Why does hair stink if you don't wash it?

1. The sebum secretion of the head is active, and it is easy to smell.

The head is especially rich in sweat glands compared to other parts. Moreover, there are many sebaceous glands in the head. There are 220 sweat glands on the head** per square centimeter.

while 140 for the face and 130 for the back. The head is not heat-tolerant and needs to be dissipated by sweating profusely on the head. When the head sweats a lot, the secretion of sebum becomes active, so of course it is easy to smell.

The secreted sebum and sweat are acidified by the bacteria and become "sebaceous acid", which emits odor.

2. Dandruff is also the cause of odor.

The head is located on top of the nose, so the nose basically can't smell its own head. That alone is enough to make a lot of people fidget. People who are very concerned about the smell of their heads have to wash their hair desperately.

However, washing your hair too much will wash off too much sebum, which will continue to be secreted more and more, and will also produce a lot of dandruff. Dandruff is actually a clump of keratin and sebum, which is a very tasty meal for bacteria, and as a result, bacteria live in the dandruff. Quickly multiplies and becomes a source of odor.

3. In addition to the "smell of the scalp", the hair also absorbs a variety of other odors.

When we talk about "head odor", it is not only through the scalp, but also through the hair. Hair is susceptible to a wide variety of odors. The smell of car exhaust, the smell of cigarettes, oil smoke, and alcohol ......Many people have experienced that when they go home and wash their hair, they will smell of cigarettes from the store they just visited.

Hair absorbs odors present in various life scenarios. Because it is tens of thousands of filaments, the surface area is quite large, and it is very easy to absorb odors on these fine hair strands, and it is difficult to remove.

4. Wet hair and split ends and broken hair are easy to get odors.

Healthy and innocuous hair is difficult to absorb odors, and injured hairs with many split ends or fractures stick to each other and are easily contaminated by the ingredients in the smell, so you should be careful not to rub excessively, rinse too much, blow dry excessively when shampooing, etc.

5. The smell of the head also becomes strong with mental stress, drinking, lack of sleep, etc.

To get rid of head odor, it is more effective than blindly shampooing to control the greasy diet. People with strong sebum secretion will naturally weaken as long as the taste is light. In addition, it is easy to control the amount of alcohol you drink, relax your mood, and get enough sleep, so that you can improve your lifestyle habits as a whole.

Because the secretions and dust on the head can encourage the growth of fungi when the temperature is wet, it will smell if you don't wash your hair.

The head sweats and discharges just like **. The air is mixed with a lot of microscopic matter and dirt, which falls with the dust in your hair, and begins to multiply and produce excrement under the nourishment of sweat and secretions. That's the stinking **.

Therefore, the head needs to be washed frequently.

Because there are bacteria without washing your hair, the bacteria will gradually multiply and grow, and the metabolic wastes produced and the metabolites excreted by the body will become bad after a long time.

If your hair is left unwashed for a long time, sweat, oil, and bacteria can accumulate on your hair and scalp. These substances provide a humid, warm, and nutrient-rich environment that is ideal for bacterial growth and reproduction. Bacteria break down sweat and oil on the hair and scalp to produce compounds called ketone bodies, which give off an unpleasant odor that can make hair smelly.

In addition, bacteria and fungi on the hair can also grow and multiply without washing for a long time. Bacteria and fungi need a moist and warm environment to grow, and the oil and dandruff of the scalp and hair can also provide them with nutrients. If you don't wash your hair for a long time, bacteria and fungi can grow on your hair and scalp, further aggravating the odor.

Therefore, to keep our hair clean and healthy, we need to wash our hair frequently. Washing your hair can effectively remove oil and dirt from your scalp and hair, reduce the growth of bacteria and fungi, and avoid hair from becoming smelly. At the same time, choose the right shampoo and scalp care solution, such as the Silk Chemours Home Care Package, which consists of a head skin care solution and shampoo, which can be used at home for a long time to improve scalp relief and balance oil, and the scalp care solution can also replenish the nutrients needed by the scalp and hair follicles.

At the same time, paying attention to the cleanliness and moisturizing of the scalp can keep the hair healthy and Mercer Xiaohuili.

With the development of society, people's perception of beauty has changed greatly. It's not uncommon to hear about who has the right hairstyle and whose hair tastes unique. Some people are so busy all day at work that they don't have time to clean up their hair and don't care much about these details.

In general, hair smells bad for three reasons:

1. Excessive sweating, resulting in smelly hair. Due to the heat of the weather, some people have a large secretion. Or some people are inherently sweaty, and the head is the one with the most sweat glands.

When it's hot, you'll sweat more. Sweating inherently has a little smell, and with excessive secretion, the taste will be even greater. If you don't wash your hair often, the smell can stretch and cause your hair to stink.

2. Dandruff can also cause hair to stink. Many people think that if they can't smell it, others will certainly not smell it, which is a wrong view. If the head grows on oneself, it will definitely not be smelled, but others are different, a little wrong, and others will know it clearly.

It's just that some people are willing to say it, but some people are unwilling to say it. Many people will also think like this, since there is such a need to remove too much dandruff, then wash your hair every day, it will always decrease. In fact, this idea is not right, you must know that too much hair washing will not solve these problems, but will lead to sebum washing and dandruff will increase.

3. Sleep before your hair is dry. Many people like to dry naturally after washing, and sometimes the hair is not completely dry, so they go to sleep. This can lead to the growth of bacteria and the hair will stink.

If you really can't wait, you can use a hair dryer. Blow-drying your hair can drive away some bad smells.

4. Hair easily absorbs other odors. Smoking is often encountered in the vicinity. Friends who drink alcohol, even if you don't drink alcohol or smoke, you will have this taste on you.

Because the smell of other people's smoking and drinking alcohol will also be adsorbed on you, and this smell will also appear on your hair, so that your hair will stink.

Wash your hair at least once every two to three days, choose a shampoo that is suitable for your hair, pay attention to use conditioner if your hair is too dry, and pay more attention to maintenance. Don't exercise too much, pay attention to food, and don't eat anything too spicy.
