During permanent waving, four key chemical reactions occur:
- Reduction - The disulfide bonds in the hair's keratin structure are broken down using a reducing agent, typically ammonium thioglycolate.
- Neutralization - An oxidizing agent, such as hydrogen peroxide, is applied to reform the disulfide bonds in a new shape after the hair has been wrapped in curlers.
- Oxidation - This process helps to stabilize the newly formed disulfide bonds, ensuring the curls hold their shape.
- Conditioning - Finally, conditioning agents may be added to restore moisture and improve the overall texture of the hair after the chemical process.
What else can I help you with?
During the processing time in chemical waving the hair has a tendency to?
During the processing time in chemical waving, the hair has a tendency to soften and become more pliable. This allows the hair to be reshaped into a desired wave or curl pattern when wrapped on perm rods. It is important to monitor the processing time to avoid over-processing, which can lead to damage.
What is the main ingredient in a chemical waving neutralizer?
The main ingredient in a chemical waving neutralizer is typically sodium bisulfite or a similar sulfite compound. This ingredient works to neutralize the alkaline effects of the perm solution, allowing the hair to return to its natural pH and helping to set the new shape of the curls. Other ingredients may include stabilizers and conditioning agents to enhance hair health after the waving process.
NOT one of the waves of the electromagnetic spectrum?
Sound waves are not part of the electromagnetic spectrum. Sound waves are mechanical waves that require a medium to travel through, such as air, water, or solids, while electromagnetic waves can travel through a vacuum.
What is the common ingredient in a thio type relaxer and permant waving solution?
The common ingredient in a thio type relaxer and permanent waving solution is ammonium thioglycolate. This compound acts as a reducing agent, breaking disulfide bonds in the hair shaft to allow for restructuring.
What does waving lotion do in a perm?
Waving lotion softens and breaks down the hair's natural protein structure during the perming process. This allows the hair to be reshaped into a new curl pattern when wrapped around perm rods before the neutralization step.
Why is permanent waving beneficial to the client?
to look good
Why do permanent waves need to be neutralized?
Neutralizing the hair after a permanent wave helps to rebalance the pH level of the hair, which is disrupted during the perming process. This neutralization step also stops the chemical reaction of the waving lotion and helps to ensure that the hair remains in its desired shape after the perming process.

Where is permanent waving cream on the pH scale?
Permanent waving cream typically has a pH around 9-10, which is alkaline. This alkaline pH helps to break the disulfide bonds in hair to allow for restructuring and setting of the hair in a new shape.
Why must oxidation haircolors permanent waving solutions and chemical hair relaxers have an alkaline pH?
Alkaline pH helps to open the hair cuticle, allowing the chemical substances in these products to penetrate the hair shaft effectively. This process is necessary for permanent change in the hair structure during coloring, perming, or relaxing treatments. Alkaline pH also helps to break down and reconfigure the hair proteins to achieve the desired results.
What are permanent cold waving precaution?
i have pain below my eye brow.because of cold please tell me how to take care from this
Hair coloring products that contain metallic salts are not compatible with?
hair treatments involving peroxide or bleach, as they can react and cause damage to the hair. It is important to avoid mixing these types of products to prevent adverse reactions and potential hair damage.
