一洗头就大把大把掉头发,这样正常么?/Is it normal to lose a lot of hair as soon as you wash your hair?

关于洗头这个事儿,真的让人很烦心。

这不最近就有朋友给小艾发牢骚说:天天洗头吧,担心头发掉的厉害;不经常洗头,又担心油脂堵塞毛孔。

那么问题来了:每隔几天洗一次头,对头发最好?

如果每天都洗头,会有什么危害

“头发不能天天洗,否则头发越洗 越掉”,类似这种说法很多人都是听说过的,这些说法本身科学吗?

观点一: 天天洗头发会越掉越多?

基本不会。洗头本身不会掉头发,掉头发更多是因为激素、内分泌、精神因素等原因。正常健康的头发,是不会掉头发的。

观点二: 天天洗头头发干枯易断?

基本正确。频繁洗头总会造成一些毛鳞片的损伤,用电吹风把头发吹得很干,这些极端的做法对会加剧毛鳞片损伤,头发逐渐变得黯淡无光,而且干枯易断。

观点三: 天天洗头头皮屑会更多?

不会更多。真菌,或者头皮遭到化学物的刺激、缺乏维生素A等都可能导致头皮屑增多,但是头皮屑多少和洗头是没有必然联系的。

所以说,天天洗头并不会让头发掉得更多,也不会让头皮屑变多,但对发质有损伤却是事实。

但如果咱们长期不洗头,皮脂腺分泌的油脂和其他杂物会堵塞毛囊,影响毛囊正常生发,造成脱发。


The matter of washing hair is really annoying.

Recently, some friends have complained to Xiao Ai, saying, 'Wash your hair every day, I'm worried about severe hair loss.'; Not washing hair frequently and worrying about oil clogging pores.

So the question is: Is washing your hair every few days best for your hair?

What are the hazards of washing hair every day

Many people have heard of the saying 'hair cannot be washed every day, otherwise hair will fall out as it is washed'. Is this statement itself scientific?

Viewpoint 1: Will washing hair every day lead to more and more hair loss?

Basically not. Washing hair itself does not cause hair loss, and hair loss is more likely due to factors such as hormones, endocrine, and psychological factors. Normal and healthy hair will not lose hair.

Viewpoint 2: Is washing hair every day dry and prone to breakage?

Basically correct. Frequent washing of hair will always cause some damage to the hair scales. Using a hair dryer to blow the hair very dry can exacerbate the damage to the hair scales, making the hair gradually dull, dry, and prone to breakage.

Viewpoint 3: Will washing hair and dandruff increase every day?

There won't be any more. Fungi, or chemical stimulation of the scalp, lack of vitamin A, etc. can all lead to increased dandruff, but the amount of dandruff is not necessarily related to washing hair.

So, washing hair every day does not cause more hair loss or dandruff, but it is a fact that it can damage hair quality.

But if we don't wash our hair for a long time, the oil and other impurities secreted by the sebaceous glands will block the hair follicles, affecting their normal hair growth and causing hair loss.
