The Silver Star perm guide
How Do Perms Work?
The science, the salon process and the real results.
A perm changes the hair you already have. Learn what happens inside a strand, why rods matter and how the service is planned around your hair. Then see real work from Silver Star Salon.

Change some bonds.
Hold a new shape.
Think of a strand as a tiny bundle of connected protein structures. A perm changes some of the connections, not just the way the outside looks.
That is different from a temporary roller set. A permanent wave changes the treated fiber itself. The visible finish still depends on the haircut and styling.[1]
Four ideas, shown clearly
What happens inside the hair?
Each drawing explains one part of the process. Open any diagram for a larger view. These are simplified models, not photographs of molecules.
Hair has an outer cover and an inner structure.
The cuticle is the outside layer. The cortex lies beneath it and contains much of the hair's keratin structure. Keratin is a protein.[1]
Some parts of that structure are joined by strong sulfur connections called disulfide bonds. These are among the connections affected during permanent waving.[2]
In everyday wordsThe outside is the cover. The important shape change happens within the hair.
The solution changes some sulfur connections.
The chemical step is called reduction. A reducing ingredient changes some disulfide bonds into groups called thiols, shown as SH in the drawing.[2]
The aim is controlled reshaping, not maximum bond breaking. Repeated chemical processing can leave changes that neutralization does not completely undo.[2]
In everyday wordsSome little bridges change so the hair can move into a different shape.
See the simplified chemistry
RSSR + 2H+ + 2e− → 2RSH
R stands for the attached part of the protein. SS is the sulfur connection. SH is a thiol group. The equation is a schematic reduction half reaction, not a formula for mixing salon chemicals.
The rod gives the hair a form to follow.
A smaller cylinder makes the wrapped hair bend more sharply. A larger cylinder makes a broader bend. That is geometry, but it is not a guarantee of the finished curl size.
Length, section size, placement and the chosen wrap method also matter. A formula can even offer different wrapping options for different texture goals.[4]
In everyday wordsThe rod helps choose the bend. The hair and the full service determine the result.
This is a science sequence, not a strict appointment sequence. In a common water wrap method, the hair is wrapped before the waving lotion is applied. Other systems have different directions.
Neutralization helps stabilize the altered shape.
After the prescribed rinsing stage, an oxidizing neutralizer helps reestablish disulfide connections. Hydrogen peroxide is one ingredient used in commercial neutralizers.[3][4]
Neutralizing is more than adding conditioner. Rinsing also matters: laboratory work has found that chemical changes can occur during that stage too.[3]
In everyday wordsConnections form again while the hair is in its new arrangement. That helps the shape last.
See a peroxide example
2RSH + H2O2 → RSSR + 2H2O
This simplified oxidation equation shows a possible peroxide pathway. Real perm chemistry is more complex. Not every neutralizer uses the same chemistry, and processed hair is not identical to untouched hair.
From the diagram to the chair
How a perm appointment comes together
Silver Star's consultation starts with the result you want, your length, density, condition and chemical history. The service approach and placement follow from that discussion.[8]
The outline below describes a conventional salon perm. Exact preparation, testing, timing and rod removal follow the chosen product's directions.
Talk through the goal
Bring photos of movement you like and texture you do not want. Tell May or Tammy about lightening, color, previous perms and straightening that remains on your hair.
Prepare and choose the wrap
The stylist selects a suitable system, prepares the hair and sections it for the intended shape. A common method wraps damp hair before applying waving lotion.
Apply and monitor the formula
The formula's directions govern application and checking. Some products require test curls during processing; others specifically say not to take them. One routine does not fit every bottle.[4][5]
Rinse and remove excess water
Rinsing removes waving lotion. Blotting and any other required steps prepare the hair for neutralization. These stages should not be treated as an afterthought.[3]
Complete neutralization
The selected system specifies how neutralizer is applied and when rods are removed. This is a chemical stage, not simply a finishing treatment.
Finish the haircut and explain care
The completed shape needs to work beyond the appointment. Silver Star discusses styling, maintenance and home care as part of the service.[8]
May Wong and Tammy Phang
At Silver Star, the plan begins with your hair.
May and Tammy lead the family owned salon on Florin Road. Silver Star has served Sacramento for more than 30 years.[9]
For perms, the salon describes a consultation around hair condition, chemical history, desired curl, movement and maintenance. Partial, top and full head services let the plan match the areas where texture is wanted.[8]
Tell us what you want the texture to do.
"I want movement on top, but I like the sides close."
"I want softer waves, not small ringlets."
"My hair feels flat near the front. What shape is realistic?"
These are useful starting points for a conversation with May or Tammy. They communicate a goal without prescribing a rod size or a chemical strength.
What the bottles do
Waving lotion, neutralizer and haircare are different.
