1. Hair Perming Solution Ingredients: The main purpose of the perming solution (also called a waving lotion) is to break the disulfide bonds in the hair, allowing it to be reshaped. The key ingredients in the perm solution typically include:
Ammonium Thioglycolate (cold perm): This is the most common reducing agent used in cold perming (alkaline perming). It breaks the disulfide bonds in the hair.
Glyceryl Monothioglycolate (acid perm): This is a gentler option compared to ammonium thioglycolate, often used in acid perms or perms for more fragile hair. It works at a lower pH.
2. Neutralizer Ingredients: The neutralizer is used to reform the disulfide bonds in the new shape of the hair. Key ingredients typically include:
Hydrogen Peroxide or Sodium Bromate: These are common oxidizing agents that help to reform the broken disulfide bonds.
Sodium Perborate: Another oxidizing agent sometimes used in neutralizers.
3. What Impacts Neutralizer Quality?
Oxidizing Agent Strength: The concentration of hydrogen peroxide or sodium bromate will affect how effectively and quickly the disulfide bonds are reformed.
pH Balance: The pH of the neutralizer should be balanced to avoid over-processing and damaging the hair.
Conditioning Agents: High-quality neutralizers often include conditioning agents to minimize damage and leave hair feeling smoother.
4. Which Bond is Broken During Perming? The main bond broken during perming is the disulfide bond in the keratin of the hair. Disulfide bonds are responsible for the hair's structure and shape.
5. What Ingredient Breaks Hydrogen Bonds? Water and heat are primarily responsible for breaking hydrogen bonds in the hair. These bonds are weaker than disulfide bonds and are temporarily disrupted when the hair is wet or heated. However, hydrogen bonds are not the primary focus in perming, as they naturally reform when the hair dries or cools.
6. Difference Between Cold Perm and Hot Perm Ingredients:
Cold Perm (Alkaline Perm):
Main Ingredient: Ammonium Thioglycolate
pH: 8.0 to 9.5 (alkaline)
Processing: Does not require heat; relies on the strength of the chemical solution.
Hot Perm (Digital/Heat Perm):
Main Ingredient: Ammonium Thioglycolate (same as cold perm) or Cysteamine.
pH: Often around 6.5 to 7.5 (slightly acidic to neutral)
Processing: Requires heat to assist in breaking the disulfide bonds and reforming the curl pattern.
Can Cold and Hot Perm Solutions be Used Interchangeably? No, they cannot be used interchangeably. Cold perms work without heat, and their chemical composition is more alkaline to break the bonds. Hot perms require heat to activate and reshape the hair structure.

Cold Perm and Hot Perm Neutralizer Differences:
Oxidizing Agent:
Cold Perm Neutralizer: The most common oxidizing agent is hydrogen peroxide (H₂O₂), usually in concentrations around 2-5%. This neutralizer helps to reform the disulfide bonds broken by the cold perm solution.
Hot Perm Neutralizer: Typically contains hydrogen peroxide as well, but due to the combination with heat during the perming process, the formulation may differ slightly in strength or additives to suit the heat-activated environment.
Formulation:
Cold Perm: The neutralizer in cold perms is designed for hair that has been processed at room temperature. It focuses more on oxidizing and reforming the disulfide bonds without the need for additional heat.
Hot Perm: Since hot perms involve the use of heat during the perming process, the neutralizer may include extra conditioning agents to help restore moisture and prevent excessive damage from the combination of heat and chemicals.
pH Balance:
Cold Perm Neutralizer: The pH is usually in the range of 3-5, slightly acidic to help restore the pH balance after the alkaline cold perm solution.
Hot Perm Neutralizer: The pH is also slightly acidic, but the neutralizer may be adjusted slightly to accommodate the effects of the heat during the perm process, often designed to counteract the higher damage risk from heat.
Can Cold Perm Neutralizer Be Used for a Hot Perm?
Technically, both cold and hot perm neutralizers use similar oxidizing agents (e.g., hydrogen peroxide), so in some cases, they can be interchangeable if absolutely necessary. However, it's not recommended to use cold perm neutralizer for a hot perm for the following reasons:
Heat Interaction: Hot perms use heat to reshape the hair, and the neutralizer is formulated to work with the effects of heat on the hair structure. Cold perm neutralizers are designed for hair processed at room temperature and may not provide sufficient protection or conditioning for heat-processed hair.
Conditioning Agents: Hot perm neutralizers often contain additional moisturizers or proteins to compensate for the extra dryness and damage caused by the heat. Cold perm neutralizers may lack these protective additives, leading to possible damage when used after a hot perm.
Perm Results: The results of a hot perm could be compromised by using a cold perm neutralizer, as the hair might not retain the curl pattern as effectively, or the bond reformation might be incomplete.
Recommendation:
While both neutralizers perform similar functions, it’s better to use the correct neutralizer designed for the type of perm you’re performing. Hot perm neutralizers are optimized for the heat-based process, while cold perm neutralizers are designed for chemical-only perms without heat. Using the right neutralizer ensures that the hair maintains its structure and remains healthy after the perm.
