Do disguises that cover your head or your face make you less likely or be less quickly detected?

I asked this question, because I remember (might be wrong though) that in Hitman: Blood Money, NPCs could be on the lookout for a "bald man", depending on certain player actions reported by a witness. An alert message will pop-up saying something to that effect. This makes the bald Agent 47 more likely to be detected by the now more alerted guards/hostiles if he's wearing clothes that expose his head, even if disguised. I'm wondering if Hitman: Absolution has a similar game mechanic.

I'm also wondering if face-covering disguises can make 47 be less likely or be less quickly detected. Even with the same type of disguises, one could have a head or face-covering version, while another one could have 47's head fully exposed.
