青少年会出现头发稀疏吗?其原因是什么?

この記事の概要

20 多岁和 30 岁出头出现的年轻秃发被称为幼年秃发。 如果早发现早治疗,年轻秃发是可以得到改善的。 本文将介绍青年秃发的原因、防治方法以及判断标准。

青少年头发稀疏的原因

在这里,我们将介绍五个被认为是导致过早脱发的因素。即使是年轻人也会出现脱发增多或头发量减少的情况。为了采取适当的措施,首先要找出头发稀疏的原因。

生活习惯紊乱

如果您的生活方式被打乱并延长,可能会导致头发稀疏。在生活习惯中,营养不均衡、睡眠不足、缺乏运动等据说与头发稀疏有很大关系。如果你只吃快餐,你最终会摄入过多的盐和热量,破坏你的营养平衡,并使你的身体更容易分泌二氢睾酮,这就是 AGA 的原因。

睡眠不足还会扰乱促进头发生长的生长激素的分泌。缺乏运动会导致血液循环不良和新陈代谢缓慢,从而使头皮无法获得足够的营养,导致头发在完全生长之前就脱落。

压力过大

过度的压力会导致头发稀疏和脱发。当人们承受巨大压力时,他们的自主神经系统就会受到干扰。自主神经系统紊乱可能会导致血液循环不良,最终可能导致头发稀疏。自主神经系统由交感神经和副交感神经组成,它们的平衡分泌维持健康。当交感神经系统因压力而占主导地位时,血管就会收缩,血流就会恶化。

基于不正确的护发知识

不正确的头发护理会导致头发稀疏和脱发。持续使用不适合自己体质的护发产品可能会恶化头皮环境,导致过早秃顶。

遗传学

AGA 是过早秃顶的原因之一,它是遗传性的,据说受到母亲遗传基因的强烈影响。因此,如果你的母系有稀疏头发,那么你继承稀疏头发基因的可能性就很大。然而,仅仅因为你的外祖父母头发稀疏并不一定意味着你会秃头。请注意,这只会增加成为 AGA 的可能性。

睾酮的变化

AGA是年轻人头发稀疏和脱发的最大原因。 AGA是指男性青春期后发生的头发稀疏,常见症状是发际线和头顶周围的头发稀疏。一旦发育,头发就会继续稀疏,因此 AGA 治疗是必要的。

AGA 是由雄性激素睾酮转化为二氢睾酮引起的疾病。它可以在任何年龄发生,早期预警信号在 20 岁出头的人中出现。女性男性型秃发称为 FAGA。

认识年轻秃顶的要点

这里有一些要点可以帮助您发现年轻的秃头。越年轻的人越认为自己不会出现头发稀疏或脱发的情况,但越晚才发现自己正在经历过早秃顶。早期治疗对于改善稀疏的头发很重要。让我们检查一下这些要点,以便您可以立即发现头发稀疏或脱发。

脱发量增加了

要识别过早秃发,请检查脱发量。简单来说就是根据脱发是否比以前更多来判断。人类的头发每天都会不断地重生,据说在正常的头发周期中,每天会有50到100根头发脱落。如果您感觉自己的脱发量超过这个数字,请考虑过早秃顶的可能性。

我的发际线正在后退

如果您的发际线比以前后退得更多,您可能正在经历早期秃顶。男性头发稀疏有几种模式。其中之一是从发际线逐渐后退。发际线呈M字型后退的形态有很多,而当你从正面看头部时,额头呈M字型,左右发际线呈深深的弯曲,预示着过早秃顶。我们想一想。

螺纹处的皮肤很明显

如果你的螺纹周围的皮肤变得明显,你可能正遭受过早秃顶的困扰。在 AGA 中,稀疏的毛发有逐渐向螺纹周围扩散的趋势。头顶头发稀疏也称为O型秃头。从后面看头发稀疏的现象更为明显,但有些人从正面看可能不会注意到。如果肤色区域开始在螺纹周围扩散,请小心。

打理头发变得很困难

随着头发稀疏或脱发的进展以及头发体积的减少,你很难像以前那样设计头发。年轻秃顶的另一个特点是,造型后头发很难长时间保持。在年轻一代中,有些人可能想要享受各种发型。如果您最近感觉头发在蜡的重量下被压碎,即使以前没有发生过,您可能正在遭受过早秃顶的困扰。

