Hair perming is a form of hair curling or waving; its a hair treatment using chemicals
that can be used to add curl and body to your hair.The perming process consists of breaking the hair structure which has disulphide bonds which can be broken by putting the chemicals on hairs. This is done in two parts, first is wrapping the hairs in to some curling accessories and then applying that chemical for restructuring the hairs. Ammonium thioglycolate is basic constituent of perming lotion and a neutralizer is applied after the curling lotion is being rinsed away and hairs being given physical shape with the help of curling rods or other accessories. Neutralizing process actually causes most of the damage to the hairs so proper care should be taken while its application.

There are many disadvantages of hair perming. First and foremost is excessive dryness. Dandruff is one major side effect. Allergies to scalp may also develop.
Extra care needed for permed hairs;
Use special conditioner for perked hairs after every shampoo.
After hair wash dont use towel instead let it dry itself as towel turban will not let hairs to attain their actual curls when being removed as hairs get tangled up.
