because it causesred bumpy skin which is noticeable
I just read that it said that a healthy person's dead skin cells can't be seen with the naked eye and dandruff is mildly higher than dry scalp so that leaves Psoriasis.
Because psoriasis is chronic and it causes overproduction of skin cells they're going to accumulate and become noticable.
Because skin cells on the scalp, replicate at a much faster rate, usually every 3-4 days, also it's chronic.
because it can affect other areas of the body not just the scalp. The flakes are also larger.
Because it is very noticeable if showing signs of symptoms--super unattractive, and very serious autoimmune disease
has more damage in the skin is is spread throughout the body.
