You are describing the typical presentation and distribution of seborrheic dermatitis (dandruff).



The flakes are different from psoriasis - it is more yellowish and oily. Psoriasis scales are silvery white on a thick red base.



As u can see, seborrheic dermatitis lesions on the scalp stays on the scalp. It does not exceed the hairline whereas psoriasis does. (picture below)

Psoriasis lesions also typically appears on the elbows and knees. They also get pitting in the nails.



Seborrheic dermatitis has elements of eczema + yeast infection. So, steroid cream and anti-fungal shampoo should help deal with it.
