's temporary.
Two things are happening at once. The hair is long enough to look untidy but too short to hold any shape, so it reads as neglect rather than intent. And it itches, because hair you've been cutting has a blunt cut end, and as it grows out those ends press against the skin around them. Once the hairs get longer and soften, the itch goes.
The only thing to do about week two is get through it. If the itch is bad, wash the beard and the skin underneath and keep the skin moisturized. The AAD's beard guidance covers dry itchy skin, beard dandruff and breakouts under a beard, which are the three things most likely to turn up in the first month.
What will not help: trimming it to tidy it up. At two weeks there's nothing to trim toward, and taking length off resets you.
Patchy at three weeks is not patchy
Slower areas are usually a timing problem, not an absence problem. Follicles that were in their resting phase when you started will come in later, and by the time the faster areas are an inch long they're covering a lot of what looked bare at three weeks.
The AAD's own advice for sparse growth is exactly this: let your beard grow, and fill patchy areas with longer hairs from nearby. They also note that some men use minoxidil for this, and that it's worth talking to a dermatologist first, because it can irritate the skin on your face.
If it's still bare at eight weeks, that's information. Then it's a question of picking a style that works with what grows, which the beard styles guide covers by face shape.
Shave your neck from day one
This is the single highest-return thing in the first month.
An unshaved neck is what makes early growth read as "hasn't shaved" rather than "growing a beard." Clearing it costs two minutes and changes how the whole thing looks weeks before there's a beard to look at. Week one is mostly five o'clock shadow that didn't get shaved off, and the neck is where it reads worst.
Your eventual neckline sits just above the Adam's apple, not along the jaw. For now, shave everything below a line a little lower than that. You don't have to commit to the final line yet, and going low leaves you room to set it properly at four weeks.
Soften the hair with warm water first and shave with the grain. The neck is where razor bumps are most likely, and our razor bumps guide covers what to do if they show up. Everything else stays untouched. No cheek line, no trimming, no tidying.
Four weeks is when you start shaping
At four weeks you have enough length that the beard has an outline, and that's the moment to set the neckline and the cheek line for the first time. How to do both is in shaving around a beard.
Do the neckline first. It's the one with the biggest effect and the clearest rule.
Things that do not make a beard grow faster
Short list, and worth saying because the internet is full of the opposite.
• Shaving. It doesn't change the rate or the thickness. Regrowth feels coarser because of the blunt cut end, not the hair itself.
• Trimming the ends. That's scalp-hair advice, and it doesn't work there either. Growth happens at the follicle.
• Beard oil. It conditions the hair and the skin under it, which makes a beard look and feel better. It isn't a growth product.
• Growth serums and balms. Nothing sold as a grooming product changes the growth rate. The one exception people point to is minoxidil, which is a drug, not a grooming product, and belongs in a conversation with a dermatologist.
What you can influence is whether you keep it long enough to find out what it does. That's most of it.
FAQ
How long does it take to grow a full beard? About twelve weeks for a full short beard, at roughly half an inch a month. Four weeks gets you a short beard with a shape. Six months gets you around three inches, which is where beards start needing combing and conditioning rather than just trimming.
Why does my beard look patchy? Because your follicles aren't synchronized. Some are in their growing phase and some are resting, so they don't all arrive at once. Patchiness at three weeks usually fills in by eight as longer hair from nearby covers it.
Why does growing a beard itch so much? Hair you've been shaving has a blunt cut end, and as it grows out those ends press against the surrounding skin. It fades once the hairs are long enough to soften and lie down. Washing the beard and moisturizing the skin underneath helps in the meantime.
When should I first trim a new beard? Four weeks. Before that there's no shape to trim toward, and taking length off just resets the clock. At four weeks, set the neckline first, then the cheek line.
Should I shave my neck while growing a beard? Yes, from the first week. It's the difference between looking like you're growing a beard and looking like you haven't shaved. Keep the line low early on so you have room to set it properly at four weeks.
Does shaving make your beard grow back thicker? No. Shaving doesn't reach the follicle, which is where growth is decided. The regrowth feels coarser because a cut hair has a blunt end instead of a tapered one. That's a texture change, not a growth change.
How fast does facial hair grow? Around half an inch a month for most men. One British Journal of Dermatology study measured pigmented beard hair at 0.47 mm a day. Rate varies between people far more than it varies based on anything you do.
What week do most people give up? Two to three. It's the point where the beard looks its worst, long enough to be untidy and too short to hold a shape, and it's usually itching at the same time. Knowing that's coming is most of getting past it.
Can I speed up beard growth? Not meaningfully. Nothing in a grooming routine changes the rate. Minoxidil is the one option dermatologists discuss for facial hair. It's a drug, not a grooming product, and the AAD advises talking to a dermatologist before using it on your face.
Does a beard grow evenly on both sides? Rarely. Faces aren't symmetrical and neither is growth. This matters most when you start shaping at four weeks. Set each side against landmarks on that side of your face rather than matching one to the other, or the beard climbs over time.
