On the face of it, growing a beard can be as simple as skipping shaving, but like scalp hair, facial hair follows a specific growth process. Also, the stages of beard growth are affected by a number of external and internal factors. Together, these can determine how long, thick and quickly your beard grows. So if you’ve ever wondered why your beard seems patchy or stops growing past a certain point, it all comes down to the biology behind the beard growth cycle. In this post we’ll explore the different stages of beard growth, timelines and what affects every step of this process. We’ll then share the best ways to care for your beard at every stage to support healthier, fuller growth and prevent thinning or patchiness.
Stages of Beard Growth
Like on the scalp, beard hair goes through a continuous cycle of growth, rest, shedding and renewal. Each hair follicle is at a different stage at any given time. This is why you don’t suddenly shed all your beard hairs at once but is also the reason why hair can grow unevenly. The four main stages of beard growth are:
- Anagen (Growth): This is the active growth phase during which the hair follicle receives nutrition from the blood supply to stimulates it to produce new cells to grow and push the hair shaft out of the skin. For beard hair, this stage typically can last anything from a few months to 8 years. The longer your follicles stay in the anagen stage, the longer your beard can grow. Due to its length, up to 90% of your beard hairs are usually in this stage at any time. Most visible progress during the early beard timeline comes from this stage.
- Catagen (Transition): This short transitional phase usually only lasts about 2-4 weeks. During catagen, the follicle begins to shrink and detach from its blood supply. Growth stops, and the follicle enters a rest state. Although brief, this stage is important as it allows the follicle to reset before entering the next stage of the beard growth process.
- Telogen (Resting): In this stage, the hair is no longer growing but remains in the follicle. Beard hairs can stay in the telogen phase for a few months. Around 10–15% of your facial hair is in this stage at any given time. During periods of stress or hormonal shifts, more follicles may enter the telogen stage. This can result in noticeable thinning, hair loss or slower beard growth.
- Exogen (Shedding): This overlaps with the telogen phase and refers to the actual release of the hair from the follicle. The exogen phase is a part of the beard growth cycle and is necessary to make way for new hair follicles to grow. It is normal to lose anywhere from 10 to 50 beard hairs every day though this can vary from season to season. However, excessive shedding or clumps of beard hair falling out are not normal. These may indicate stress, nutritional deficiencies or underlying skin conditions.
Beard Growth Timeline, Here’s What to Expect Month by Month
Everyone’s beard journey is different because its shaped by a combination of genetics, hormones, age and your overall health. So whilst some people may see rapid and even growth early on, others might experience patchiness, slower progress or differences in density across the face. Despite these individual differences, most beards follow a broadly predictable pattern of growth and timeline. Below is a typical timeline of the stages your beard is likely to pass through as it grows:
- Stubble Stage (Weeks 1–2): In the early days, you’ll notice fine stubble usually appearing across the cheeks, jawline, upper lip and chin. The rate of growth varies, but it’s common to see uneven or patchy areas at this point. Mild itchiness is also very common as the hair starts to push through the skin. Try to keep the beard area clean, moisturised and free from friction (e.g. avoid over-scrubbing or shaving around the edges) during this stage. This will help reduce irritation and allows the hair to come through evenly.
- Patchy Growth Stage (Weeks 2–4): By now, the beard starts to become more noticeable but is usually patchy (especially on the cheeks or under the jawline). However, this doesn’t necessarily indicate poor growth and is mainly because different follicles mature at different rates. Whilst tempting, try to resist the temptation to trim or shape your beard too early. Doing so may cut into developing areas and worsen the patchiness. Instead, focus on boosting skin health and hydration as this improves the beard environment for continued growth.
- Filling-In Stage (Weeks 4–8): This is often the turning point where the beard starts to look fuller and more defined. Previously patchy areas begin to fill in as dormant follicles enter the growth phase. Brushing the beard gently at this stage can help train the hairs to grow in the desired direction. You can also apply a lightweight beard oil to soften coarse textures and nourish the skin underneath.
- Full Beard Stage (Weeks 8–12): Although growth rates and density will vary, most people will have a full beard by the 2-4 month mark. This is when you can now style, shape and groom it as you desire. Its also a good idea to introduce regular trimming to shape the neckline and maintain symmetry. Conditioning the beard with oil or balm can also help reduce dryness and keep the hair manageable.
- Mature Beard Stage (3–6 Months and Beyond): As you continue to grow your beard beyond three months, it enters what’s considered the mature stage. The hair usually reaches its genetically determined length if left uncut. The beard will also increase in density and thicken overall. Maintenance is key at this point and generally requires regular cleansing, conditioning and trimming. This will help to prevent split ends, knots or skin irritation.
