. Many people will face such a problem. The scalp is very itchy. If you scratch it with your hand, you will make a lot of dandruff and fall on people’s collars. It greatly affects a person’s appearance and gives people a feeling of sloppiness. Many people are helpless and don’t know how to solve it. Dandruff is very serious. What if it’s all over your head? There are mainly several ways to solve this problem. Come with me.
Many people attribute dandruff to & ldquo; Malassezia & rdquo;, From the root, it’s OK, but to be honest, most people have Malassezia on the surface of the skin (including the scalp), but not everyone has dandruff. Therefore, it’s better to analyze it from another perspective than Malassezia.
1. Congenital heredity
most of these heredity are caused by sex hormones (for example, high androgen leads to excessive oil secretion, and some male hair loss is also caused by androgen). When the androgen in the body is high, the skin oil glands will secrete more oil than ordinary people, These sebum became the best fertilizer for Malassezia, allowing Malassezia to grow in large numbers. At the same time, Malassezia will produce a large number of free fatty acids in the process of consuming sebum. These free fatty acids will decompose the sebum membrane on the surface of the skin, destroy the skin barrier, and lead to a vicious cycle of scalp ecosystem.
2. The day after tomorrow
. It’s most appropriate to take my old aunt as an example. In fact, I have dry skin and am not easy to grow dandruff, but I used to love making my hair, dyeing and ironing once a few months, listening to the praise of the hair salon, and making baked oil and water film regularly. Hair dyes and perms contain a lot of ammonia, hydrogen peroxide, hydroquinone and resorcinol (yes, they are familiar whitening ingredients, but the dose is different and the comparability is not great). They are particularly unfriendly to the wound and are easy to stimulate the skin. If you dye your hair after scratching your hair, it will really make your scalp tingle and numb. In addition, don’t be misled by the business that you often bake oil to make a water film is good for your hair. Most hair film products should avoid contacting the scalp, because these products contain a lot of silicone oil, mineral oil and other closed better emollients. For the scalp that is often prone to oil and sweat, it is easy to stuffy acne if you use the hair film to contact the scalp for a long time, It is easier to aggravate scalp itching and dandruff. OK, let’s go back to the theme. Often do it indiscriminately. Long term use of highly irritating products can easily damage the scalp skin barrier, lead to skin lesions and eventually form dandruff.
3. Psoriasis
streptococcal psoriasis looks like ordinary dandruff, but the pathogenesis is different. Psoriasis is mainly caused by Streptococcus aureus, and there will be dandruff not only on the scalp, but also on the skin joints of the body. It is also easy to be accompanied by redness and itching. There are many causes of psoriasis, such as Congenital heredity, acquired immune abnormalities, hormones in the body, irregular work, rest and diet, etc. The above three reasons will lead to the damage of the scalp skin barrier. After the damage, the skin will secrete more oil to protect the scalp. However, these oil are once again consumed by Streptococcus aureus and Malassezia and become free fatty acids, which further aggravates the damage of the skin barrier, and the cortex that has not been repaired will slowly fall off and become dandruff. Therefore, why is dandruff? Those white unknown things are not harmful, but our own serious & ldquo; Immature scalp & rdquo;.
Treatment
good. After finishing the above common causes of dandruff, let’s take a look at the treatment.
1. Drug treatment
whether Streptococcus aureus or Malassezia are actually a kind of fungi. The effective method for fungi is to use some external & ldquo; Ketoconazole & rdquo& ldquo; Vulcanization drying & rdquo& ldquo; Salicylic acid& ldquo; Coal tar & rdquo; And other products. These medicinal lotions are better than many commonly used shampoos for people with frequent dandruff and scalp itching, and the price is not expensive, about 30 yuan. The disadvantages are also obvious, because it is medicinal, the effect is good, but the experience is very poor. Many have a chemical smell, and the hair is dry after washing. In fact, there is one called Caile ketoconazole lotion. I remember it is a pink liquid, and the taste is not bad, but… It’s useless. I don’t recommend buying it. Personally, I think the effect of curing and drying is better than ketoconazole. However, this is my personal experience. I haven’t found any papers comparing the actual data on HowNet and Jiufang. If there is, or other small partners understand it, you are very welcome to add it under the message.
