Dandruff (also called 'pityriasis<\/span> Capitis ") is a non-inflamed form of seborrheic dermatitis. Dandruff is presented as bran scaly<\/span> patches scattered inside hair<\/span>Carrier areas of the scalp.<\/p>\n<\/span>What causes seborrheic dermatitis?<\/span><\/h2>\nThe cause of seborrheic dermatitis is not fully understood. It is associated with proliferation<\/span> of various species of skin diner<\/span> Malassezia, in its yeast (nopathogen<\/span>) shape. Their metabolites<\/span> (like fatty acids oleic acid, malssezin and indole-3-carbaldehyde) can<\/span> cause a inflammatory<\/span> reaction. Differences in the skin barrier. lipid<\/span> Content and function can represent individual presentations.<\/p>\n<\/div>\n
<\/span>Who gets seborrheic dermatitis?<\/span><\/h2>\nInfantile seborrheic dermatitis affects infants younger than 3 months and usually resolves at 6-12 months of age.<\/p>\n
Seborrheic dermatitis in adults tends to start in late adolescence. Predominance<\/span> it is greater in young adults and the elderly. It is more common in men than in women.<\/p>\nThe following factors are sometimes associated with severe seborrheic dermatitis in adults:<\/p>\n

- Combination of oily and dry skin in the middle of the face<\/li>\n
- Poorly defined located<\/span> scaly or fuzzy patches scale<\/span> on the scalp<\/li>\n

<\/span>How is seborrheic dermatitis diagnosed?<\/span><\/h2>\nSeborrheic dermatitis is diagnosed by its clinical appearance and behavior. As the malassezia are a normal component of the skin flora, its presence in microscopy<\/span> skin scraping is not diagnostic.<\/p>\nSkin biopsy<\/span> It can be useful but is rarely indicated. Histological<\/span> The specific findings of seborrheic dermatitis are superficial. perivascular<\/span> and peripheral<\/span> inflammatory infiltrators<\/span>, psoriasiform<\/span><\/span> hyperplasia<\/span>and parakeratosis<\/span> around follicular<\/span> openings<\/p>\n<\/div>\n
<\/span>What is the treatment for seborrheic dermatitis?<\/span><\/h2>\nSeborrheic dermatitis treatment often involves several of the following options.<\/p>\n
\n- Keratolytics can be used to remove scale as needed, for example salicylic acid, lactic acid, urea, propylene glycol.<\/li>\n
- \nCurrent<\/span> Antifungal agents are applied to reduce malasezia, for example ketoconazole, cyclopirox shampoo and \/ or cream<\/span>. Be aware that some strains of Malassezia are resistant to azole antifungals. Try zinc pyrithione or selenium sulfide<\/li>\n
- Mild topical corticosteroids are prescribed for 1-3 weeks to reduce inflammation<\/span> of a acute<\/span> flare<\/li>\n
- Topical calcineurin inhibitors (pimecrolimus cream, tacrolimus ointment<\/span>) are indicated if topical corticosteroids are often needed as they have fewer adverse effects on facial skin.<\/li>\n<\/ul>\n
In resistant cases in adults, oral itraconazole, tetracycline antibiotics, or phototherapy may be recommended. Low-dose oral isotretinoin has also been shown to be effective for severe or moderate seborrheic dermatitis.<\/p>\n
<\/span>Scalp treatment<\/span><\/h3>\n\n- Medicinal shampoos containing ketoconazole, cyclopirox, selenium sulfide, zinc pyrithione, coal tar, and salicylic acid are used twice a week for at least a month and, if necessary, indefinitely.<\/li>\n
- \n
Steroid applications to the scalp reduce itching and should be applied daily for a few days from time to time.<\/li>\n
- \n
Calcineurin inhibitors, such as tacrolimus, can be used as alternatives to steroids.<\/li>\n
- \n
Coal tar cream can be applied to flaking areas and removed several hours later with shampoo.<\/li>\n
- Combination therapy is often advisable.<\/li>\n<\/ul>\n
<\/span>Face, ears, chest and back<\/span><\/h3>\n\n- Clean the affected skin thoroughly once or twice a day with a soap-free cleanser.<\/li>\n
- Apply ketoconazole or cyclopirox cream once a day for 2 to 4 weeks, repeat as needed.<\/li>\n
- Hydrocortisone cream can also be used, applied up to twice a day for 1 to 2 weeks. Occasionally, a more powerful topical steroid may be prescribed.<\/li>\n
- Topical calcineurin inhibitors such as pimecrolimus cream or tacrolimus ointment can be used in place of topical steroids.<\/li>\n
- A variety of herbal remedies are commonly used, but their effectiveness<\/span> It is uncertain.<\/li>\n<\/ul>\n
<\/span>Management in infants<\/span><\/h3>\nRegular washing of the scalp with baby shampoo or aqueous cream is followed by a gentle brushing to clean the scales.<\/p>\n
\n- White petroleum jelly can be helpful. <\/li>\n

Topical antifungals are often prescribed, depending on the extent of the rash.<\/li>\n<\/ul>\n<\/section>","protected":false},"excerpt":{"rendered":"
