Alkaline Perms Carry A Ph Of

Alkaline perms utilize a specific pH level to effectively reshape hair, making it crucial to understand this aspect for both stylists and clients. The pH level is not just a number; it's a key factor that determines how the perm solution interacts with the hair structure, influencing the final result and the health of the hair.

Understanding pH in Perming

pH, or potential of hydrogen, is a measure of the acidity or alkalinity of a solution. The pH scale ranges from 0 to 14, with 7 being neutral. Values below 7 indicate acidity, while values above 7 indicate alkalinity. In the context of hair perming, the pH level of the perming solution is critical because it affects the hair's cuticle and cortex.

The Role of pH in Hair Structure

Hair's natural pH is slightly acidic, around 4.5 to 5.5. This acidity helps to keep the hair cuticle closed and the hair shaft strong. When an alkaline solution is applied, it causes the hair shaft to swell, opening the cuticle layers and allowing the perming chemicals to penetrate the cortex, where the disulfide bonds responsible for hair's shape are located.

Alkaline Perms: The pH Range

Alkaline perms typically have a pH range of 9.0 to 9.6. This high pH is necessary to effectively swell the hair shaft and allow the reducing agent, usually ammonium thioglycolate, to break the disulfide bonds. The higher the pH, the faster and more aggressively the solution works, which can be beneficial for certain hair types but also carries a greater risk of damage.

Why Alkaline Perms Need a High pH

1. Cuticle Swelling: Alkaline solutions are effective at opening the hair cuticle. This is essential for the perming solution to reach the cortex.
2. Disulfide Bond Disruption: The high pH facilitates the action of the reducing agent, which breaks the disulfide bonds that give hair its shape.
3. Efficient Perming Process: The alkalinity ensures that the perming process occurs in a reasonable amount of time, making it practical for salon use.

The Science Behind Alkaline Perms

To truly understand alkaline perms, it's crucial to delve into the science of how they work at a molecular level. The primary chemical reaction involves breaking and reforming the disulfide bonds in the hair.

Disulfide Bonds: The Key to Hair's Shape

Disulfide bonds are chemical links between sulfur atoms within the protein chains of hair. These bonds give hair its strength, elasticity, and shape. Natural hair shape (straight, wavy, curly) is determined by the arrangement and number of these disulfide bonds.

The Chemical Process

1. Alkalization: The alkaline solution raises the pH of the hair, causing the cuticle to swell and open. This allows the perming solution to penetrate the hair shaft.
2. Reduction: The reducing agent (ammonium thioglycolate in most alkaline perms) breaks the disulfide bonds. This process softens the hair and allows it to be reshaped around a perm rod.
3. Neutralization: After the hair has been reshaped, a neutralizing solution (usually hydrogen peroxide) is applied. This solution re-oxidizes the disulfide bonds, reforming them in their new position, thereby setting the new curl pattern. The neutralizer also lowers the pH of the hair, closing the cuticle.

The Role of Ammonium Thioglycolate

Ammonium thioglycolate (ATG) is the active ingredient in most alkaline perms. It's a reducing agent that works best in an alkaline environment. The alkaline pH of the perming solution helps ATG to effectively break the disulfide bonds.

Chemical Equation Simplified

Hair-S-S-Hair + 2 R-SH  →  2 Hair-SH + R-S-S-R

Where:

• Hair-S-S-Hair represents the disulfide bond in hair.
• R-SH represents the reducing agent (ammonium thioglycolate).
• Hair-SH represents the broken disulfide bonds.
• R-S-S-R represents the oxidized form of the reducing agent.

Types of Perms

Perms are broadly classified based on their pH level and the primary chemicals used. Understanding these differences helps in selecting the right perm for different hair types and desired outcomes.

Alkaline Perms vs. Acid Perms

The main difference lies in the pH level:

• Alkaline Perms: pH 9.0-9.6. They use ammonium thioglycolate and process at room temperature.
• Acid Perms: pH 4.5-7.0. They use glyceryl monothioglycolate (GMTG) and require heat to process effectively.

