Honestly, perms used to have a bad reputation. Mention the word and most people immediately picture the stiff, crunchy, poodle-like frizz of the 1980s. But things have changed. A lot. Modern hair chemistry has evolved to the point where "perm" doesn't just mean one thing anymore. Whether you’re looking for effortless beach waves or tight, defined coils, understanding the different types of hair perms with pictures is basically the only way to make sure you don't walk out of the salon looking like a vintage yearbook photo.
Perming is a chemical process. It’s science. You're literally breaking the disulfide bonds in your hair and reforming them around a rod or tool. Because this process is permanent—hence the name—you really can't afford to wing it.
The Digital Perm vs. The Cold Perm: Why Chemistry Matters
Most people don't realize that the biggest difference in perms isn't just the rod size. It's the temperature.
The Digital (Hot) Perm
Born in Japan and perfected in Korea, the digital perm is the king of the "lived-in" look. Your stylist applies a relaxing solution, then winds your hair onto heated rollers that are literally plugged into a machine. This machine regulates the temperature digitally. It’s high-tech.
The result? Waves that look better when the hair is dry. Unlike traditional perms that can look a bit frizzy if you don't load them with product, a digital perm creates soft, bouncy curls that look like you just spent forty minutes with a curling iron. It works best on thick, straight hair. If you have fine, limp hair, the heat might be a bit much, and the curls might not "pop" as well.
The Traditional Cold Perm
This is the classic. No machines, no heat. The hair is soaked in an alkaline solution (usually containing ammonium thioglycolate) and wrapped around plastic rods. Cold perms are better for getting curls right at the root. If you want maximum volume or a tighter curl pattern, this is usually the way to go. It’s also generally faster than a digital perm, though the "wet look" is more prominent here. When the hair dries, the curl can sometimes lose a bit of its definition unless you use a good diffuser.

Breaking Down the Aesthetic: Types of Hair Perms With Pictures in Mind
When you’re scrolling through Instagram looking for types of hair perms with pictures, you’ll see a few specific styles popping up over and over. Here is what they actually are in real-world terms.
The Spiral Perm
Think 90s glam. This involves setting the rods vertically. Instead of rolling the hair up toward the scalp, the hair is wrapped around a long, thin rod in a corkscrew motion. This creates a very defined, springy curl. It’s high maintenance. You’ll need a lot of curl cream. But for someone with long hair who wants that "wow" factor, it's unbeatable.
The Body Wave
This is for the person who doesn't actually want "curls." They want movement. Using large rollers, the stylist creates a loose, rolling wave. It’s great for adding volume to thin hair that usually just hangs there. It’s the "I woke up like this" of the perm world. It won't give you ringlets, but it will give you texture.
The Multi-Textured Perm
Nature isn't perfect. Real curly hair doesn't have the exact same curl pattern all over the head. The multi-textured perm mimics this by using a variety of different rod sizes. It looks incredibly natural. By mixing smaller rods near the nape and larger ones on top, you avoid that "uniform" look that screams "I just got a perm."

It's not all fun and games. Perming is a controlled form of hair damage.

According to trichologists, the health of your cuticle determines how well the perm takes. If your hair is heavily bleached or "high porosity," the chemical solution might rush in too fast and snap the hair. This is why a "strand test" is non-negotiable.
Pro Tip: If your stylist doesn't offer a strand test and your hair is color-treated, run. Honestly.
- Virgin Hair: Takes perms the best. The bonds are strong and predictable.
- Color-Treated Hair: Requires a "buffered" or acid-balanced perm solution to prevent over-processing.
- Bleached Hair: Usually a no-go. The disulfide bonds are already compromised. Adding a perm to platinum hair often results in a "melted" texture.
Maintaining the Vibe: The First 48 Hours
You've heard it in Legally Blonde, and it’s true: don't wash your hair.
The chemical bonds need time to solidify in their new shape. If you jump in the shower or go for a swim 12 hours after your appointment, you’re basically washing your money down the drain. You should also avoid heavy clips or tight ponytails, which can leave a permanent "dent" in the soft, newly formed curls.

The Root Perm
If your hair is flat at the top but you like your straight ends, a root perm just targets the first two inches of growth. It's a secret weapon for people with fine hair who are tired of using volumizing sprays every single morning.
The Spot Perm
Maybe you have one section of hair that is weirdly straight while the rest is wavy. A spot perm fixes that specific area to match the rest of your head. It’s surgical. It’s precise. It’s a lifesaver for people with cowlicks.
Why the "Man Perm" Is Exploding
We have to talk about the "merm" or man perm. It’s huge right now. Specifically, the "broccoli cut" or the curly top with faded sides. Young men are flocking to salons to get texture on top. Because the hair is usually shorter, these perms are easy to maintain and grow out quickly. It’s a low-risk way to completely change a silhouette.
How to Talk to Your Stylist
Don't just say "I want a perm." That’s like going to a restaurant and saying "I want food."
Bring the types of hair perms with pictures you’ve saved. Point to specific things. "I like the wave here, but I don't want the volume there." Be honest about your hair history. If you used a box dye six months ago, tell them. If you use a flat iron every day, tell them. The more they know, the better they can adjust the chemical strength.
Actionable Steps for Your Perm Journey
- The Porosity Test: Drop a strand of your clean hair into a glass of water. If it sinks immediately, your hair is highly porous and might be too damaged for a perm. If it floats, you’re likely good to go.
- Sulfate-Free Shopping: Before your appointment, buy a sulfate-free shampoo. Sulfates are harsh detergents that will strip the moisture out of your new curls and make them look frizzy.
- Protein vs. Moisture: Permed hair needs a balance. Look for products containing keratin to strengthen the bonds and jojoba or argan oil to keep the "cortex" hydrated.
- The Silk Pillowcase: It sounds extra, but friction is the enemy of a perm. Sleeping on silk or satin prevents the hair from tangling and breaking overnight.
- Ditch the Brush: Once you have a perm, your brush is for the bin. Use a wide-tooth comb or just your fingers. Brushing breaks up the curl clumps and creates a giant cloud of frizz.
Getting a perm is a commitment. It changes your routine and how you see yourself in the mirror. But with the right technique and a clear understanding of the options, it’s one of the best ways to add permanent style and "oomph" to hair that feels boring. Just remember: moisture is your new best friend. Without it, even the best perm will eventually lose its luster. Keep it hydrated, leave it alone for the first two days, and enjoy the texture.
