Hello everyone. I am almost 21-years-old male and and I think I have scalp plaques in my hair. I've seen some pictures of it on google and people's heads are full of that white stuff. However, mine don't show that much. I just have itch in my hair and when I itch my head, hair pulls out and there is a white looking small head at the end of that fallen hair's root. I've searched it online and it showed as scalp psoriasis. I am not sure if I have scalp psoriasis as (again) the pictures of others show their the whole head full of it and I only have at the end on my hair's root. Do I really have scalp psoriasis????? I have not checked with dermatologist yet as I don't have insurance and without insurance, they're quite expensive around the zip code I live in. All of Your posts will be very helpful and I will read all answers throughly. Thanks in advance to everyone.