What Affects the Beard Growth Process?
There are a range of internal and external factors which influence the beard growth stages and timeline. This includes how thick it becomes and how long it can grow. The most common important factors that affect beard growth include:
- Genetics: Your DNA largely determines your beard’s growth rate, thickness and terminal length. If close family members have full, thick beards, you’re more likely to experience the same. However, its not the only factor as patterns can differ even between siblings.
- Hormones: Testosterone and dihydrotestosterone (DHT) are the primary hormones responsible for stimulating facial hair growth. Higher sensitivity of the follicles to DHT often results in stronger and faster beard growth. However, excessive or insufficient levels of either hormone can also affect the beard growth cycprocessle.
- Age: Beard growth generally begins at puberty but continues to develop into your 20s and even all the way into your mid 30s. Most men see the most consistent and fullest growth around their late 20s. This is when hormonal levels stabilise and the growth process becomes more efficient. In later age, beard growth may slow down as can the thickness of hair follicles.
- Nutrition: A diet rich in protein, healthy fats, B vitamins (especially biotin), zinc and iron is essential for supporting hair follicle activity and growth. Deficiencies in any of these nutrients can impact the quality and length of beard hairs as well as their speed of growth.
- Stress & Sleep: Chronic stress can disrupt the hormonal signals involved in the growth cycle and push more hairs into the resting or shedding phase. Similarly, inadequate sleep can impair tissue repair and hormone regulation, both of which are important for hair health.
- Health: Skin is essential for supporting beard growth as hair follicles thrive best in a balanced healthy environment. Conditions like acne, seborrhoeic dermatitis, eczema or psoriasis can cause inflammation, clog follicles or disrupt the beard growth process. Likewise, medical problems like thyroid disorders, autoimmune conditions or hormonal imbalances can interfere with facial hair development. Some medications may also contribute to hair loss or slower beard growth. If you’re noticing persistent shedding, patchiness or irritation, seek medical help to check if there’s an underlying health problem causing it.
How to Support Beard Growth at Every Stage
Whilst you can’t alter your genetics, you can influence many of the factors that affect beard growth. Beard hair thrives when follicles are well-nourished, the skin is healthy and the body is functioning optimally. Whether you’re just starting out or maintaining a full beard, a more holistic approach can help encourage denser, stronger and more consistent growth. Here are our top tips for taking care of your beard hairs throughout all the stages of growth :
- Skincare: Healthy skin is the foundation for consistent beard growth throughout the timeline. Keep your face clean with a gentle cleanser to remove oil, dirt and bacteria that can clog pores or inflame follicles. Regular exfoliation (1-2 times per week) can also help to clear away dead skin cells, reduce the risk of ingrown hairs and maintain clear follicle openings for hair to pouch through. Moisturising is also essential especially in the early stages of beard growth to reduce itchiness and irritation. Lastly, if your beard is patchy or short, don’t forget sun protection!
- Beard Care: As your beard begins to fill in, it’s important to shift your focus to proper maintenance. Applying beard oil or balm keeps the hair soft, minimises breakage and nourishes the skin beneath. You can also apply a targeted treatment if you’re having ongoing problems with hair loss or patchiness. Brushing your beard with a soft-bristled brush or combing gently helps detangle hair, train growth direction and stimulate the skin to support blood flow to the follicles. Once your beard has fully grown enough to shape, use regular trims to help manage split ends and keep it looking neat.
- Diet: Nutrition plays a key role in hair follicle function. Hair is made from keratin which is a protein. As such, ensure you eat protein-rich foods to help build stronger hairs. Essential nutrients like iron, zinc, vitamin D, biotin and other B vitamins also support the metabolic processes within the follicles. Ensure your diet contains these nutrients as they can help improve hair density and growth speed. Finally, staying hydrated is vital as dehydration can lead to dryness of both the skin and hair hence affecting beard growth, comfort and appearance.
- Lifestyle: Beard growth is affected by factors like stress and sleep. Try to get enough sleep (ideally 7-9 hours per night) in order to support cellular regeneration and hormonal balance. Regular exercise can also help stimulate blood flow and promote natural testosterone production. Additionally, managing stress is key. This is because chronic stress may disrupt the beard growth process and contribute to hair loss.
Beard growth follows a series of biological stages. Under the influence of factors like age, genetics and health this determines the growth and appearance of your beard. You can support this process by understanding each stage to creates the best conditions for growth. Whether you’re at the early stubble stage of the timeline or managing a fully grown beard, an holistic approach can help you achieve your growth goals.
