Answer

A reticular pattern occurs when hair loss is more extensive and the patches coalesce. An ophiasis pattern occurs when the hair loss is localized to the sides and lower back of the scalp (see image below).

Conversely, sisaipho (ophiasis spelled backwards) pattern occurs when hair loss spares the sides and back of the head (see image below).
