How Long Does It Take Hair To Grow?

Hair growth is a funny thing, and can affect every single person differently. You will meet some people who can grow a beard within a couple of months, while others will have lost all the hair on their head by the time they reach 30.

The different parts of your body contain different types of hair follicles, and due to certain factors, the hair will grow at faster and slower rates.

How Long Does It Take Hair To Grow?

In this article, we will discuss how long it takes for the average person’s hair to grow, as well as looking at the factors that can reduce hair growth.

How Long Does It Take To Grow Hair?

For the sake of this article, we will be focusing on the growth of the hair on your head, and won’t be focusing so much on other bodily areas.

However, below, we have mentioned the amount of time it takes for facial and pubic hair to grow, as well as your head hair.

Head Hair

The hair on your head can only grow so quickly since its rate of growth is often determined by an individual’s gene coding, which results in a monthly average growth of half an inch. Hair typically grows around 6 inches within a year.

Hair growth can slow down as a person gets older, since cell division also slows down.

Typically, between the ages of 15 and 30, when the process slows down, are the prime years for hair growth. Once these years have passed, men may start to lose hair, or notice receding hairlines.

Hair loss can occur at any age, however, despite the prime time seeming to be when you enter your 30s. However, hairlines can begin to recede as early as the end of puberty.

By the age of 50, around 50% of men will have experienced male pattern baldness. This will depend on the person’s genetic make up, as well as other factors in their lives.

Facial Hair

While the majority of the body’s hair will grow at a comparable rate, it is predicted that your facial hair will grow at a rate of close to one quarter of an inch every month. 

If you were to grow your facial hair for a full year without shaving, you may expect to have grown a beard with a length of around 3 inches.

Of course, again, the rate of a person’s hair growth will depend on the person themselves. Some people may be able to grow a full beard within a couple of months, while others will take years to grow one.

Facial hair tends to start growing in small amounts between the ages of 11-15, at the very start of puberty.

However, studies have shown that the average age for a man to begin fully growing a beard is between the ages of 25 and 35.

Pubic Hair

Out of all the hairy parts of your body, it may seem that your pubic hair grows at a much faster rate.

The pubic hair on the average person will reach a length of about 1 inch before starting to fall out and making place for new hair to develop.

This explains why pubic hair never seems to become very long, regardless of how long you let it grow.

Compared to other body hair, pubic hair typically grows at a consistent rate of 0.5 millimeter each day. This indicates that it will attain its maximal growth within a month or so.

Factors That Can Reduce The Rate Of Hair Growth

Factors That Can Reduce The Rate Of Hair Growth

As we mentioned earlier, there are several factors that can – and will – affect the rate in which your hair grows. Below, we have listed some of these reasons.


When it comes to hair loss, men are more likely to experience this issue compared to women. Permanent hair loss will, likely, be experienced by 70% of men, while it will only impact 40% of women.

By the age of 35, 40% of men will have experienced some form of hair loss, whether they have a receding hairline, or their hair has completely fallen out altogether.

By the age of 80, 80% of men will have experienced hair loss.

However, hair loss does not impact every man, and some men will make it to 90 years of age will a full head of hair.

Genetic Makeup

We briefly touched upon a person’s genetic makeup earlier in this post, and how it can affect a person’s hair growth and hair loss. In addition to hair color, genetic factors also influence thickness, consistency, and development. 

Dihydrotestosterone – also known as DHT – causes the hair follicles in persons who are genetically predisposed to hair loss to shrink.

Your hair density reduces generally as the hair gets weaker over time, and at some point, the hair follicle may eventually stop growing hair altogether.

So, if your father lost his hair by the time he was 35, and your grandfathers became bald by their 40s, you may want to anticipate a similar fate.


Thyroid hormone, estrogen, and testosterone are just a few of the hormones that can have an impact on hair growth.

DHT is produced when the male hormone testosterone mixes with 5AR, also known as 5 alpha reductase.

DHT is recognized as the primary factor contributing to baldness in both men and women, but it disproportionately affects men.


The most typical cause of stress-related hair loss is telogen effluvium, which forces the hair follicles into a state of repose. 

Two additional disorders that have a strong connection to distress that can cause hair loss are trichotillomania and alopecia areata.

A person’s stress level may cause more hair follicles to enter the resting stage of the hair cycle. A near-equal proportion of men and women may experience this type of hair loss.

Final Thoughts

As a man, it can be difficult to tell how long you will have a full head of hair. Depending on your genetics, age, and the amount of stress you experience on a daily basis, you may experience balding sooner rather than later.

However, you may never experience balding at all, and could leave this world at 100-years-of-age with a full head of hair.
