How much hair grows on an adult person on average per month? All about its life cycle

Have you ever wondered how much hair grows in an adult person on average per month? To take care of the health of your hair, you must start from the basics and manage information about what happens to it in our body.

Knowing the life cycle and hair loss, for example, will allow you to take care of your hair both with the application of simple and effective products and with specific treatments that are usually done in hairdressing salons or after consulting a specialist.

To understand how much hair grows in an adult person on average per month, it should be noted that the activity of each hair follicle is unique and different. This means that they are directly synchronised with each other, allowing the hair to have a constant and continuous replenishment.

The hair follicle normally produces a lot of hair throughout its life after a cycle involving stages of active hair growth, alternating with stages of rest. It should be noted, however, that the adult scalp has a fairly standard surface area, and may even differ from one individual to another.

We will now delve into how much hair grows in an adult person on average per month.

Stages of hair growth

Hair is constantly changing. There is a continuous recycling of hair on our head, even if we notice little or especially at seasonal changes.

You should only pay attention to hair loss when it is abnormal. Each of us differs in the amount of hair and the speed and growth. In addition, the causes of hair loss are also individual, in fact, they can be summarised in hormonal, genetic or stress problems.

In any case, we always recommend consulting a doctor and specialist when you think it is necessary. Let's look at the key points of the hair life cycle:

  • The life cycle of hair has a variable duration and depends on each one of us. Generally, in a woman it lasts 5 or 6 years.
  • The first phase of growth is called anagen. It lasts for many years, almost the entire hair cycle. In this phase, the hair is nourished, stretched and grows.
  • The second phase is called catagen. At the end of its growth, the hair stops feeding and stretching. The hair moves away from the hair follicle as it begins to rest. The phase lasts about three weeks.
  • The third phase is called telogen. As they say colloquially, the hair is "dead" even if it remains weakly attached. It lasts for about three to four months. In practice, it is this hair that falls out while you comb your hair and in a completely normal way during the day.
  • After the hair falls out and before the new anagen phase, the hair follicle is at rest for a short time. In general, a follicle produces more than one hair, from two to five. For this reason, it can be considered a hair unit.

How much hair grows in an adult person on average per month?

Determining how much hair grows in an adult person on average per month depends from person to person. In general, we lose just over 1000 hairs per month with an average of 40-100 hairs per day, which are replaced by new hairs.

And how many centimetres does a hair grow? A hair grows on average 0.30 millimetres in a day. In a month, the growth is approximately 9 millimetres, i.e. approximately one centimetre per month.

Factors influencing hair growth

Hair growth depends first of all on personal factors, i.e. genetic aspects, then clearly on the individual's age, sex and ethnic origin. In Asians, hair grows more (1.3 cm) than in Europeans (1.2 cm) while in African populations hair grows less than in other ethnic groups.

In terms of gender, hair grows more in women than in men. Age is also an important factor, considering that the life cycles of a young person are fast. Whereas as the years go by, the growth rate tends to slow down.

However, the average is about 1 millimetre per day, the night more slowly, in the morning faster, with the heat increases the speed of growth, which is why in certain periods it seems to us that the hair has stretched quickly.

Things to consider for optimal hair growth

An important factor for hair growth is the pollution present in the air which negatively affects their development. The presence of wind also has an influence, tending to dry them out.

The way you live, even the right diet, helps your hair grow - in fact, the nutrients in your scalp determine the health of your hair.

We therefore recommend:

  • Eat fruit, vegetables, meat and fish.
  • Hair care is also essential, avoiding overly strong and stressful treatments.
  • Caring for the root of the hair and treating both the length and the ends is essential for its health.
  • Keeping hair tied up too often, using brushes that are too hard or using devices such as straighteners or hairdryers means stressing the hair, making it brittle and more prone to breakage.
  • Use quality products such as shampoo and conditioner (specific to your hair type).
  • Having foresight in the case of particularly dry hair and using conditioner before brushing can also greatly benefit its health and care.
  • Long hair should be checked and cut when brittle, to regain its fullness.
  • The habit of applying weekly compresses based on olive oil or specific products will help hair to grow healthy and shiny.
  • For those with normal, not excessively greasy hair, the shampoo can be used once or twice a week, while for those who tend to have greasy hair, it would be better to use this product three or four times a week.

Conclusions

Hair growth is definitely a complex process involving many factors, including genetics, hormones and general health.

On average, hair grows between 1 and 1.5 centimetres per month, however, this growth can vary from person to person, depending on age, ethnicity and other factors.

Now, to maintain a healthy and strong head of hair, it is important to take care of the scalp and use quality products. It is also key to avoid stress, which can affect hair growth.