Key Differences in Detail:

Feature	Alkaline Perms	Acid Perms
pH Level	9.0-9.6	4.5-7.0
Active Ingredient	Ammonium Thioglycolate (ATG)	Glyceryl Monothioglycolate (GMTG)
Processing	Room Temperature	Requires Heat
Hair Type	Suitable for resistant hair	Suitable for delicate hair
Damage Potential	Higher	Lower
Curl Tightness	Tighter, more defined curls	Softer, more natural curls
Odor	Stronger ammonia-like smell	Less noticeable smell
Longevity	Can last longer, but more damage	May fade faster, but less damage

Other Types of Perms

1. Exothermic Perms: These perms generate their own heat. They typically have a pH between acid and alkaline and are designed for faster processing.

2. Thio-Free Perms: These perms use chemicals other than ammonium thioglycolate to reduce the disulfide bonds. They are often marketed as gentler alternatives, but their effectiveness can vary.

3. Digital Perms (or Hot Perms): Popular in Asia, these involve a combination of chemical treatment and heat styling. The hair is permed using chemicals and then styled with heated digital rods to create soft, natural-looking waves.

Choosing the Right Perm

Selecting the right perm depends on several factors, including hair type, condition, and desired outcome.

Assessing Hair Type and Condition

1. Hair Porosity: High porosity hair (damaged, dry) absorbs chemicals quickly and is more prone to damage from alkaline perms. Low porosity hair (healthy, resistant) is harder to perm and may require a stronger alkaline solution.
2. Hair Texture: Fine hair is more easily damaged than coarse hair. Alkaline perms can be too harsh for fine hair, leading to breakage and frizz.
3. Previous Chemical Treatments: Hair that has been previously colored, bleached, or permed is more susceptible to damage. A milder perm solution is usually recommended.

Desired Outcome

1. Curl Pattern: Alkaline perms generally create tighter, more defined curls. Acid perms produce softer, more natural-looking waves.
2. Longevity: Alkaline perms tend to last longer, but they can also cause more damage. Acid perms may fade faster but are gentler on the hair.

Consultation with a Professional

It's crucial to consult with a professional hairstylist before getting a perm. A stylist can assess your hair's condition, discuss your desired outcome, and recommend the most suitable type of perm. They can also perform a strand test to determine how your hair will react to the perming solution.

The Perming Process: Step-by-Step

Understanding the perming process can help clients know what to expect and ensure that the procedure is performed correctly.

Preparation

1. Consultation: The stylist assesses the hair and discusses the desired outcome.
2. Strand Test: A small section of hair is permed to test the solution and processing time.
3. Haircut: The hair is cut and shaped before perming.
4. Sectioning: The hair is divided into sections for even application of the perming solution.

Application

1. Rod Placement: The hair is wrapped around perm rods of the desired size.
2. Perming Solution: The alkaline perming solution is applied to each rod.
3. Processing: The solution is left on the hair for a specified time, usually 10-20 minutes, depending on the hair type and strength of the solution. The hair is checked periodically to assess the curl development.
4. Rinsing: The perming solution is thoroughly rinsed from the hair.

Neutralization

1. Neutralizer Application: The neutralizing solution is applied to the hair while it is still wrapped on the rods.
2. Setting Time: The neutralizer is left on the hair for about 5-10 minutes to re-oxidize the disulfide bonds.
3. Rod Removal: The rods are carefully removed, and the neutralizer is applied again to ensure complete neutralization.
4. Final Rinse: The hair is thoroughly rinsed with water.

Finishing

1. Conditioning: A deep conditioner is applied to restore moisture to the hair.
2. Styling: The hair is styled as desired, usually with curl-enhancing products.

Risks and Precautions

While perms can transform hair, they also carry risks, especially with alkaline perms due to their high pH.

Potential Damage

1. Hair Breakage: Over-processing can weaken the hair, leading to breakage and split ends.
2. Dryness and Frizz: The alkaline solution can strip the hair of its natural oils, causing dryness and frizz.
3. Scalp Irritation: The chemicals can irritate the scalp, leading to redness, itching, and even chemical burns.
4. Color Fading: Perming can cause hair color to fade more quickly.

Precautions

1. Professional Application: Always have a perm done by a licensed and experienced stylist.
2. Strand Test: Insist on a strand test to assess how your hair will react to the solution.
