There is currently no definitive answer to this question. Trichologists and dermatologists hold different views:
- Seborrhea (seborrheic dermatitis) may be the cause of deposition;
- On the contrary, hair loss leads to the development of seborrhea (seborrheic dermatitis);
- the cause of hair loss is the same as the cause of seborrhea (seborrheic dermatitis): hormonal disorders, stress, etc.
Logically, a perfectlу healthy person's hair is unlikely to fit. But such examples are not known to medicine - if you take any medical card, then a person, whose doctors did not find anything that could be treated, will be in the column "state" - "almost healthy". There are no healthy people.
As for completely delusional assumptions about leukocytes and other things - people live with both chronic tonsillitis and worm infections almost all their lives, and most of them know nothing about any problems with hair.
I also have doubts about the qualifications of the doctor - ah, it turns out that leukocytes now live "in the head".
And I thought they were blood cells, which are carried by blood flow throughout the body. Or are leukocytes now only attacking hair follicles?
In addition, the list of your doctor's assumptions about the causes of loss can be continued indefinitely: or perhaps that the loss is associated with the state of the gastrointestinal tract, and perhaps - with frequent colds, and perhaps - with solar eclipses, and perhaps - the angle of inclination of the Earth's axis ....
Unfortunately, there can be no universal means here - someone helps one thing, someone else. So we have to act by the "pump" method, relying, if possible, on the real feedback of other people to have at least some statistics in our hands.
In conclusion, I would like to note that problems with the scalp can exist "by themselves" as well as "neighboring" with both reactive and chronic (androgenetic alopecia).
Also, the list of possible problems is not limited to seborrhea and seborrheic dermatitis.
Corticosteroids are not toys and can lead to very unpleasant consequences, especially those used "for nothing".
To select the right treatment, you need an accurate diagnosis, for an accurate diagnosis - the correct diagnosis. In cases of problems with the scalp, this may be the case:
- -Dermatoscopy is a hardware diagnostic method that allows a visual assessment of pathologically altered skin foci under multiple magnification of optical or digital dermatoscopy;
- -Skin pH-meter - Determination of acid-alkaline balance on the epidermis surface using pH-meters, glass electrodes or colorimetric indicators. The method is based on the fact that the pH of the skin normally ranges from 4.5 to 5.5, changes in the acidic direction in psoriasis, in the alkaline - in alkaline - in allergic dermatitis, has a slightly acidic reaction in fungal lesions (up to 6) and eczema (up to 6.5), shifts to a neutral reaction in dry skin (up to 7);
- -Scraping on pathogenic fungi from the skin - fence of epidermal scales from the affected area for microscopic examination. Epithelial scraping allows you to differentiate dermatomycosis from non-inflammatory skin lesions in the laboratory;
- Luminescent diagnostics - method of hardware diagnostics of mycoses, dermatoses, vitiligo, etc. with the help of ultraviolet lamp with filter - Wood lamp. The method is based on the fact that healthy and affected skin, scalp, nails under the influence of Wood lamp have different ability to fluorescence;
- other methods.
Do not hesitate to ask your doctor about the signs of diagnosis and what are the figures of the effectiveness of the treatment of those drugs that he prescribes to you!
When the reaction is like "I'm clear without diagnosis," "Who is the doctor here - you or me, here's the end of medical school, then we'll talk", "The drug is effective - here's a pamphlet for you to read", as well as in case of indiscriminate mumbling in response to your questions, I recommend you to clean up, because in front of you:
1 variant - a complete prostitute in the profession;
Option 2 - a doctor who does not care about your problem, including the fact that it can be exacerbated by the "treatment";
Option 3 is a doctor whose job is only to give you a specific drug on which he or she has a percentage.
A competent doctor, although sarcastic or irritated about a curious and/or skeptical patient, will ALWAYS tell you what the problem and treatment is, how it was diagnosed and what to expect from the start of therapy, and what to expect from the start of treatment, and how to replace expensive prescription medications if the patient is unable to spend so much money.
That's all.
