What is the white dirt on your hair if you don't wash it for two or three days?

In daily life, we often have this symptom-scalp itching. Once itching occurs, I believe that most people will make the same action-scratching. Every time we scratch our scalp with our hands, we will find some white dirt under our fingernails, which leads to the topic in our topic: what is the dirt that is deducted from our heads?

For most people, the normal metabolism of scalp cells will produce exfoliated keratinocytes, but these cells are very few in number. Clinically, we often see many patients get bored after grabbing a lot of white dirt from their scalp. Most of these patients will have itchy scalp if they don't wash their hair for two or three days. After scratching, a lot of white dirt will remain on their fingers, and even the scalp will fall off with the naked eye.

The most common disease that causes this phenomenon in clinic is seborrheic dermatitis. The sebaceous glands of the scalp are developed and produce a lot of oil, so it has become a good place for seborrheic dermatitis. Nowadays, with the fast pace of life and the abundance of electronic products, a large number of people are nervous, and staying up late will lead to an increase in the secretion of oil by sebaceous glands, which will lead to or aggravate diseases. In addition, because there are microorganisms in nature, the head is exposed to the air and in direct contact with microorganisms, so the infection of fungi and so on has become a very important inducing or aggravating factor of this disease.

So, how can we alleviate the troubles caused by seborrheic dermatitis?

First of all, compound ketoconazole hair cream and selenium disulfide lotion can be used appropriately to inhibit sebaceous gland secretion and antifungal to relieve local symptoms. Secondly, ebastine and loratadine can be taken orally to relieve itching. The most noteworthy thing is that the diet must be light at ordinary times, and we must maintain a good work and rest, so as to restore the function of sebaceous glands to normal, fundamentally reduce the secretion of oil, and keep our scalp fresh at all times.

If you don't wash your hair for a day or two, your hair will start to get wet, oily and itchy. If you scratch it with your hands, there will be a layer of white dirt under your nails and an unpleasant smell.

This is the early symptom of seborrheic alopecia, which is mainly due to excessive sebum spillage from the scalp, plus dust in the air and oil secreted by the scalp. If not cleaned in time, white dirt can be deducted.

The early stage of seborrheic alopecia is accompanied by increased dandruff, greasy scalp and itching. Some of them are accompanied by symptoms of seborrheic dermatitis. If the patient does not pay attention to it in the early stage, the hair will gradually fall off, which will seriously cause baldness.

Seborrheic alopecia generally starts from the middle of the two frontal angles, forehead and top of the head, and then spreads to the whole top of the head, but there is not much hair loss around the head. If the symptoms of seborrheic alopecia are serious, the hair loss area becomes shiny and shiny, and the rest of the hair becomes soft and yellow.

What are the causes of seborrheic alopecia?

1. Androgen increases, and seborrheic alopecia is more common in men. It is found that there are too many androgens in men with seborrheic alopecia, mainly because the androgens secreted by testis enter the blood circulation and reach the scalp to form toxic substances to stimulate hair follicles, and the energy metabolism and protein metabolism of hair follicles are damaged, leading to hair loss.

2. The relationship between mites, that is, "tinea after eating, baldness after eating" (that is, seborrheic alopecia) and cephalomites has been confirmed by modern medicine. Metabolites of cephalomites can cause allergic reactions, and the entry and exit activities of cephalomites can carry pathogenic microorganisms, causing cell infiltration and fibrous tissue proliferation around hair follicles. Cephalmites can also bring bacteria on the scalp into the depths of hair follicles, causing inflammation, affecting the normal proliferation and fission of hair mother cells, and leading to hair occurrence.

3. Heredity: The genetic genes of seborrheic alopecia are dominant in men, and the pathogenic factors can be directly passed on from the previous generation to the next generation, so male seborrheic alopecia patients are more common.

4. With the increase of age, men aged 30-40 are more likely to suffer from seborrheic alopecia.

What about seborrheic alopecia?

1, using mild and non-irritating silicone oil shampoo, seborrheic alopecia scalp hair itself is fragile and can't stand stimulation, while the cleaning foaming agents used in the market are mostly soap-based shampoos such as sodium dodecyl sulfate, carnosic acid and lauric acid, or S-type shampoos such as sodium dodecyl sulfate and sodium dodecyl polyoxyethylene sulfate. Both shampoos have cleaning effects, but they are very irritating.

When seborrheic alopecia patients use this irritating shampoo, it will destroy the scalp oil balance, aggravate alopecia symptoms and even aggravate seborrheic dermatitis.

Silicone oil-free shampoo uses coconut glycoside instead of soap base such as sodium dodecyl sulfate and S shampoo. Coconut glycoside is extracted from coconut, which is mild and non-irritating and has good cleaning effect. Long-term use can gently care for scalp and hair and relieve seborrheic alopecia.

