How would you select the type of perm to be used for different hair types?
When choosing a perm style, consider the texture and length of your hair. Acid-balanced and alkaline perm solutions are used on different hair textures to create body and curl while moisturizing and relaxing the hair shaft. Hair length usually determines which perm rods will be used to create a curl or body wave.

Ammonium thioglycolate
Ammonium thioglycolate, also known as perm salt, is the salt of thioglycolic acid and ammonia. It has the formula HSCH2CO2NH4 and has use in perming hair.
What are the two types of perm lotion?
There are two types of perms, one step perms or single actions perms and two step perms or dual action perms. The active chemical found in most perm lotions is ammonium thioglycolate. Ammonium thioglycolate is the active chemical found in most perm lotions.

What happens if you put neutralizer on before perm solution?
Neutralizer does just that, neutralizes a solution. Applying neutralizer too soon during the perming process will actually cause the perm to fall. So applying them both at the same time would defeat the purpose of doing a perm.

What happens to the hair during the perming process?
Once this happens the hair is in a state to change to the new shape of the perming rod. During the moulding phase of the perming process the disulphide bonds are broken.
