Hair relaxing and permanent waving are two procedures that can be damaging to hair and should only be used on a limited basis. While hair relaxing can weaken hair, it also can actually facilitate hair length in
patients with kinky hair since the hair is less likely to break when combed. The relaxing procedure straightens the hair and makes it easier to groom. However, the grooming should be done gently to avoid hair
fracture.
When using permanent waving, the curls should be as loose as possible with the interval between procedures being as long as possible. For patients with damaged hair, the perming solution should be weak and left in
contact with the hair for as short a period as possible. If you notice that your hair is becoming brittle or looking dull or damaged, you should consult your dermatologist immediately to determine the cause and how
to treat it.
Repairing damaged hair takes time, and usually involves growing healthy hair to replace the damaged hair. The sooner you address any problem, the sooner you'll notice results.