A product name is not a complete technique. The ingredients and directions matter. These named professional systems illustrate the difference between the chemical steps.
| Waving lotion | Quantum Firm Options lists ammonium thioglycolate. Texture EFX Color Treated Perm lists cysteamine HCl. These are different reducing ingredients used in different professional formulas.[4][5] |
|---|---|
| Neutralizer | Both examples list hydrogen peroxide in their neutralizers. That is separate from the waving lotion and has a different chemical role.[4][5] |
| Haircare at Silver Star | Silver Star lists Paul Mitchell, including Tea Tree, and OLAPLEX No.0 among its professional haircare products. OLAPLEX describes No.0 as a treatment used with its companion treatment, not as a perm neutralizer. Ask May or Tammy which care routine fits your finished texture.[9][10] |
Brand availability can change. The actual waving formula, compatible care products and service instructions should be confirmed for your appointment. A care treatment does not make unsuitable hair automatically ready for a perm.
A real Silver Star transformation
Long hair to a shorter shape with visible lift
These three photos show the same client before and after her salon visit. Limited fullness at the front was part of the styling challenge. The finished views show a shorter, rounded shape with soft movement.
What changed
The visible transformation includes the haircut, texture and finishing. It would be misleading to attribute the entire difference to the perm solution alone.
What the photos show
The after photos show a different distribution of shape and movement. They are salon images, not a controlled comparison with matched angles or lighting.
What they do not show
The photos do not establish a product, processing time or new hair growth. A fuller looking shape is not the same thing as more hair follicles.
More real salon work
Different haircuts. Different texture goals.
These supplied client photos show the variety of perm finishes created at Silver Star. Use them to describe the amount of movement, length and shape you like.
Some photos show a freshly styled or damp finish. The dry finish and home styling may look different. No product or rod size is inferred from these photographs.
Why the same plan does not fit everyone
How hair type and condition change the conversation
A visual label such as straight, gray or thick is not a processing clock. Research on perm chemistry describes different reaction rates across hair samples. There is no reliable universal minutes chart based only on appearance.[6]
Straight or already wavy hair
The starting pattern helps define the design goal. Ask whether you want a new curl pattern, more movement in selected areas or a different silhouette. Existing wave alone does not establish chemical suitability.
Fine hair or lower density
Fine describes individual strand thickness. Density describes how much hair is present. Explain whether your concern is delicate strands, limited fullness or both. Those are different planning questions.
Coarse strands or dense hair
Do not turn "thick hair" into an automatic request for stronger lotion. Strand thickness, total amount of hair, past services and the chosen formula need separate consideration.
Highlighted or bleached hair
Oxidative bleaching can change pore structure and the condition of the fiber. The lighter sections and darker sections may have different histories. Tell the stylist where previous lightening remains.[7]
Gray hair
Gray describes pigment, not a complete chemical history. The transformation above shows one client's result. It is not evidence that every gray head needs the same product or timing.
Long hair or an old perm
Ask how much treated length remains and where the new service would overlap. More length also changes the shape you see. A repeat service should not be planned as though all of the hair were new.
Quality comes from the whole service
What helps avoid an unsuitable result?
Silver Star's consultation is where your goal and hair history are brought together. The practical checks below explain why careful planning matters. They are principles to discuss with your stylist, not a guarantee of a damage free service.
A realistic starting point
Speak up about breakage, previous reactions and every chemical service that remains on the hair. A desired style does not automatically make the hair suitable for more processing.
Product specific instructions
A preliminary suitability assessment is not the same as repeatedly unwrapping a curl during processing. The monitoring method needs to match the selected system.[5]
Controlled wrapping
Secure does not mean pulled as tightly as possible. Controlled sectioning and appropriate tension matter. Manufacturer education specifically cautions against excessive wrap tension.[4]
Complete finishing and care
Rinsing and neutralization are part of the chemistry, not optional extras. Then the haircut and home routine need to make sense for the new texture.
Questions before you call
Perm questions, answered clearly
Does a perm change new hair as it grows?
No. The chemical service acts on the existing hair it treats. New growth is not automatically permed. The haircut and visible pattern can change as hair grows and is trimmed.
Does neutralizer repair every bond?
No. Neutralization helps reestablish connections after reshaping, but that does not mean every original connection returns or the fiber becomes untouched hair again. Laboratory studies document lasting changes after chemical processing.[1][2]
How long should the solution stay on?
There is no single time for every head and formula. Follow the selected professional system, its suitability guidance and its checking method. A timer chosen from a hair color or ethnicity label would not account for the full situation.[6]
Will a perm make thinning hair grow?
A perm changes the shape of existing hair. The shorter gray transformation on this page shows a styling result, not a hair growth treatment. Texture and haircut shape can change the appearance without changing the number of hairs.
Can highlighted hair be permed?
It requires an individual assessment. The extent of lightening, overlap, current condition and product restrictions matter. Do not assume a smooth looking surface means the internal fiber has no previous damage.[7]
Will my result look exactly like one of these photos?
The photos are useful references, not promises. Describe the details you like. Your length, haircut, starting texture, condition and styling routine still need their own plan.
What should I ask May or Tammy?
Ask what result your current hair can support, where the texture should be placed, what formula will be used, what its instructions require and how you should style it afterward. Bring your chemical history and a few reference photos.
