How it works:
1. The hair is wrapped around rods: The hair is sectioned and carefully wrapped around perm rods of various sizes and shapes, which determine the size and style of the curl or wave.
2. Perming solution is applied: A chemical solution, often containing ammonium thioglycolate, is applied to the hair. This solution breaks down the disulfide bonds in the hair's protein structure (keratin). These bonds are what give hair its shape.
3. Hair reforms around the rods: While the disulfide bonds are broken, the hair becomes pliable and conforms to the shape of the perm rods.
4. Neutralizer is applied: After a specific processing time, the perming solution is rinsed out thoroughly. A neutralizer (usually hydrogen peroxide) is then applied. The neutralizer re-forms the disulfide bonds, but this time they're reformed in the new, curled or waved shape created by the rods.
5. Rods are removed and hair is rinsed: Once the neutralizer has processed, the rods are carefully removed, and the hair is rinsed again.
6. Final styling: The hair is styled, typically with products designed for permed hair to maintain the curls/waves and prevent frizz.
Types of Perms:
Perms come in different styles and are often categorized by the type of rods used or the desired result:
* Spiral Perm: Hair is wrapped around long, thin rods to create tight, spiral curls.
* Body Wave: Uses larger rods to create loose, natural-looking waves, adding volume and texture.
* Root Perm: Applied only to the roots of the hair to add volume and lift. This is useful for people whose perms have grown out or for adding volume to fine, limp hair.
* Digital Perm (or "Hot Perm"): Uses heat in addition to chemical solutions to create looser, more natural-looking curls or waves. This is often popular for creating Korean-style waves.
* Acid Perm: Uses a lower pH solution, which can be gentler on the hair but may not create as strong or long-lasting a curl.
* Alkaline Perm: Uses a higher pH solution for a stronger, more defined curl, but can be more damaging to the hair.
* Multi-Textured Perm: Uses different sized rods to create a more varied and natural curl pattern.
Things to Consider:
* Hair Condition: Perms are chemical processes that can damage the hair. If your hair is already damaged, dry, or color-treated, a perm may not be a good idea or require extra care.
* Hair Type: Different hair types react differently to perms. Fine hair may be more prone to damage, while coarse hair may require a stronger solution.
* Maintenance: Permed hair requires special care, including moisturizing shampoos and conditioners, leave-in treatments, and styling products designed for curly hair.
* Professional Application: It's crucial to have a perm done by a qualified and experienced stylist. Improper application can lead to hair damage, breakage, or an undesirable result.
* Regrowth: As your hair grows, the permed portion will move further away from your scalp. You may need to get a retouch perm on the new growth every few months.
* Cost: Perms can be expensive, depending on the length and thickness of your hair, the type of perm, and the salon you choose.
In summary, a perm is a chemical treatment that permanently alters the hair's structure to create curls or waves. It's essential to consider your hair's condition, type, and desired outcome before getting a perm and to have it done by a professional.
