A digital perm gives you soft waves or loose curls that look like you used a curling iron, with less day-to-day styling.
It is still a chemical service. It can dry out hair or cause breakage, especially on already damaged hair. A good stylist and a proper consultation matter.
Quick Answer: What is a digital perm?
A digital perm is a salon treatment that uses a perm solution plus heated rods to reshape hair into soft waves or loose curls that stay until the hair grows out.
Digital perm uses a heat-activated solution and digitally controlled hot rods. The solution can be more acidic or more alkaline, depending on your hair type and the salon’s system.
It is done using a machine. The stylist uses a digital display to control heat and timing. The process changes the structure of the hair so it holds waves or curls.
The Process:
The stylist applies a cream-type solution to soften the hair. Then they wrap sections around rods of different sizes, based on the curl pattern you want.
The rods connect to a machine that controls heat. While the machine regulates temperature, the rods still reach high temperatures (often above 80°C). This can help reduce the risk of extreme heat damage compared with older hot perm methods, but it still carries a risk of protein denaturation if timing is incorrect.
At the end, the stylist applies a neutralizer to stop the chemical action and help set the new shape.
Safety Notes
- Digital Perms require high heat (often 100°C+). This combination is usually fatal to bleached hair. We strongly recommend against digital perms on bleached or highlighted hair.
- Avoid doing color, bleach, relaxers, or another chemical service right before a perm.
- If you have used dyes containing metallic salts on any part of your hair present today, do NOT get a perm before doing a strand test. The ammonium thioglycolate in perm solutions can react violently with these metals, causing hair to smoke, burn, or melt. If you feel excessive burning while any perm solution is on your scalp, rinse right away and seek medical advice.
- If you have had reactions to hair dye or salon chemicals, tell your stylist and ask about patch testing. NHS guidance on reactions is here: Hair dye reactions. If you develop an itchy rash after exposure, learn the signs of contact dermatitis here: Contact dermatitis.
Things to Know Before Getting Digital Perm
Before you book, make sure a digital perm matches your hair goals and your hair condition.
- The digital perm gets its name from the machine it uses. Unlike a cold perm, a digital perm uses heated rods with a controlled temperature setting.
- Digital perms often create larger, softer waves. Many people find the finish looks shiny and smooth, but results depend on your hair and your stylist.
- If you spend a lot of time curling your hair, a digital perm can cut down daily styling time.
- Processing time depends on hair length, density, and texture. Many appointments run 2 to 3 hours. A cut or treatment can add more time.
- Book a consultation first if your hair is bleached, very dry, damaged, relaxed, or recently colored. Bleached hair is a high risk case. Many stylists will only proceed after a strand test, and some will not do it at all.
- Digital perms can feel higher maintenance than you expect. You may need better conditioning habits and gentler styling.
- If you swim often, protect your hair. Pool chemicals can be hard on hair. Dermatologists recommend wearing a swim cap and rinsing hair right after swimming.
- Digital perms can be costly. Prices vary based on salon location, stylist experience, your hair length and thickness, and whether a cut or treatment is included.
Beautiful Digital Perm Hairstyles
Here are permed styles to bring to your consultation. Some photos are style inspiration and may not show a true digital perm result.
1. Layered Multi-Textured Perm
Style inspiration: layered curls with mixed texture. Some celebrity photos show natural curls or styled curls, not a digital perm result.
To get a similar shape, ask for layers and a multi-textured perm plan that uses more than one rod size.
2. Luscious Body Perm
Big body waves can look like you used a curling wand, but they last much longer.
Consider a body wave perm for a bouncy result with less day-to-day curling.
3. Beach Wave Perm for Short Hair
A beach wave perm can add movement to fine hair. It also works well on short haircuts.
Short waves can look fuller than long straight hair, and they are often easier to style.
The curls can also balance a long or narrow face shape.
4. Beach Waves + Straight Bangs
This look pairs loose waves with a straighter fringe. It can look soft and intentional, not messy.
If you like curling your lengths every day, this is a good style to ask about.
5. Asian Hair Perm
Some salons tailor digital perm settings for thicker, straighter hair. They may use different solutions, rod sizes, and timing.
The goal is often a soft wave that feels natural and not stiff.
6. Feathered Perm
Wavy hair can respond well to a perm when done carefully. The solution choice matters, especially on fragile hair.
This feathered perm will refresh your hairstyle and give you softer shape through the lengths.
7. Messy Lob
The wavy perm hairstyle pairs well with a lob. Waves can make the cut look fuller and more modern.
Ask your stylist to keep the wave loose so it grows out gracefully.
Soft texture makes the shape feel lighter.
8. Side-Swept Hair
This easy style lets you sweep hair to one side. You can also try a side braid or a loose ponytail.
A side part can soften the face and show off the wave pattern.
9. Fluffy Waves
This soft wave is classic and easy to wear. You can adjust the curl size to match your density and length.
The style can show off texture and add volume. It can also be lower effort than daily heat styling.
How to Care for Digital Perms
Before you leave the salon, your stylist should explain aftercare. These are the common basics:
- Wait 2 days to wash your hair. This helps the curl pattern set. Until then, wear a cap when you shower.
- You may not need to shampoo every day. Many people do well washing 1 to 3 times a week. Focus on conditioning to keep hair soft.
- Try to air dry. If you use a dryer, use a diffuser and the lowest heat setting. Do not rub your hair with a towel. Gently squeeze out water instead.
- Use a wide toothed comb on damp hair. Avoid brushing dry curls because it can loosen the pattern and add frizz.
- For sleep, use a satin pillowcase. Keep hair loosely protected so curls hold their shape.
- Avoid extra heat and harsh conditions when you can. Saunas, steam rooms, and pool chlorine can dry hair. If you swim, wear a cap and rinse your hair right after.
How to Sleep with Digital Permed Hair
Sleeping habits can change how your curls look. Focus on keeping the pattern loose and uncrushed.
- Use a satin pillowcase. Satin creates less friction than cotton.
- After the first 48 hours, you can work in a light leave in conditioner and put hair in loose braids. Avoid tight braids, especially close to the scalp.
- After the first 48 hours, you can also use the “plop method.” Gather hair gently in a t shirt towel, microfiber cloth, or cotton t-shirt. Lay the fabric flat, flip hair onto the center, then wrap and secure it loosely.
