Is it normal for a teenager to lose hair

You may have a problem that “I’m still a teenager but I’m worried about hair loss …”.

It is said that every person loses hair if they have about 100 hairs a day, but if they lose more or locally, there is a possibility that hair loss has progressed for some reason.

In this article, we will explain in detail the possible causes of hair loss and how to deal with them for such teenagers. Please refer to it.

Hair loss may increase even in teens

Teenage hair loss can have a variety of causes, from a temporary increase due to stress to “alopecia.”

By understanding the cause, you can choose the appropriate remedy, so if you are a teenager and you are worried about hair loss, start by understanding the possible causes. By the way, the cause depends on the gender, so we will look at it in detail below.

Common causes of hair loss in teenage guy

First, let’s look at the following three points that are often cited as causes of hair loss in teenage men.

  • Disordered eating habits
  • Androgenetic alopecia (AGA)
  • Heredity

We also explain each countermeasure and points to be aware of, so please use it as a reference for hair loss countermeasures.

Disordered eating habits

As a teenager, your eating habits may be disturbed, such as late-night meals and diets with an unbalanced nutritional balance, due to friendships and staying up late due to study.

Of the three major nutrients, excessive intake of lipids increases the secretion of sebum and causes “seborrheic dermatitis”. It is important to note that seborrheic dermatitis can cause hair loss when the symptoms progress chronically and the scalp environment deteriorates.

Seborrheic dermatitis first causes symptoms such as redness of the affected area and dandruff lumps such as scabs appearing on the affected area. It is characterized by eczema on areas with a lot of sebum, such as the scalp and hairline.

To avoid seborrheic dermatitis, which can cause hair loss, you need to try to avoid eating too much fat. By the way, in order not to take too much fat, it is recommended to choose red meat and fish, make fried foods less, and use non-oil dressing.

In addition to excessive intake of lipids, decreased metabolism of lipids and disordered sebum secretion due to lack of B vitamins can also cause seborrheic dermatitis. Among the B vitamins, vitamin B2 and vitamin B6 are deeply involved in the excessive sebum secretion that causes seborrheic dermatitis, so take them positively.

Foods high in vitamin B2 and vitamin B6 are as follows. Please refer to it for the prevention of seborrheic dermatitis.

  • Vitamin B2: liver, eel, natto, green and yellow vegetables
  • Vitamin B6: fish and shellfish, chicken, garlic, banana

Androgenetic alopecia (AGA)

Many people may know “AGA” as a disease that causes symptoms of thinning hair.

Although it may be thought that it is a disease that occurs after a certain age, AGA is actually alopecia that can be seen after puberty, and men in their late teens may also develop AGA. It is.

In addition, AGA is a progressive disease, and it is said that the secretion of growth hormone secreted during puberty has a great influence on the progression of AGA. In order to avoid stress caused by worrying too much, let’s try to suppress the progress of AGA by taking measures such as reviewing personal life.


Heredity is one of the factors that cause AGA.

AGA is caused by the hormones “dihydrotestosterone” and “receptors” that are produced by the combination of the male hormone testosterone and the enzyme 5α-reductase. Since both the activity of 5α-reductase and the sensitivity of the receptor are inherited from the parent to the offspring, if the parent is AGA, the male son is also more likely to develop AGA.

The detailed relationship between AGA and heredity is explained in detail in the following article, so please check it as well.

Common causes of hair loss in teenage girl

Next, let’s look at three common causes of hair loss in teenage women.

  • Traction alopecia
  • stress
  • Color perm

For women, I think that many people make hairstyles that make the most of their long hair and dye their hair, but such actions can lead to increased hair loss. If you are worried about hair loss, try to take care of it daily while being aware of the causes introduced below.

Traction alopecia

“Trucking alopecia” is alopecia caused by the load of tying hair, and is alopecia that women who tie hair more often than men should be careful about. If your hair is pulled hard and stressed, you are more likely to develop traction alopecia.

In particular, there is a possibility that hair loss will increase from the parts and divisions that are easily pulled when tying, so if hair loss has such characteristics, it is possible that traction alopecia is possible. In order to continue to enjoy your favorite hairstyle, try downstyles by reducing the number of times you tie your hair, or change the way you tie your hair to improve or prevent traction alopecia.


“Telogen effluvium” may be caused by stress-induced hormonal imbalance or unreasonable diet. “Telogen effluvium” is alopecia in which a certain amount of hair enters the telogen phase and comes off in bulk.

Find your own way to relieve stress and avoid accumulating stress. Also, if you worry too much about hair loss, it can cause further stress. It is also important not to be too particular about the amount of hair loss and the appearance of the hairline.

Color perm

In general, women tend to perm and color more often than men for fashion.

The irritation of colorants and perms can cause hair to accumulate damage and the scalp environment to deteriorate. If the scalp environment deteriorates, it may be difficult for healthy hair to grow and it may lead to hair loss, so be careful.

In particular, repeated use of over-the-counter colorants and bleaching agents that are highly irritating can easily cause hair loss.

However, color perms are not completely NG, and it is important to review the frequency and the chemicals used so that the damage is minimal. If you are undergoing treatment at a beauty salon, it is a good idea to ask “I want you to use a drug that causes less damage.”

Is the condition of the scalp and hair okay? Checklist for teens

As a teenager, you may not know much about the hardness and hair quality of your scalp. However, it is very important to know these in order to prevent hair loss.

In the following, while explaining why checking the condition of the scalp and hair quality is important for hair loss prevention, we divide it into two points, “scalp hardness” and “hair health”, and scalp for teens. Here’s how to check your hair.

