Why has my beard stopped growing?

Have you ever wondered if or why your beard has stopped growing? Understanding the three stages of hair growth can help you determine if your beard has reached its maximum length.


The Hair life cycle


The anagen stage is the active growth phase where new hair is produced. This stage can last anywhere from 2 to 6 years for most men, but genetics play a big role in determining the length of this phase.


The catagen stage is a transitional phase where the beard stops growing and the follicle shrinks. This stage typically lasts for a few weeks.


The telogen stage is the resting phase where old hair sheds and new hair begins to grow. This stage can last for a few months.


If your beard has reached terminal length, you may notice that your beard has indeed stopped growing. Keep in mind that genetics, hormones, age, and overall health can also affect the length of your beard.


Hormones and beard length

Testosterone and dihydrotestosterone (DHT) are two hormones that play a crucial role in determining beard length. Testosterone is responsible for initiating the growth of facial hair, while DHT helps to promote the development of thicker and longer beard hair.

Higher levels of testosterone can lead to increased beard growth, resulting in a fuller and more robust beard. DHT, a byproduct of testosterone, further stimulates the growth of facial hair by prolonging the growth phase of hair follicles. Individuals with higher levels of testosterone and DHT typically have faster and denser beard growth, while those with lower levels may struggle to grow a full beard.

In conclusion, testosterone and DHT are essential hormones that contribute to the growth and development of facial hair, influencing the length and thickness of a person's beard.


While testosterone and DHT play a crucial role in beard growth, having normal hormone levels doesn't guarantee a thick beard. Genetics ultimately determine beard growth.

Beard growth, male hormones, and everyday chemicals in cosmetics

Chemicals like bisphenol A (BPA) and phthalates are endocrine disruptors and can seriously affect male hormones. These chemicals are commonly found in plastics, cosmetics, synthetic fragrances, and pesticides.

Exposure to these chemicals can severely impact male hormones including a decrease in testosterone levels, which can have a range of negative effects on male health. Low testosterone levels have been linked to decreased libido, erectile dysfunction, infertility, and reduced muscle mass and strength.

Considering these chemicals directly impact the hormones responsible for beard growth, those looking for thicker, longer, fuller beards should be especially cautious.

How to minimise exposure to hormone-damaging chemicals

To minimize exposure to endocrine disruptors, it is important to be mindful of the products we use and the foods we consume. One way to do this is by choosing organic and natural products that are free from harmful chemicals such as phthalates and parabens (commonly found in synthetic fragrances).
