Digital Perm vs Cold Perm: What Is the Difference and Which Should You Choose?
Key Takeaways
- Both digital perms and cold perms create long-lasting curls, but they use different techniques.
- Digital perms typically produce softer, looser waves, while cold perms create tighter, more defined curls.
- Hair length, texture, maintenance preferences, and desired style all play a role in choosing the right perm.
- The longevity and styling requirements of each treatment differ.
- Proper aftercare helps maintain curl definition and overall hair health.
Introduction
If you are considering adding curls or waves to your hair, you may come across two popular options: digital perm and cold perm. While both treatments are designed to create long-lasting texture, they deliver very different results.
In this guide, we’ll explore the key differences between these two types of perms, discuss how each works, who it suits best, and what to expect after your appointment.
What Is a Digital Perm?
A digital perm is a modern perming technique that combines chemical solutions with controlled heat to reshape the hair’s internal structure.
During the digital perm process, the stylist wraps your hair around heated rods connected to a specialised machine that maintains a consistent temperature throughout the treatment. The heat helps create softer, more natural-looking waves that often resemble hair styled with a curling iron. Once the hair is dry, the curls become more visible and tend to have a relaxed, flowing appearance.
What Is a Cold Perm?
On the other hand, a cold perm is a traditional perming technique that creates curls without using heat.
Stylists apply a chemical solution to break and reform the hair’s natural bonds while the hair is wrapped around perm rods. Since the curls are formed directly around the rod shape without the assistance of heat, the resulting curl pattern is often tighter, springier, and more noticeable from the roots.
The final look depends largely on the rod size used, with smaller rods creating more defined curls and larger rods producing looser waves. The way you style and dry your hair can also affect the tightness of the curls.
Should You Choose a Digital Perm or Cold Perm?
Before you decide between the two types of perms, here are some factors to consider.
1. The Results You're Looking For
First, think about the look you want to achieve.
If you’re after soft, flowing waves with a polished, salon-styled finish, a digital perm is often the preferred choice. The curls tend to be looser and more natural-looking, often starting at the eyes and extending to the cheekbones. Digital perms also create curls that become more defined when blow-dried, giving you greater control over the final style.
For those who want their curls to begin closer to the roots, a cold perm might be more suitable. Because the curl pattern is generally tighter, cold perms can create a fuller, more textured appearance, particularly on shorter hairstyles or finer hair. However, the curls can be softened with some blow-drying, giving you the flexibility to wear them either textured and bouncy or more relaxed and natural-looking.
2. How Long You Want the Curls to Last
If longevity is a priority, a digital perm often has an advantage.
Digital perms typically last around four to six months and are known for maintaining their shape well over time. As the hair grows, the waves generally soften gradually, creating a more natural transition between the permed and new growth.
Cold perms generally last around three to five months. While the curls can initially appear more defined, they may loosen more noticeably over time. The contrast between new growth and the permed sections can also become more apparent as the hair grows out.
That said, individual results will vary depending on factors such as hair texture, hair care habits, and Singapore’s humid climate.
3. Your Hair Length
The length of your hair can also affect how each perm looks.
If you have medium to long hair, digital perms may be more suitable for you. The additional length allows the waves to develop fully and truly showcase their movement. Layered haircuts can further enhance this soft, cascading effect.
Cold perms can work well on both short and long hair, but they are particularly popular for shorter hairstyles. Since the curls can start closer to the roots, they are often chosen by those looking to create more volume throughout the hair. However, those with highly frizzy or heavily rebonded hair may need a professional assessment to determine whether a cold perm is the most suitable option.
4. The Ease of Maintenance
Your styling routine is another important factor to consider.
A digital perm is often favoured by those who prefer a more effortless daily routine. The waves typically look their best after blow-drying, and many people find that a little styling product is enough to maintain the shape. For those who enjoy a polished, salon-finished look without spending too much time styling, this can be a significant advantage.
Cold perms can be lower maintenance in a different way because the curls remain visible even when the hair is air-dried. It’s best to simply apply some mousse or styling product and leave it to dry on its own for a bouncy effect.
Ultimately, the best perm for you depends on your hair condition, texture, styling habits, and the look you want to achieve.

Tips to Maintain Your Curls
Regardless of whether you choose a digital perm or a cold perm, proper aftercare can help keep your curls looking their best for longer while maintaining your hair’s overall health.
1. Use a Gentle Shampoo in the First Few Washes
You do not necessarily need to avoid washing your hair immediately after a perm, as the curl structure has already been set during the neutralising step of the treatment. However, the products you use afterwards still matter.
In the first few washes, it is generally better to avoid deep-cleansing or scalp shampoos, as these can feel too harsh on freshly permed hair and may leave it drier or rougher than necessary. A gentler shampoo formulated for damaged, dry, or chemically treated hair is usually a better option while your hair settles into its new texture.
2. Use Products Designed for Curly or Permed Hair
Permed hair tends to require more moisture than untreated hair. Using conditioners, creams, and styling products formulated for curly or chemically treated hair can help keep your curls hydrated, reduce frizz, and maintain a softer, more defined appearance.
3. Reduce Excessive Heat Styling
While occasional heat styling is unlikely to cause significant issues, frequent use of curling irons, straighteners, or high-heat blow-dryers may gradually weaken the curl pattern over time. When using heat tools, applying a heat protectant can help minimise unnecessary stress on the hair.
4. Schedule Regular Hair Treatments and Trims
Permed hair usually looks best when both the condition and shape of the hairstyle are maintained over time. Conditioning or repair treatments can help replenish moisture, improve manageability, and keep hair feeling soft, especially if you also colour or heat-style it regularly.
We recommend coming back for a trim around two to three months after your perm. Refreshing the layers and overall shape can help the curls sit better, prevent the ends from looking heavy or uneven, and make the perm last more beautifully as it grows out.
Conclusion
Choosing between a digital perm and a cold perm ultimately comes down to the style you want, your hair characteristics, and how much time you’re willing to spend on daily maintenance. While digital perms are often favoured for their soft, natural-looking waves, cold perms can be a great option for those who prefer stronger curl definition and added texture.
