When neutralizer is applied to hair, it breaks down the hair's cysteine and sulphur bonds. This allows curls to form and stay for a while.
It builds back the disulphide bonds
sodium bicarbonate
The effect of shampoos on the tensile strength of hair are hard to determine. Depending on color of hair, brand of shampoo, and previous damage to hair, the results will differ.

Sodium thiosulphate solution (5-25 %)
No. It affects the 3-d structure of proteins AND nucleic acids.
effect water temperature has on hair structure
Neutralizer is used when putting a perm in hair. If you leave the neutralizer is the hair for 40 minutes it can do some serious damage t the root and ends of your hair and can cause it to break off.
Neutralizer are applied after a relaxer or perm. A relaxer straightens and a perm curls. Neutralizer locks the hair into it's straight shape and it also removes the chemicals from your hair to make it stop working.
LeTs look at perms, that hair is wrapped and the waving solution is put on, this breaks the disulfide bonds in the hair so they can reform into a curly state. The neutralizer is applied to keep the disulfide bonds in that state. I'd it is not appliend the hair will be limp and hold no curl. In a relaxer the neutralizer does the same thing. It keeps the reformed disulfide bonds in their new structure while also bringing the pH of the hair back down to normal.
No. The perm solution is a chemical and if you don't use a neutralizer to stop the chemical it will destroy your hair.

It stops the action of the waving solution and rebuilds the hair into it's new form
Perms are chemical treatments that create curls or waves in straight hair. They work by breaking hair bonds, setting it on rods, applying a solution, and then using a neutralizer to reform the bonds. This process alters the hair's structure, requiring proper care and maintenance.
