What Causes Redness On Scalp While Suffering From Seborrheic Dermatitis?
Not folliculitis decalvans
Detailed Answer:
Hello. Thank you for writing to us
I am dr.kakkar (dermatologist). I have gone through your query and I have also reviewed the image.
I can see erythema of scalp. You difinitely seem to have seborrheic dermatitis.
The line of hair growing in different direction is absolutely a normal thing and is part of natural whorl of hair that forms at the vertex of scalp.
Folliculitis decalvans is a deeper form of folliculitis which is also associated with a cicatricial/ scarring alopecia whereas I don't see any folliculitis or scarring in this image. I don't think you have folliculitis decalvans. You just have plain seborrheic dermatitis which is characterized by erythema and scaling of scalp.

Ketoconazole shampoo and topical steroid preparation

Hi. Thank you. I have reviewed the image.
This is part of seborrheic dermatitis. Redness is more along this patch but I can see that there is diffuse redness elsewhere as well.
I suggest you to use a ketoconazole based shampoo e.g Nizral shampoo, every alternate days. In addition I suggest you to use a topical steroid cream or lotion e.g triamcinolone acetonide 0.1% cream or mometasone furoate 0.1% lotion, once daily at night, on scalp skin, for 2 weeks. Topical steroids are antiinflammatory and vasocontrictive in action and would reduce redness and scaling of seborrheic dermatitis.