预防过早秃顶的4种方法

在这里,我们将介绍四种预防过早秃顶的方法。在日常生活中牢记这一点,可以防止过早秃顶。

审视你的生活习惯

只需检查您的生活习惯即可预防过早秃顶。主食以米饭或面包为主食,配菜以蔬菜和海藻以及肉或鱼为主,尽量饮食营养均衡,睡眠充足。此外,结合运动可以改善体内的血液循环,防止头发稀疏。

适当护理头皮

头皮按摩可以有效促进头皮的血液循环。如果在头皮温暖时(例如洗完澡后)进行此操作,可以获得更好的效果。用指尖轻轻刺激头皮,以改善血液循环。

过着无压力的生活

强烈的压力会导致头发稀疏和脱发,所以尽量过无压力的生活方式。我们建议您花时间让身心得到休息,找到一种能让心情焕然一新的爱好,并以适合您的方式缓解压力。

接受AGA治疗

一种方法是如果您发现过早秃发的迹象,请尽早治疗 AGA。治疗通常涉及口服或外用药物。我们将通过使用抑制头发稀疏症状的药物和增加头发体积的药物来改善早期秃发。

概括

即使您是年轻人,也很有可能会出现头发稀疏或脱发的情况。头发稀疏可以通过适当的治疗得到改善,因此,如果您开始注意到头发稀疏,建议尽快到医院或专科诊所咨询,并尽快开始治疗。

よくある質問

Q头发稀疏会遗传吗?

A头发稀疏的基因据说是由母亲的 X 染色体遗传的。 因此,如果母亲一方有头发稀疏的情况,她患头发稀疏的几率就很高。 不过,即使父亲有头发稀疏的情况,也不会遗传到这种基因。

Q未成年人可以使用生发产品吗?

A有适合青少年使用的生发产品。 年轻一代往往皮脂分泌较多,因此建议使用平衡头皮皮脂的生发产品。

Q生发洗发水能让头发生长吗?

A生发洗发水没有生发效果。 其唯一目的是通过改善头皮环境来防止脱发。 建议那些希望使用对头皮刺激较小的洗发水的人使用这类产品。

Does thinning hair occur even in young teens? What causes it and how to prevent it.

この記事の概要

Young baldness that develops in one's 20s or early 30s is called juvenile alopecia. Young baldness can be improved if it is recognized early and treated. This article introduces the causes of young baldness and countermeasures, as well as the criteria for judging the condition.

Causes of thinning hair in young people in their teens

Here, we will introduce five factors that are thought to be the cause of premature hair loss. Even young people can experience increased hair loss or loss of hair volume. In order to take appropriate measures, first find out the cause of thinning hair.

disordered lifestyle habits

If your lifestyle is disrupted and prolonged, it can cause hair thinning. Among lifestyle habits, unbalanced nutrition, lack of sleep, and lack of exercise are said to be greatly related to thinning hair. If you only eat fast food, you will end up consuming too much salt and calories, disrupting your nutritional balance, and making it easier for your body to secrete dihydrotestosterone, which is the cause of AGA.

Lack of sleep also disrupts the secretion of growth hormone, which promotes hair growth. Lack of exercise can lead to poor blood circulation and slow metabolism, which can prevent the scalp from getting enough nutrients, leading to hair loss before it can fully grow.

excessive stress

Excessive stress can cause hair thinning and hair loss. When people are under severe stress, their autonomic nervous system becomes disrupted. Disturbance of the autonomic nervous system may cause poor blood circulation, which may eventually lead to thinning hair. The autonomic nervous system consists of sympathetic and parasympathetic nerves, and their balanced secretion maintains health. When the sympathetic nervous system becomes dominant due to stress, blood vessels become constricted and blood flow worsens.

Hair care based on incorrect knowledge

Incorrect hair care can promote thinning hair and hair loss. Continuously using hair care products that do not suit your constitution may worsen the scalp environment and lead to premature baldness.

genetics

AGA, one of the causes of premature baldness, is hereditary and is said to be strongly influenced by genes inherited from the mother. Therefore, if your maternal family has thinning hair, there is a high possibility that you will inherit the thinning hair gene. However, just because your maternal grandparents have thinning hair does not necessarily mean you will go bald. Please be aware that this only increases the possibility of becoming AGA.

