Dryness, seborrheic dermatitis, psoriasis, contact reactions to cosmetic products, and fungal infection require different management. Changing shampoo without a diagnosis may temporarily reduce visible flakes without addressing the cause.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Symptoms may worsen in autumn because of the start of the heating season, more frequent use of hats, temperature changes, and changes in cleansing habits. This may become more noticeable while preparing for winter, but seasonality alone does not establish a diagnosis. Flaking accompanied by itching, inflammation, or hair loss requires professional assessment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Clinical Differences Between Dry Scalp and Dandruff<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Feature<\/strong><\/td><td><strong>Dry Scalp<\/strong><\/td><td><strong>Dandruff and Seborrheic Dermatitis<\/strong><\/td><\/tr><tr><td>Appearance of flakes<\/td><td>Usually small and dry<\/td><td>May be larger, white, or yellowish<\/td><\/tr><tr><td>Sebum<\/td><td>The scalp often feels lipid-deficient<\/td><td>Oiliness is frequently present<\/td><\/tr><tr><td>Redness<\/td><td>May be absent<\/td><td>Inflammation and itching may occur<\/td><\/tr><tr><td>Other areas<\/td><td>Symptoms are usually limited to dryness<\/td><td>Changes may appear around the eyebrows, behind the ears, and beside the nose<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This comparison helps patients describe their symptoms but does not replace diagnosis. Psoriatic plaques, for example, may be thick and extend beyond the hairline, while contact dermatitis often appears after hair coloring or the introduction of a new product.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Why Does the Scalp Begin to Flake?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">With simple dryness, the barrier becomes impaired, transepidermal water loss increases, and the scalp feels tight. Very hot water, frequent harsh cleansing, and unsuitable keratolytic products may aggravate the problem.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Seborrheic dermatitis is associated with sebaceous gland activity, an individual inflammatory response, and Malassezia yeast. It is a chronic, relapsing condition and cannot be explained simply by \u201cdirty skin\u201d or infrequent hair washing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Other possible causes include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>scalp psoriasis;<\/li>\n\n\n\n<li>atopic or contact dermatitis;<\/li>\n\n\n\n<li>fungal infection;<\/li>\n\n\n\n<li>a reaction to hair dye, styling products, or a medicated product;<\/li>\n\n\n\n<li>accumulation of heavy cosmetic residue;<\/li>\n\n\n\n<li>scratching and mechanical irritation.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How Is the Scalp Assessed by a Trichologist?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The physician evaluates the type of scale, distribution of inflammation, condition of the hair shafts, and presence of hair loss. Trichoscopy provides a magnified view of the scalp and follicular openings. Microscopy or laboratory testing may be required if infection is suspected.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before the consultation, it is useful to recall when the symptoms began, whether products were changed, whether the hair was colored, and whether similar areas are present on the face or body. The scalp should not be aggressively cleansed immediately before the examination because this may temporarily alter the clinical picture.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Scalp Support During Treatment<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The treatment plan is based on the diagnosis. For seborrheic dermatitis, the physician may prescribe antifungal or anti-inflammatory treatment. Dryness usually requires gentler cleansing and barrier restoration. Psoriasis requires a separate medical protocol.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Professional cosmetic products are used as supportive measures rather than universal treatment. For example, <a href=\"https:\/\/www.skinaura.am\/product\/dsd-1-3\/\" rel=\"nofollow noopener\" target=\"_blank\">DSD De Luxe Peeling 1.3<\/a> is designed to cleanse the scalp, but its use should first be discussed with a specialist when there is active inflammation, excoriation, or no established diagnosis.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Mistakes That Maintain Scalp Irritation<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A common mistake is attempting to scrape away every scale. Intensive scrubs, fingernails, and hard brushes damage the skin and intensify inflammation. Another mistake is using several medicated shampoos and acid-based products at the same time, which makes tolerability difficult to assess.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Oils should also not be applied to inflamed skin without medical advice. They may provide a temporary feeling of softness but do not treat seborrheic dermatitis and may interfere with the tolerability of other products.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>When Is a Follow-Up Examination Needed?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A repeat consultation is needed if itching and redness increase or if painful crusts, weeping, pustules, or localized hair breakage appear. Rapidly enlarging lesions and signs of infection require prompt attention.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In chronic seborrheic dermatitis, the goal is not to promise permanent elimination of dandruff but to control the condition and reduce the frequency of flare-ups. The physician adjusts the maintenance regimen according to the skin response and season.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Why Does Treatment Depend on the Diagnosis?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Confirmed seborrheic dermatitis may be managed with antifungal shampoos, keratolytic ingredients, and short courses of anti-inflammatory medication. Frequency and duration depend on severity. Continuous use of a medicated product without monitoring may cause additional dryness and irritation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the physician finds signs of a contact reaction, the suspected product should be stopped without immediately replacing it with several new ones. Psoriasis requires assessment of disease extent and other body areas. Fungal infection may require systemic medication, so cosmetic products should not delay medical evaluation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Book a Trichology Consultation<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Medest provides diagnostic assessment of scalp conditions and individualized treatment planning. <a href=\"https:\/\/www.medest.am\/en\/services\/scalp-treatment\/\">Book a scalp consultation<\/a> if flaking recurs, is accompanied by itching, or does not improve after changing products.<\/p>\n","protected":false},"featured_media":0,"template":"","service_cat":[],"reason_cat":[220],"class_list":["post-16513","reason","type-reason","status-publish","hentry","reason_cat-hair-en"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.medest.am\/en\/wp-json\/wp\/v2\/reason\/16513","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.medest.am\/en\/wp-json\/wp\/v2\/reason"}],"about":[{"href":"https:\/\/www.medest.am\/en\/wp-json\/wp\/v2\/types\/reason"}],"version-history":[{"count":1,"href":"https:\/\/www.medest.am\/en\/wp-json\/wp\/v2\/reason\/16513\/revisions"}],"predecessor-version":[{"id":16517,"href":"https:\/\/www.medest.am\/en\/wp-json\/wp\/v2\/reason\/16513\/revisions\/16517"}],"wp:attachment":[{"href":"https:\/\/www.medest.am\/en\/wp-json\/wp\/v2\/media?parent=16513"}],"wp:term":[{"taxonomy":"service_cat","embeddable":true,"href":"https:\/\/www.medest.am\/en\/wp-json\/wp\/v2\/service_cat?post=16513"},{"taxonomy":"reason_cat","embeddable":true,"href":"https:\/\/www.medest.am\/en\/wp-json\/wp\/v2\/reason_cat?post=16513"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
