Why does not my hair grow? Possible causes

Here we will see the most common causes why hair does not grow.


1. Genetics

The hair growth cycle consists of three phases : anagen phase, which is when the hair grows, catagen phase, which is the transition stage, and telogen, which is when the hair falls out. This cycle is not the same in all people and is thus usually from birth.

There are some people in which the growth phase lasts 2 years and some up to 7 years, and since childhood this difference can be perceived in the time that the hair takes to grow .

It is time to remember and analyze if from childhood a slow growth in hair length has been noticed. If so, it is likely to be due to genetic issues, and a treatment supervised by a dermatologist could help the process , but it is good to understand that even then the process will be slower than the average of the people. This may be one of the many causes why hair does not grow at the pace we would like.


Another reason caused by genetics is that If the hair is curly, wavy or very thin, the perception of hair growth is that it does not grow as much , when in fact it may be growing at a good pace.

When the hair is curly, inquiries are common about why hair does not grow so much; However, to correct this erroneous perception, one can resort to reviewing the length frequently by stretching a lock and checking until the height of the back reaches. Surely over the months the perception that does not grow, will change.

2. Type of feeding

One of the most frequent reasons that hair does not grow is that the food is not adequate. The hair, like the rest of the body, It requires nutrients to grow and also be healthy .

The reason that the hair does not grow due to a bad diet, is because the body absorbs essential nutrients for the functioning of the organism and vitality, and those processes that are not urgent or that are not life or death are "sacrificed" so that If you are not ingesting an adequate amount of vitamins and nutrients in general, hair is one of the parts that is affected in the first place.


Eating enough vegetables, fruits, protein and water is the first step to recover healthy hair and encourage their growth. However, it is necessary to monitor that the diet in general is balanced and that the vegetables and fruits are appropriate according to the lifestyle and the daily requirements. An incorrect diet may be the main reason hair does not grow.

3. Stress

The body reacts in multiple ways to short or prolonged episodes of stress. Everything that is generated as a result of this, influences in an important way in the functioning of the body, and the scalp and therefore the hair is not the exception.

When we feel stress it is common for dermatitis to develop , sometimes it is not easily visible, but before it manifests itself in other areas of the body, the scalp is the one that resents it, causing a series of uncontrolles, because the dermatitis causes an excessive irritation on the scalp which in turn It results in an inflammation of the follicles that prevent normal growth. That is why one of the causes of not growing hair is stress.

When it comes to chronic stress, this delay in hair growth can be very evident because there will also be an increase in the fall; however, even in short periods of stress, this process that prevents hair growth can be notorious .

In a situation of stress, It is advisable to resort to relaxation techniques and Mindfulness to balance our mind and body and prevent it from being a reason why hair does not grow.

4. Age

Another reason why hair does not grow is age . Over the years, the body processes change, and one of the most notorious is hair growth.

The age at which hair can stop growing normally is variable, but from the age of 30 an almost imperceptible decrease can occur that will become noticeable as the years go by. It's a normal process that you have to accept and auxiliary with treatments and good nutrition, however, we must be aware that around 50 years, the main cause of not growing hair is age and decreased collagen production.

Before this cause it is recommended to go to the dermatologist to analyze the best treatment as an aid in hair growth caused by the passage of time.
