Ophiasis

Ophiasis[1] is a form of alopecia areata characterized by the loss of hair in the shape of a wave at the circumference of the head.[2]

It gets its name from "ophis", which is the Greek word for snake, because of the apparent similarity to a snake-shape and the pattern of hair loss.[3]

The term "sisaipho" is used to characterize the inverse pattern. Sisaipho is, almost, the reverse spelling of ophiasis.[4] It is also called "ophiasis inversus".[5]

This form of hair loss "...targets the body's own hair follicles, resulting in hair loss..." and although the immune system could be attacking hair follicle melanocytes, dermal papilla cells, and keratinocytes,” the foundational cause of this disease is yet to be confirmed.[6]

Pattern of hair loss

This is one among many types of patterns of hair loss, “in which they have band-link hair loss across the occiput.”[7] Hair loss can take the form of patches of hair being removed and there can also be spontaneous regrowth as well.[7]

Duration of hair loss

Ophiasis hair loss is one form in which the hair loss can further deteriorate and can extend “for more than a year.”[7]

gollark: > and rust's syntax is a horrible tradeoff :PWhy? It seems pretty C-ish. I quite like it.
gollark: > there are tools that prevent you from doing unsafe thingsThey don't seem to be hugely *good* at it, or at least aren't deployed enough, given the massive frequency of memory-related bugs in C projects.
gollark: People make mistakes and you can't just tell them not to. Even SQLite, which is ridiculously extensively tested and has very skilled developers, has bugs sometimes. If a language can prevent significant classes of mistake without horrible tradeoffs, that is a good thing to have.
gollark: But seriously, "just don't do unsafe things and it's fine" is such a bad argument.
gollark: Actually mostly.
