In the second step, the separated bonds are reformed using an oxidizing agent. Here, the hair is set according to how it was shaped by the rods. The hair’s new shape then becomes permanent with the application of the oxidizing agent, or neutralizer. The hair’s original cohesion is restored, but now in a new form.
There is a wide range of perming products on the market. The two basic types are fluid and foam.
The choice of a waving lotion is dependant upon two factors.
One, the desired appearance of the waves:
- Soft (light) waves
- Medium waves
- Strong to extra strong waves
The other criteria is the hair type:
- normal hair
- fine hair
- damaged, colored hair
What should one consider when perming hair?
The most important requirement for a good perm is a good haircut. Damaged hair should only be treated with a mild waving lotion; fine, oily hair requires a stronger waving agent. For colored hair, an acid perm is recommended. However, it is important to keep in mind that hair should be permed no less than two weeks after coloring or blonding.
A perm lasts generally for one to four months, depending upon hair length, the choice of waving lotion and rods, and the amount of time the agent is left upon the hair.