All organic substances are extracted from organic plants, and mineral oil, silicone oil and chemically synthesized harmful substances are not added, which has a quite good effect on hair care.

2, diet should be light, eat more minerals such as iron, calcium, zinc, vitamins A, B, C and foods containing more protein, such as fish, soybeans, eggs, lean meat rich in protein, seaweed rich in trace elements, shellfish rich in vitamins B2 and B6, spinach, asparagus, bananas, pig liver and so on. It is beneficial to protect hair and delay aging, and keeping the stool unobstructed is beneficial to the normal growth of hair.

3, avoid staying up late, smoking and drinking, alcohol and tobacco will affect the growth of hair.

4. For severe alopecia, 20g of Polygonum Multiflori Radix, 20g of Radix Puerariae12g, 0g of Radix Rehmanniae10g, Periostracum Cicadae, Flos Magnoliae, Radix Angelicae Sinensis, Herba Epimedii, Radix Arnebiae and Semen Cuscutae can be made into 500ml syrup, with 50ml each time three times a day.

Ye Fan's favorite hairstyle.

Too busy to take selfies on the road. You can't tell if my hair is oily from this angle.

Whenever there is a big occasion, Ye Fan always has the shape of a big wave, and this routine must be there.

Occasionally, I will wear a light makeup and return to straight hair, the standard college flower style!

It's not the first time to wear a wig, which shows that everyone has different requirements for hairstyles and pursues different patterns.

The goddess is sometimes lazy.

"Kangxi Comes" invited Fan Bingbing to record the program. In fact, there is an interesting connection. The host and Xiao S asked her how sloppy life can be. Sister Bing Bing's answer is very domineering!

I frowned. If I rest at home, I can not take a shower for many days or wash my face for three days. The explanation given by not washing your face is that naturally secreted oil is good for your skin. Please don't imitate oily skin and problem muscles here, you'd better clean them well!

At this time, Xiao S couldn't sit still. Just ask him not to wash his hair for three days. You know, Big S and Little S wash their hair every day. Big S revealed that he had to wash his hair every day when he published the book.

Honest and frank sister Bing Bing replied that no one, she will ~ I often will.

I also joked that because I don't wash my hair, my scalp will smell of oil. When the big black cow smells it, say you wash your hair. It can be seen that shampooing is not shampooing, shampooing is scalp washing, and hair care is hair care.

Comb your hair before washing your hair.

What do you think you should do before washing your hair? I think few people would think of combing their hair before washing their hair. In fact, as long as you comb your hair for one minute, you can promote blood circulation and remove the old waste residue on your scalp more effectively, which is better than washing your hair directly.

Many people's hair is dull, because repeated dyeing and perm leads to injury and sensitivity, so the scalp must be combed frequently.

Comb your hair from the scalp. There are many acupoints on your head. Stimulating this part more is also helpful for hair growth.

Yes, just put your hands there!

Shiatsu massage is more soothing.

Massage the back neck in a circular motion to completely relax the tense muscles.

Then press the sunken part in the middle with your fingers, which can better stimulate the acupoints.

It will be more effective to tilt your head back.

Cat claw scalp massage

Fingers are in the shape of cat's claws, so do the next massage.

Fingertips slide slowly from one side of the head to the top of the head. Do this action three times.

Then grab the hair and pull it up. With proper strength, this action will make the hair roots stronger and the hair healthier.

The best time to wash your hair is at night.

Shampoo needs foaming first, just like we wash our faces. We can make the foam more abundant with the help of foam net.

We can compare the foaming effect. The foam on the left is dense and the foam on the right is sparse, but the finer the foam, the better the scalp.

Many people like to wash their hair every morning. In fact, the best time to wash your hair is at night. It is best for your health to wash away the residue accumulated in a day before going to bed. 10 afternoon-before 2: 00 am, it is the vigorous period of producing old waste keratin.

Everyone has a correct concept of shampoo. Shampooing is not shampooing, but washing the scalp. Still try to rub the gaps between the hair and clean the hairline.

After wiping the scalp, leave it for 1-3 minutes before rinsing.

After washing off the foam, we will use conditioner. Different from the previous direct application method, we first pour the conditioner into water to dissolve, and then soak the hair ends.

This method can increase the luster of hair. When washing conditioner, the water temperature can be lowered a little, which can enhance the elasticity of hair.

Finally, when you blow your hair, you should blow hot air first, then cold air. Be sure to open your hair and let the temperature of the hair dryer bring it into your hair.

Now let's make a scalp comparison with the instrument.

After comparison, it was found that the grease and dandruff had disappeared, indicating that the correct shampoo method can make the scalp get better care. This way, even if you don't wash your hair often, you can keep your scalp fresh for about three days.

