Reasons for itchy scalp and how to treat it - Dr. Rasya Dixit
What to do if your head itches?
Severe itching of the scalp is terribly unpleasant, but it can be seen in both adults and children. Why does the head itch? The reasons for this uncomfortable symptom can lie in anything. Often they signal the presence of a strong allergic reaction, and even dermatological diseases. However, they can be very prosaic, especially if a person neglects hygiene standards and does not wash his head in a timely manner.
It also happens that the head itches and hair falls out. Such manifestations can signal the development of diffuse alopecia, which also has its own endogenous causes. It often happens that a woman experiencing similar symptoms is simply not suitable for the care products that she uses on a regular basis.
You will be surprised, but an allergic reaction can appear even to an irritant such as foam or styling gel!
It is even sadder when such alarming signs are associated with such an unpleasant disease as head lice, which, alas, is not at all uncommon even in our progressive times. Ultimately, itching can be the result of neurological disorders in the body.
Unfortunately, it is almost impossible to diagnose the exact cause of an itchy scalp. Since scabies can be associated with fundamentally different factors, only a competent and qualified trichologist can determine the true violation. And even he often needs the opinion of other narrowly focused specialists to make an objective verdict.
Differential diagnosis of the problem is almost impossible in an independent version, unless the reasons for the unpleasant phenomenon lie in the most banal violations of care on your part. But today we will give you some of the most common things that can be associated with your discomfort. How to understand why the head itches?
Causes of itchy head
If your scalp itches badly and for a long time, this is a good reason to be alarmed and consult a doctor. Typically, this symptom does not appear alone . Very often, excessively oily skin itches, and this phenomenon is caused by the occurrence of oily seborrhea. This disease requires adequate treatment, the course of which will be drawn up by a dermatologist or trichologist.
Often to these pReddish plaques are added to the appearance, which suddenly appear on the scalp. If the crusts come off, the wounds can get wet and make the patient even more uncomfortable. Despite the fact that all this seems scary, such symptoms occur in most people who visit a doctor for itchy skin.
When you have a severe itchy head, you probably frantically ponder all the possible causes of such a disorder. Before sounding the alarm and running to specialists, you should pay attention to the observance of hygiene standards. It does not necessarily accompany the trivial excess of sebum on the scalp.
The reason that if the head itches can be a bad habit of many ladies to wash their hair poorly after shampoo or conditioner. Think about what would happen to your skin if after every shower you did not rinse off the soap with water, but left it on your body. A sad picture, isn't it? But your scalp is no better and no worse - it also requires proper washing away from itself the remnants of aggressive household chemicals.
Make it a rule to rinse your hair with water until it becomes clean and transparent. While washing, massage the skin with your fingertips and gently shake the hair roots so that no washing products remain on them. Better yet, if you temporarily skip the standard shampoos altogether, and begin to clean your hair the old fashioned way - for example, using a chicken egg or laundry soap.
The most alarming and often objective suspicion of those who are faced with an unpleasant symptom is the presence of parasites, that is, lice.
Pediculosis really occurs today. It is especially common, as usual, in children's educational institutions. Therefore, if you have a school-age child, it is possible that he brought home the infection.
If the head itches, but there are no lice, this does not mean their exact absence - an incubation period is characteristic for this parasitic invasion.
And lice themselves are not the only parasites that your head may fall in love with. A fairly common cause of itching in this case is also demodectic disease, provoked by the Demodex mite, which lives in almost every feather pillow.
Internal causes of itchy head
Other causes of itchy scalp:
- Seborrhea. It can be oily and dry, and occurs due to a change in the structure of the sebaceous secretion in the pores. Usually, the skin peels off strongly and such an unpleasant phenomenon as dandruff appears. It should be noted that seborrhea often evolves into chronic seborrheic dermatitis, a rather complex disease, the quality of which can only be selected by a specialist. Therefore, if you have dandruff and with ethe head itches - it's time to seek professional help;
- Fungal lesions. Another common cause of itching, which requires complex drug treatment. If now you cannot go to a dermatologist or trichologist to pass a scraping for fungal culture, and the skin itches is almost unbearable, try using pharmacy products. Antifungal shampoos contain climbazole, pyroctonolamine, and zinc pyrithione, which can control the spread of infection. Tea tree essential oil is also a good home remedy. However, do not delay the amateur performance - in order to avoid complications, consult a doctor as soon as possible;
- Parasitic infestations. We have already talked about them, but we should once again urge you to contact a dermatologist if you have any suspicions about them. Please note that even if the lice are not yet visible, this does not mean that they are not. And when there are too many of them, therapy will be much less effective. It is also worth visiting an in-person consultation with a doctor if you think you have demodicosis. This condition is difficult to treat and very unpleasant, especially when it affects the face (which will certainly happen later if present).
Do not hesitate to visit your doctor with complaints of an itchy head. Alas, this phenomenon does not always indicate improper care. And any disease, as you know, tends to progress, and even modify into complicated forms.
Allergies and possible irritants in head itching
Allergy sufferers, by nature, often experience itchy skin after using a new and seemingly completely harmless remedy.
Allergic reactions on the scalp can be provoked by:
- New shampoo, conditioner, mask or any other care product;
- Hair dye, especially industrial household (non-professional);
- Detergent or laundry detergent used to clean bed linen;
- Styling products (varnish, foam, wax, gel);
- Leave-in serums, fluids and heat protection products.
If you suspect you have an undesirable reaction, which often happens when you change your cosmetics, try returning to the product you used before. If the itching subsides at the same time, you should discard the recently purchased products. If the past products did not fully satisfy you, and you have no desire to use them again, we advise you to buy a neutral baby shampoo that does not irritate the skin and does not interfere with the process of sebum secretion.
Please note that purchasing products that are not suitable for your hair type also run the risk of getting side effects of using them. This is especially true of those cosmetics that dryskin, being designed to care for very oily hair. If you dry out the skin and thin the hair at the root, itching will certainly occur without allergies.
Please note that allergies can be caused by paint that contains ammonia or hydrogen peroxide. If you paint without the help of a master at home, conduct an allergy test. This simple test involves first applying a drop of oxidizer to the delicate skin on the back of your wrist. If no reaction is observed within 15 minutes, feel free to use a dye.
Treat your skin responsibly and stay healthy!
