My experience

Hi I noticed the red, flaky, crusty patches of skin on my head in october. since then i would itch the psoriasis off and then it would appear again and id itch it off again. sometimes they would come out red and my head would bleed slightly but today after i went to the haridressers my sister said to me your head is really red have you been itching it or something and i didnt reply but i got her to take a picture of it and there was this big patch of psoriasis and it was red. im wondering if i should go see a doctor?
