You’ve probably been staring at those dreamy curls on Instagram or maybe just walked out of the salon with a fresh new look. Either way, one big question is on your mind — how long does a perm last?
Basically, most perms last around three to six months, depending on your hair and how you treat it. But honestly, there’s a lot more to it than just time. Different types of perms, your haircare habits, and even your daily routine can change everything.
So if you want to keep those curls looking fresh and full for as long as possible, let’s talk.
What is a Perm?
A perm, short for permanent wave, is a chemical treatment that changes the natural structure of your hair. It can make straight hair curly or wavy, depending on the type of perm you choose.
There are different styles like:
| Perm Type | Look It Creates |
| Loose Perm | Soft beachy waves |
| Curly Perm | Tight, bouncy curls |
| Wavy Hair Perm | Natural wave look |
| Mens Perm | Curled or waved look for guys |
| Black Perm | Curly styles for Black hair textures |
| Permanent Wavy Perm | Long-lasting soft waves |
How Long Does a Perm Last?
So, how long does a permanent wave last? A perm usually lasts 3 to 6 months. But this can change depending on:
- Your hair type (thick, thin, straight, curly)
- The type of perm you get (hot or cold)
- How well you take care of your hair after the perm.
Here’s a quick look:
| Hair Type | Expected Longevity |
| Thick Hair | 4 to 6 months |
| Thin/Fine Hair | 2.5 to 4 months |
| Dry/Damaged Hair | 2 to 3 months |
| Colored Hair | 2 to 4 months |
| Natural Healthy Hair | 5 to 6 months |
Hot Perm vs Cold Perm
There are mainly two types of perms—hot perm and cold perm.
A hot perm, also called a digital perm, uses heat and special rods with an acid-based solution to give you soft, natural-looking curls. These curls usually look more flowy and relaxed, and they need a bit of care to keep them looking nice.
On the other hand, a cold perm, sometimes called a ceramic perm, doesn’t use heat. It uses a different solution that gives you tighter, more old-school curls. These curls are easier to look after and usually last longer with less work.
Factors That Affect How Long a Perm Lasts
Here are the main things that make your perm last longer (or shorter):
- Stylist Experience: A good stylist means a good perm! They know how to use the right chemicals for your hair type.
- Hair Health Before Perming: If your hair is already damaged, the perm may not hold well. Avoid coloring or bleaching before your appointment.
- Your Lifestyle: If you swim a lot, sweat daily, or shampoo often, your perm will wear off faster.
- Product Quality: Cheap products with harsh chemicals or sulfates will ruin your curls. Use gentle, moisturizing products.
Perm Before and After: What to Expect
Before a perm:
- Hair is straight or lightly wavy
- Needs to be healthy and free of color damage.
After a perm:
- You’ll see curls or waves set in
- Hair feels textured, may feel drier at first
- No washing or touching for 48 hours (this is very important!)
Using the right products makes a big difference. Here’s a list of the best shampoos and conditioners for curly and wavy hair.

Who Can Get a Perm?
Let’s talk about who can actually get a perm, because it’s not always one-size-fits-all.
First, let’s look at hair length. If your hair is short to medium length, that’s perfect. It’s easier to wrap around the rods and takes less time. Long hair can definitely be permed, too, but just know that it might take longer in the salon and needs more even application to look good all over.
Now, about hair texture. Perms work best on thick, healthy hair because it can handle the chemicals better and holds the shape longer. If your hair is very fine or naturally super straight, you might still be able to get a perm, but it usually takes more effort and care, so you’ll want a stylist who knows what they’re doing.
And finally, if your hair is already colored, that’s something to think about. You can get a perm on colored hair, but if you have highlights, especially bleach, your hair might frizz or get dry faster. It’s usually safer to perm hair that’s fully dyed rather than just highlighted. Your stylist can help check your hair’s condition and tell you what’s best.
So yes, most people can get a perm. You just need to make sure your hair is in good enough shape and pick the right type for you.
Wrapping Up
A perm is a fun and stylish way to switch up your hair. If you’re going for a wavy hair perm, a black perm, or a trendy men’s perm, knowing how long a perm lasts and how to care for it is super important. Most perms last 3 to 6 months, but with the right care, they can stay beautiful even longer.
Quick Reminder:
- Choose the right stylist
- Use proper hair products
- Treat your hair gently
- Enjoy your new look!
So, now that you know what perm is and everything else about it, are you ready to get those dreamy curls?
