During childhood, most boys have thick, shiny and healthy-looking hair. As men grow older, however, many gradually experience hair thinning, hair loss, or even baldness.
This made me wonder: why does age seem to have such an important connection with hair volume?
One observation that led me to my own way of thinking is that, during childhood, boys generally have very little body hair apart from the hair on their scalp. As they enter their teenage years, hormonal changes gradually lead to hair growth in many other parts of the body.
So, as a boy becomes a man, the body's overall requirement for nutrients such as proteins and vitamins may also increase because more parts of the body are developing and being maintained.
My thought is that we often don't respond to this change by improving our diet.
In fact, after our teenage years, many people start eating less or paying less attention to nutrition because they are worried about gaining weight. Studies, jobs, financial responsibilities and a more sedentary lifestyle can also change our eating habits.
So I personally wonder whether, in some cases, the nutrients we consume may not be sufficient to support everything our body needs—including maintaining healthy scalp hair.
My Simple Way of Looking at It
If a person wants to maintain good hair as they grow older, I believe good nutrition becomes increasingly important after the teenage years.
If weight gain is a concern, my thought is not to simply reduce food or protein. Instead, carbohydrates and unnecessary calories can be reduced while maintaining sufficient protein and nutritious food, along with appropriate physical activity.
For someone working in a sedentary profession, such as software development, regular exercise becomes particularly important to balance the reduced physical activity of the job.
People whose professions already involve substantial physical activity may naturally have an advantage in this regard.
Why Do I Think About Men Differently?
My observation is that men's body hair generally increases considerably after puberty. Women, on average, don't experience the same degree of body-hair growth.
This makes me wonder whether the nutritional requirements associated with maintaining body tissues and hair may also differ between men and women.
Again, this is simply how I am connecting the observations I have made. It is not a scientific conclusion.
The Change in Modern Work
There is another major change that I feel is worth considering.
For much of human history, men generally performed occupations that involved considerable physical work—farming, construction, transportation, manual labour and many other physically demanding activities.
Their daily work itself required them to use their bodies.
But modern technology has changed this dramatically.
Today, many men work in software and other desk-based professions. We can spend eight or ten hours working intensely with our minds while barely moving our bodies.
So perhaps there is a difference between the physical demands of our body and the physical activity our modern lifestyle provides.
Earlier, a person could work hard physically, eat well, and naturally use much of that energy through the day's work.
Today, someone may eat the same way—or sometimes even reduce their food because they fear weight gain—while spending most of the day sitting.
If we reduce food too much, we may not necessarily be giving the body everything it needs. And if we don't exercise, we may gain weight because our daily physical activity has reduced.
This creates a situation where we have to manage both sides consciously:
Eat enough nutritious food to support the body, while maintaining enough physical activity to manage excess weight.
My Personal Takeaway
My simple belief is:
As men grow from adolescence into adulthood, they should not neglect their nutrition while trying to control their weight.
If you want to reduce excess weight, reduce unnecessary calories or carbohydrates if appropriate, stay physically active, and focus on maintaining a good-quality diet rather than simply eating less.
For me, the broader lesson is that growing older means our body's needs also change.
We shouldn't expect the same lifestyle and diet that worked at 15 to necessarily be enough at 25, 35 or 45.
Whether this explains hair loss or not, I feel that taking care of nutrition, physical activity and overall health becomes increasingly important as we grow older.
Yes. This fits naturally into your “My Observation” section. I would phrase it carefully so your personal theory is clear without presenting it as established science.
Does Everyone Need the Same Diet?
Another thought that comes to my mind is that perhaps there cannot be one identical diet requirement for every person.
Our nutritional needs can vary according to several factors:
- Age
- Gender
- Height and weight
- Profession and physical activity
- Overall lifestyle
- And, in my personal way of thinking, even the amount of body hair
After puberty, not every man develops the same amount of body hair. Some may have more hair on their beard, chest, arms or other parts of the body, while others may have considerably less.
If my earlier observation has any validity, then perhaps a man with more body hair may have different nutritional requirements from another man of the same age who has much less body hair.
So, if a man has substantial body hair growth and is also experiencing scalp hair loss, I personally wonder whether he may need to pay even more attention to getting sufficient nutrition, compared with someone of the same age who has considerably less body hair.
This is something I rarely see discussed when people talk about diet and hair loss.
Again, I am not saying that body hair automatically causes scalp hair loss or that more body hair definitely means a person needs more nutrition. This is simply the connection I have been thinking about from my own observations.
My broader point is that perhaps nutrition should not be looked at as a fixed formula based only on age or gender.
Every person's body is different, and perhaps our nutritional requirements are different too.
This is my personal way of looking at the subject. You don't have to accept it as fact—it is simply an observation that made me think differently about hair loss in men.