Scalp hardness

The stiff scalp has various cosmetic and physical effects. The stiff scalp is due to poor circulation that prevents nutrients from reaching the hair roots. If the necessary nutrients are not delivered to the roots, the hair will not grow easily and may result in hair loss.

The ideal hardness of the scalp is said to be “a state where it has moderate elasticity and elasticity and moves when rubbed.” Check the hardness of your scalp as follows.

  1. Check if the hardness of the scalp and the forehead are the same
  2. Spread your fingers and grab your scalp
  3. While holding it, move your finger in a circular motion
  4. Check if the scalp and fingers move together

The scalp is an extension of the forehead, so the hardness should normally be the same. If your scalp feels stiffer, it’s evidence that your scalp is stiffer.

In steps 2-4, check the softness of the scalp itself. If the scalp and fingers move together, it can be said that the scalp is soft and healthy, but if the scalp hardly moves, has no elasticity, or is buoyant, the scalp may be in an unhealthy state. There is a sex, so try to deal with it as soon as possible.

See also this article for information on how to improve the hardness of your scalp and how to prevent it from becoming stiff.

Hair health

It is very important to check the health (condition) of the hair that is growing now and make sure that it is not worse than before in order to prevent future thinning hair. Check the health of your hair from the two perspectives of “hair quality and volume” and “how hair grows and falls out”.

First, check “Hair quality and volume”. As a premise, the thicker the hair, the healthier it is. If you feel that weak hair, such as downy hair, has increased, and that you feel less firm and firm, it may be due to a disordered hair cycle or malnutrition of the scalp. If left untreated, it may lead to hair loss, so it is necessary to take measures to grow thick and healthy hair.

Also, if you feel that the hair quality and quantity of the temporal region, crown, and bangs are different from those of the other parts, there is a risk of local hair loss. It’s a good idea to take immediate care, such as consulting a hospital.

Next, check “How to grow and remove hair”. If you feel your forehead is wider than before, or if you have more hair loss, it is possible that your hair loss is progressing. It is natural to lose about 100 hairs a day, but if you are clearly missing more than 100 hairs or increasing the number of hairs, you need to be careful.

3 ways to deal with hair loss starting from teens

By checking the condition of your scalp and hair quality, many people may feel more motivated to deal with hair loss.

Here, we will introduce three ways to deal with hair loss that can be started from teenagers. There are also free and daily workarounds, so if you want to take measures against hair loss right away, please check it out.

Shampoo review

Choosing a shampoo while paying attention to its detergency and ingredients is the first step to prevent hair loss.

This is because shampoo with strong detergency will wash off oil more than necessary if it is used in excess of the proper amount. It is important to note that dry scalp due to lack of oil may cause scalp troubles such as dandruff and hindering hair formation, which may lead to hair loss.

Shampoos can be broadly divided into the following three types, and there are differences in detergency and ingredients.

Shampoo classificationfeatureMain ingredients
Alcohol-based・ Strong detergency
・ Relatively inexpensive pricing
・ Depending on the amount used, it may cause the scalp to dry.
・ Sodium lauryl sulfate
・ Sodium laureth sulfate
・ Ammonium laureth sulfate
Soap type・ Strong detergency
・ Moderate irritation
・ Alkaline shampoo
・ Hair may squeak unless rinsed for a long time
・ Fatty acid sodium
・ Fatty acid potassium
・ Soap base
Amino acid system・Moderate detergency ・ Moderate
・ Hair with hair styling agent needs to be “pre-washed” with hot water
・ Methylalanine
・ Glutamic acid
・ Glycine

For dryness and low sebum (especially women), it is important to choose an amino acid shampoo based on the condition of the scalp, or a shampoo that contains a lot of moisturizing ingredients.

Scalp massage

A scalp massage promotes blood circulation in the scalp and makes it easier for nutrients to reach the hair, so it can be expected to prevent hair loss. It also prevents scalp sagging and gray hair, and will help maintain a healthy scalp environment in the future, so it is recommended to start from a teenager.

The trick is to use the fingertips, the entire finger, the lower part of the palm, etc. to combine “push”, “rub firmly”, and “momu” to massage the scalp. It is recommended to do it after taking a bath with a smooth scalp, so why not add some effort to your out bath time?

Scalp care with hair restorer

Some may think that “hair-growth agents are early for teens” and “hair-growth agents should be used after they get older.” However, there is no age limit for the use of hair restorers.

Using a hair restorer will improve the scalp environment and prevent hair loss, so there is no loss in using it from a teenager.

However, if you don’t use the hair restorer for a certain period of time, you can’t expect the effect, so choose one that can be used for a long time. Considering the possibility of working on it in the long term and the burden on your wallet, it is recommended to choose a hair growth agent that is easy to use at a price that you can buy continuously.

Understand the cause of hair loss in teens and deal with it appropriately

You may think that you will not suffer from hair loss as a teenager, but even teenagers can have more hair loss due to various causes such as stress and alopecia.

Not only the disorder of eating habits peculiar to teens, but also heredity, traction alopecia, color perm, etc. may be the cause, so first refer to the causes of hair loss seen in teens introduced in this article. Let’s start by understanding the cause of our own hair loss.

If the cause is found, it is recommended to deal with each of them and then perform scalp care using hair growth agents such as “Polypure EX” as a plus alpha. There is no age limit on the use of hair restorers, so even teens can easily get started.

In order to maintain a healthy scalp and hair in the future, why not take measures against hair loss from your teens?
