- What are your symptoms and when you first noticed them?
- Do you have these symptoms for the first time or did you have them before?
- How serious are the symptoms, whether they are at all times the same or worsen / improve over time?
- Did you use certain creams, gels and shampoos, and how often?
- Does it seem to help you a little help?

Tests and diagnosis

A doctor can scrape skin cells facial skin for examination (biopsy) to rule out some skin inflammation with symptoms similar to seborrheic dermatitis, such as:

1. Psoriasis - this disorder also causes dandruff and red skin covered with dandruff and flakes. In psoriasis, you will usually have more flakes, and they will be silver-white in color.
2. Atopic dermatitis (eczema) - causes itchy, inflamed skin in the folds of the elbows, back and knees or on the front of the neck.
3. Rosacea - usually occurs on the face and there is actually very little flakes. It is manifested by redness in the cheek, with the expansion of small blood vessels, and sometimes the appearance of purulent "pimples". Such a change in the skin of the face is often accompanied by symptoms such as itching, burning and tightness. The skin is very easy to redden when the temperature changes.

Shampoos, creams and lotions - treatments for the treatment of seborrheic dermatitis:

- Creams, lotions or shampoos that control inflammation - hydrocortisone, fluocinolone or desonide corticosteroids can be applied to the skin or other affected areas. Effective and easy to use, but if used a few weeks or months without interruption, can cause side effects, such as thinning of the skin or the appearance of lines on the skin.

- Antifungal shampoo with stronger medications: recommended is to wash your hair twice per day with medical shampoo

- Antifungal medications that are taken as pills - your doctor may recommend anti-fungal medication Terbinafine (Lamisil). This option is not used often because it can cause serious side effects, such as allergic reactions and liver problems.

- Medications that affect your immune system - not the first choice of treatment because of possible increased risk of cancer. In addition, it cost more than mild corticosteroid ones.

- Cream or gel that fights bacteria - can be applied in the form of Metronidazole cream or gel once or twice per day.

- Light therapy and medication - this treatment combines psoralen with light therapy (photochemotherapy). Involves taking goods sensitizing medication (psoralen) before exposure to UVA light. UVA light penetrates deeper into the skin than UVB light, and psoralen makes the skin more reactive to exposure to UVA light. This more aggressive treatment consistently improves skin condition and is often used in severe cases of psoriasis.

Using gels, creams, shampoos based on sulfur, salicylic acid, selenium sulfide, zinc pyrithione, and antimycotic agents.
