The hair's wave pattern is different from the other elements of hair
analysis because its classifications have no reference to the health of the
hair. Any of the wave pattern types can be found in healthy hair.

The classifications for wave pattern are straight, curly, very curly, and
coiled. Hair with absolutely no wave in its length is straight hair. Straight
hair can be coarse, normal or fine. Curly hair has wave to it. A curly hair
strand will form a distinct 'C' shape when short and an 'S' when longer.
Very curly hair will make an 'S' when short and a repetitive wave when
allowed to grow out. Very curly hair tends to be 'bushy' when worn long.
Coiled hair strands do just that - they coil in spirals as they grow out from
the scalp. The coils can be very tiny and give a kinked look to the hair,
or they may be finger-sized ringlets.
