The end results were frizzy curls that were unmanageable and difficult to maintain.The cold wave was then introduced in the 1940s. The cold wave is basically what the modern perm treatment is today. Since the heat used in a cold wave can easily be regulated, the hair can now be curled closer to the scalp using this treatment.In a perm treatment, hair is washed and wound to curlers or curling rods to set.
