Answer

Alopecia areata can be classified according to its pattern, as follows:

  • Reticular - Hair loss is more extensive and the patches coalesce

  • Ophiasis - Hair loss is localized to the sides and lower back of the scalp

  • Sisaipho (ophiasis spelled backwards) - Hair loss spares the sides and back of the head

  • Alopecia totalis - 100% hair loss on the scalp

  • Alopecia universalis - Complete loss of hair on all hair-bearing areas
