Perms have long been a popular choice for those seeking voluminous curls, waves, or texture in their hair. However, with the glamorous results come questions and concerns about the potential damage that comes with the perming process. In this article, we will examine the effects of a perm on hair, the factors that influence hair health during and after the process, and how to care for permed hair to minimize damage. Whether you’re considering getting a perm or you’re simply curious about the risks involved, this article provides an in-depth look at how damaging a perm really is.
What is a Perm?
A perm is a chemical treatment that changes the structure of the hair, making it curly or wavy. The process involves using a combination of chemicals to break the disulfide bonds in the hair, which are responsible for its natural shape. These bonds are then reformed around curlers, rods, or another tool to create curls or waves. After the hair is set in the new shape, a neutralizer is applied to restore the disulfide bonds in their new form.
Though the term “permanent” is used, the results typically last from 2 to 6 months, depending on hair growth, hair care, and the specific perm technique used.
The Perming Process
Preparation: The hair is washed to remove any buildup, making it easier for the perming chemicals to penetrate.
Application of Perm Solution: A perm solution, typically containing ammonium thioglycolate or similar chemicals, is applied to break the hair’s natural bonds.
Wrapping: The hair is wrapped around perm rods or curlers to set the new shape.
Processing Time: The perm solution needs time to work on the hair, typically ranging from 15 to 30 minutes.
Rinsing and Neutralizing: After the perm solution has processed, the hair is rinsed and neutralizer is applied to set the new curl pattern.
How Damaging is a Perm?
Like any chemical treatment, perms can cause damage to the hair if not done properly or if proper aftercare is neglected. The damage primarily occurs due to the chemicals used in the perming process and their effects on the hair’s structure.
1. Chemical Damage
The most significant risk of damage comes from the chemicals used to break and reform the hair’s bonds. The primary chemical agents used in perms, ammonium thioglycolate or similar compounds, work by breaking down the hair’s protein structure. While this is necessary for creating curls, the process also weakens the hair, potentially leading to dryness, brittleness, and breakage.
Cuticle Damage: The hair’s cuticle (the outer layer) is often lifted during the perming process, leaving the hair more porous and vulnerable to environmental damage.
Structural Weakening: The chemical process changes the disulfide bonds that hold the hair’s natural structure together. The weakening of these bonds makes hair more prone to breakage and split ends.
2. Dryness and Brittleness
After a perm, the hair can feel dry or brittle due to the chemical alterations. Since the cuticle layer is lifted, it can no longer retain moisture as efficiently. Additionally, the neutralizing process can further strip the hair of its natural oils, leaving it feeling rough and fragile.
3. Frizz and Unruliness
Permed hair can become frizzy or difficult to manage, especially if the hair is fine or naturally dry. The reformed curl structure can cause the hair to puff up or frizz in humid conditions, particularly if the perm was not applied correctly or if the hair is overprocessed.
4. Hair Breakage
When hair is weakened by the chemical treatment, it becomes more prone to breakage. This is especially true if the hair is subjected to heat styling, rough handling, or frequent washing without adequate moisture. Additionally, perming can weaken previously healthy, strong hair, causing it to snap off at the shaft.
5. Overprocessing
If the perm solution is left on for too long or applied too frequently, it can overprocess the hair, causing irreversible damage. Overprocessed hair can become limp, frizzy, and unmanageable. It may also become so weak that it’s prone to snapping, particularly when brushed or combed.
Factors That Influence How Damaging a Perm Can Be
The damage a perm causes can vary depending on several factors, including your hair type, the condition of your hair prior to the perm, and how the perm is applied.
1. Hair Type and Texture
Fine or Thin Hair: Fine or thin hair is more susceptible to damage from chemical treatments, including perms. Because fine hair has less natural strength, the chemical process can be more damaging, leading to thinning or breakage.
Thick or Coarse Hair: Thicker hair tends to be more resistant to damage from perms, but it still requires proper care to maintain health after the treatment.
Curly Hair: Curly hair may be more resilient during a perming process but can also be prone to frizz and dryness afterward.
Damaged Hair: If your hair is already damaged from previous treatments, the perm may cause additional stress and damage, especially if it’s already dry, brittle, or chemically treated.
2. The Strength of the Perm Solution
The strength of the perm solution used can also determine how damaging the process is. Stronger solutions are more likely to cause damage, especially if left on for too long. Conversely, milder solutions may result in less damage but could require more frequent touch-ups or may not create as dramatic of a curl.
3. Professional vs. At-Home Perms
Professional perming is typically safer and less damaging because stylists are trained to handle the chemicals correctly, assess the condition of your hair, and apply the right strength of perm solution. At-home perms, however, can be tricky and more damaging if applied incorrectly. Mistakes like leaving the solution on too long, overprocessing, or using the wrong strength of solution can cause significant harm to the hair.
4. Aftercare
Proper aftercare can help mitigate the damage caused by a perm. Hydrating treatments, such as deep conditioning masks and leave-in conditioners, can restore moisture and repair damaged hair. Regular trims to remove split ends and reduce frizz can also help maintain the health of permed hair.
How to Minimize Damage from a Perm
While perms can cause damage, there are steps you can take to minimize the effects and keep your hair looking healthy.
1. Deep Conditioning Treatments
After getting a perm, it’s crucial to restore moisture to your hair. Use deep conditioning masks or oils to hydrate the hair shaft and keep it from becoming dry and brittle. Look for products that contain ingredients like argan oil, shea butter, and keratin to nourish and repair the hair.
2. Avoid Heat Styling
Heat styling tools like flat irons and curling wands can exacerbate the damage caused by a perm. Try to avoid excessive use of these tools, especially within the first few weeks after a perm, as your hair is more vulnerable to heat damage. If you must use them, always apply a heat protectant beforehand.
3. Gentle Hair Care
Be gentle with your hair after a perm. Use a wide-tooth comb to detangle wet hair, and avoid pulling or tugging, which can cause breakage. When drying your hair, pat it gently with a towel instead of rubbing it, which can damage the curls and cause frizz.
4. Regular Trims
Trim your hair every 6-8 weeks to remove split ends and keep your curls looking fresh. This also helps prevent any potential breakage that could occur if damaged ends are left unattended.
5. Hydrating Products
Invest in sulfate-free shampoos and conditioners designed for permed or chemically treated hair. These products are gentler on the hair and help maintain moisture, ensuring that your curls stay soft and healthy.
6. Choose a Low-Strength Perm Solution
If you’re concerned about the damage a perm may cause, opt for a low-strength perm solution. These are less harsh on the hair, reducing the risk of excessive dryness or breakage, though they may require more frequent touch-ups.
Conclusion
While a perm can create beautiful, long-lasting curls or waves, it does come with the potential for damage. The chemicals used in the perming process can weaken and dry out the hair, leading to frizziness, brittleness, and even breakage. However, with proper aftercare and attention to your hair’s condition, the damage can be minimized, allowing you to enjoy the benefits of permed hair without compromising its health. If you have delicate or damaged hair, it’s essential to weigh the pros and cons before opting for a perm and consider professional help for the best results.
Ultimately, the key to maintaining healthy permed hair is regular maintenance, hydration, and gentle handling. With the right approach, you can enjoy your curls while keeping your hair strong and beautiful for months to come.
