In this

section is wound or -wrapped around a small di

required depends upon'the ease or difliculty with

approximately thirty rods are required to wave
the average head. The curling rods are provided
with a metal spring, or elastic band which can
be snapped over the curled hairto maintain the
hair in the curled state and to retain the rods in
suspended position about the scalp. After all the

Figure 4 is an isometric View of the rubber
bundle of hair curled into a mass several inches
long and approximately an inch in diameter, it
is apparent that the normal methods of moisten- `
ing the mass externally do not permit penetration
oi the solution to the inner layer of hair strands.
Consequently, the inner hair curls do not receive '
a permanent set and as these inner curls are the
extremities of the' hair the completed job is not
at all pleasing to the customer. Experienced op