The scientific name of this kind of dirt is skin dirt.

Skin dirt refers to dirt attached to the skin, which contains keratinocytes that we naturally shed, oil secreted by the skin, microorganisms, sweat, dust and so on. The formation of white mud is because the main components are keratinocytes and oil.

Our scalp, like skin, will be protected by the stratum corneum, which is constantly changing, and the newly generated keratinocytes will replace the previous cells, so that the surface of the stratum corneum will fall off. This kind of shedding can be seen everywhere in life. In a family where the air is not too dirty, the white dust on the ground is actually mainly the dander we shed.

In order to make our skin waterproof, the human body will secrete a layer of sebum film on the skin surface, and these oils will also accumulate after a period of time, which will not only easily adhere to falling dander and dust, but also make these things stick together, thus forming a mud-like substance.

I'm KINOMOTO SAKURA, and I'm glad to answer this question. If you don't wash your hair for two or three days, your hair will not only be oily and itchy, but also have an odor. At this time, you will scratch your scalp and buckle white dirt. So what is white dirt?

What is the white dirt on the scalp? If you don't wash your hair for two or three days, the metabolism of the scalp will not stop, and then you will get oil and produce dandruff. In addition, the external dust will inevitably fall on your head, and the combination of these three forms the white dirt we see.

Small coup to reduce white dirt. It is almost impossible to completely wash off the white dirt at one time, and it can only be improved slowly through appropriate methods. Here are some tips.

Conclusion The above are some answers to the problem of white dirt based on my own experience, and some small improvement methods, hoping to help friends in need.

Dandruff, this season in autumn, is really dandruff. The weather is dry in autumn and the scalp is dry. Therefore, when washing your hair, don't apply conditioner to your scalp, which will clog pores and produce dandruff. It is best to buy silicone-free care. It is also good to comb your hair regularly before going to bed at night. Rubbing the scalp with a tooth comb can promote the blood circulation of the scalp and complete metabolism, thus achieving the effect of improving hair quality and promoting sleep, killing two birds with one stone.

It is best to wash your hair twice a week, and if you wash your hair at night, you must blow dry it. If you don't blow dry, you will have a headache the next day. If you wash your hair in the morning, dry it quickly. Never go out with your hair wet. Being blown by the cold wind can also cause headaches.

Furthermore, when blowing hair with a hair dryer, use cold air instead of hot air, which will damage the hair scales. The cold wind blows to close the hair scales without hurting the hair.

When you blow your hair, blow it from under the net.

The scalp also secretes oil, which is a mixture of oil, dust in the air and dead skin cells metabolized by the scalp.

Although washing your hair should not be frequent, you should not be too negligent. You can choose shampoo with strong oil control and cleaning ability. If there is more dandruff and grease on the scalp, it will be accompanied by unbearable itching and a lot of hair loss. It may be seborrheic dermatitis, so you can go to the drugstore to buy ketoconazole lotion to clean it. If it is serious, you need to see a dermatologist.

This is dandruff on the scalp, soaked in sweat and turned into dirt. Because the highest part of the human body is the top of the head, and heat is always lighter than cold, which means that hot air and water are always higher than cold, and the temperature of the scalp is also high, which is easy to turn dandruff into dirt. Adding sweat during fermentation will produce an unpleasant smell. It is impossible to clean it thoroughly, so that it will never be there, because people's skin often falls off. Add tiny dust. Will not fall off by itself under the cover of hair. Only frequent cleaning.

The white dirt on the head is of course dandruff. If you don't wash your hair for three days, you will feel uncomfortable. Your hair is oily and dandruff is more, especially in autumn. Therefore, most women must wash their hair every three days. After washing your hair, you'd better let it dry naturally. Don't use a hair dryer. Naturally dry hair is not easy to damage hair quality and dandruff, but it can be combed with a comb to stimulate the scalp and promote the blood circulation and metabolism of the scalp.

Many handsome guys and beautiful women think that if they don't wash their hair for two or three days, they will get white dirt on their heads, which is itchy. In fact, if it's summer and autumn or you're sweating all over, buckle something dirty from your head or something. If you buckle white dirt from your head in winter and spring, it is actually dandruff. Compared with men and women, men are mostly men with high androgen. After they enter the blood circulation, they produce toxic substances to stimulate scalp hair follicles, and then sebaceous glands secrete vigorously. Excessive sebum is mixed with dust in the air to produce dirt. In severe cases, seborrheic dermatitis is easy to occur, which stimulates scalp cells and nerve endings and produces itching. People can't help scratching. This requires us to choose a high-quality and gentle shampoo according to everyone's hair quality when cleaning our hair. Pay attention to drink less, don't eat spicy and exciting things, pay attention to a light diet, less oil and salt, stay up late less, keep a steady mind and work and rest on time.