2. Oral.
recommended for oral administration is compound vitamin B. when I read two books, cosmetic dermatology and clinical dermatology, I once read that vitamin B group has significant effects on avoiding excessive skin keratosis and preventing pellagra. In addition, vitamin B group can also regulate excessive skin oil secretion and help repair the skin barrier. When you buy multivitamin B, just go to the drugstore and buy a bottle for a few yuan. Don’t ask about the brand. The brand is not selected, ha, but this should be taken orally for a long time. It won’t work if you use it for only a few days. If vitamin B, nuts and other cereals are not good for your health, you can also worry about taking them orally（ In fact, don’t worry too much. Vitamin B is water-soluble and can be accompanied by body fluid excretion).
3. Daily shampoo.
daily shampoo and hair care products are suitable for those with mild dandruff and used for dandruff removal and cleaning. This kind of shampoo should not use ordinary shampoo as far as possible. It is recommended to use dandruff removal shampoo. This kind of shampoo contains dandruff removal factor. If the shampoo we use, the foam is not full enough and delicate, it will easily damage the skin. Finally, I would like to emphasize that in the selection of shampoo and care products, for daily care, remember to choose shampoo with anti dandruff effect, many of which are featured & ldquo; Silicone free shampoo & rdquo; In fact, it’s not that silicone oil-free products are bad, but that they are not targeted. Of course, if dandruff is serious, it is recommended to see a doctor in the dermatology department of the hospital, and the products used are also recommended to be mainly medicinal lotions. Ha ~ ~ shampoo focuses on daily cleaning, and serious dandruff actually belongs to the category of skin diseases. How can skin diseases be treated with shampoo? 4. Daily work and rest. One is to smoke and drink less. Smoking and drinking is really bad for the skin. If the skin is bad, it will certainly affect our scalp. The second is to go to bed early. The head skin is also an organ. If you don’t rest well, it is easy to have endocrine disorders and oil. The third is to eat less high sugar and spicy, especially high sugar.
Dandruff is very serious. How can I do it all over my head?
1. Correct Shampoo
everyone has a certain amount of dandruff on their head, but there is a large amount. These dandruff may be the normal secretion of oil debris or the residue of shampoo on the hair. If the symptoms of dandruff are very mild, there is generally no need for special treatment. However, if dandruff is very serious, you need to wash your hair with a special dandruff shampoo.
if there is dandruff, when choosing shampoo, you should choose shampoo containing selenium and cadmium, or some pure plant Chinese herbal medicine is also very useful. You can use it for three weeks to observe the dandruff removal. If there is still a lot of dandruff, you should go to the dermatology department for diagnosis and treatment. Try not to blindly increase the number of shampoo because of the increase of dandruff, and do not blindly use dandruff removing drugs.
2. Pay more attention to your diet
if dandruff increases recently, you should reflect on whether you have been too indulgent in your diet recently and eat more spicy and stimulating food. In order to improve the increase of dandruff, you should eat more alkaline foods, such as kelp, milk, vegetables, fruits, etc. To temporarily stay away from those spicy and greasy food, so as not to stimulate the scalp and make the hair have more dandruff.
3 Frequently do scalp massage
there is too much dandruff on the head. You can also take scalp massage to alleviate this symptom. Because regular massage of the scalp will accelerate the blood circulation and metabolism of the scalp, massage the scalp smoothly, and make the hair follicles, sebaceous glands and other parts of the scalp run more normally. Because if the hair follicles are blocked, it is very easy to produce dandruff and acne on the scalp.
4. Relieving pressure
a lot of dandruff is caused by increased pressure, which is why people facing exams usually have a head of dandruff. If you want to improve this situation or prevent dandruff, you must learn to relieve pressure, release negative emotions and relieve tension.
having a head of dandruff is very annoying. Every time you scratch your scalp, it’s like snow. In addition, dandruff falls on your collar, which also greatly affects a person’s image. To solve this problem, we must first find out what causes dandruff, and then take symptomatic measures. Otherwise, it will be completely different, so that the problem can not be fundamentally solved.