Changes in testosterone

AGA is the biggest cause of hair thinning and hair loss in young people. AGA refers to hair thinning that occurs in men after puberty, and a common symptom is thinning of the hair around the hairline and crown of the head. Once developed, hair thinning continues to progress, so AGA treatment is necessary.

AGA is a condition caused by the conversion of the male hormone testosterone to dihydrotestosterone. It can develop at any age, with early warning signs appearing in people in their early 20s. Male pattern baldness in women is called FAGA.

Points to recognize young baldness

Here are some points to help you spot young bald people. The younger a person is, the more they think that hair thinning or hair loss will not occur to them yet, and the later they notice that they are experiencing premature baldness. Early treatment is important to improve thinning hair. Let’s check the points so that you can immediately detect thinning hair or hair loss.

The amount of hair loss has increased

To identify premature baldness, check the amount of hair loss. It is simply determined by whether or not there is more hair loss than before. Human hair is repeatedly reborn every day, and it is said that during a normal hair cycle, 50 to 100 hairs fall out each day. If you feel that you are losing more hair than this number, consider the possibility of premature baldness.

My hairline is receding

If your hairline is receding more than before, you may be experiencing early baldness. There are several patterns of thinning hair in men. One of them is gradual receding from the hairline. There are many patterns in which the hairline recedes in an M-shape, and when you look at your head from the front, the shape of your forehead looks like an M, and the left and right hairlines are deeply curved, indicating premature baldness. Let’s think about it.

The skin of the whorl is noticeable

If the skin around your whorls becomes noticeable, you may be suffering from premature baldness. In AGA, there is a tendency for thinning hair to gradually spread around the whorl. Thinning hair on the top of the head is also called O-shaped baldness. Hair thinning is more noticeable when viewed from the rear, but some people may not notice it from the front. Be careful if the skin-colored areas start to spread around the whorl.

It has become difficult to set my hair

As hair thinning or hair loss progresses and the volume of your hair decreases, it becomes difficult to style your hair the way you used to. Another characteristic of young baldness is that it is difficult to maintain the hair for a long time after styling. Among the younger generation, some people may want to enjoy various hairstyles. If you feel like your hair is getting crushed under the weight of wax recently, even though it hasn’t happened before, you may be suffering from premature baldness.

4 ways to prevent premature baldness

Here, we will introduce four ways to prevent premature baldness. Keep this in mind in your daily life to prevent premature baldness.

Review your lifestyle habits

You can prevent premature baldness just by reviewing your lifestyle habits. Eat rice or bread as a staple food, vegetables and seaweed along with meat or fish as a side dish, try to eat a nutritionally balanced diet, and get enough sleep. Also, incorporating exercise can improve blood circulation in your body and prevent hair thinning.

Take proper scalp care

Scalp massage is effective for promoting blood circulation in the scalp. You can expect better results if you do it when your scalp is warm, such as after taking a bath. Gently stimulate your scalp with your fingertips to improve blood circulation.

live a stress-free life

Strong stress can cause hair thinning and hair loss, so try to live a stress-free lifestyle. We recommend taking time to rest your mind and body, finding a hobby that refreshes your mood, and relieving stress in a way that suits you.

receive AGA treatment

One way is to treat AGA early if you see signs of premature baldness. Treatment generally involves oral or topical medications. We will improve early baldness by using drugs that suppress the symptoms of thinning hair and drugs that increase hair volume.

summary

Even if you are a young person, there is a good chance that you will experience hair thinning or hair loss. Thinning hair can be improved with appropriate treatment, so if you start to notice thinning hair, it is recommended to consult a hospital or specialized clinic as soon as possible and start treatment as soon as possible.

よくある質問

QIs thinning hair hereditary?

AThe gene for thinning hair is said to be inherited from the mother's X chromosome. Therefore, if someone on the mother's side of the family has thinning hair, there is a high probability that she will develop thinning hair. However, even if the father has thinning hair, the possibility of inheritance is not zero.

QCan hair growth products be used by minors?

AThere are hair growth products that can be used by teenagers. Young people tend to be more active in sebum secretion, so it is advisable to use a hair growth product that balances sebum in the scalp.

QDoes hair growth shampoo make hair grow?

AHair-growth shampoo has no effect on hair growth. The sole purpose is to prevent hair loss by improving the scalp environment. This product is recommended for those who want to use a shampoo that is less harsh on the scalp.
