You finally did it. You sat in that salon chair for four hours, braved the bleach, and emerged with the perfect shade of amethyst. Or maybe it’s a deep plum. Either way, you look incredible. Then you hit the shower. Suddenly, your expensive purple dye is swirling down the drain, and your once-springy curls feel like a bundle of dry hay. It’s frustrating.
Maintaining purple curly hair is basically like a full-time job you didn't apply for.
The struggle is real because you’re fighting two different battles at once. On one hand, curly hair is naturally porous and craves moisture. On the other, purple pigment—especially the semi-permanent kind used for "fashion" colors—is notoriously slippery. It doesn't want to stay in the hair shaft. When you use the wrong purple curly hair products, you end up with muddy, greyish hair that has zero bounce.
The Chemistry of Why Your Purple Curls Are Failing
Curly hair has an elliptical follicle shape. This makes it harder for natural oils from your scalp to travel down the hair strand. That’s why you’re always dry. Now, add bleach into the mix. To get that vibrant purple, most stylists have to lift your hair to a level 9 or 10 blonde. This process "blows open" the cuticle. While this makes the hair take color easily, it also makes it let go of that color the second you use a harsh sulfate shampoo.
Sulfates are basically dish soap for your head. Sodium Lauryl Sulfate (SLS) is great at cleaning grease off a pan, but it’s a nightmare for a purple wash.
Most people reach for a "Purple Shampoo" to fix this. Stop. That’s probably your first mistake. Standard purple shampoos (like the famous Clairol Professional Shimmer Lights) are designed for blonde hair. They contain crushed violet pigments meant to neutralize yellow tones. They are often very drying. If you have purple-dyed curls, using a blonde-toning shampoo can actually strip your actual purple dye while drying out your curl pattern. You don't want to neutralize yellow; you want to deposit purple.

Look for Color-Depositing Conditioners Instead
If you want to keep the vibrancy without the crunch, you need to switch to color-depositing products. Brands like Overtone or Celeb Luxury Viral Colorwash are the gold standards here. Specifically, the Overtone Coloring Conditioners are thick, almost like a mask. They use shea butter and coconut oil as a base. This satisfies the "curly" requirement of moisture while shoved-full of pigment.
I’ve seen people use the "Extreme Purple" shade from Overtone and literally skip their salon refresh for three months. It’s that potent. But be careful. If you use it every single wash, you might get "pigment pill-up," where the hair starts to look dark and dull because there's too much product on the cuticle.
Ingredients That Actually Matter for Your Pattern
Forget the marketing fluff on the front of the bottle. Turn it over. You want to see "Film-Forming Humectants." These are the holy grail for purple curly hair products. Ingredients like Flaxseed gel, Marshmallow root, and Hydrolyzed Quinoa protein are vital.
Why? Because they create a microscopic barrier around the hair strand. This barrier does two things:
- It traps moisture inside so your curls stay clumped and defined.
- It keeps the purple pigment from leaching out every time it gets wet.
Avoid heavy silicones like Dimethicone if you follow the Curly Girl Method (CGM). While silicones give a temporary "fake" shine, they require sulfates to remove. Since we already established that sulfates kill purple dye, you’re stuck in a vicious cycle. If you use silicones, you have to use sulfates. If you use sulfates, your purple disappears. It’s a losing game.

The Low-Poo vs. No-Poo Debate
For purple curls, "Co-washing" (washing with only conditioner) is often recommended. Honestly? It's a bit of a gamble. While it saves your color, it can lead to scalp buildup, which causes itching and can even stunt hair growth. A "Low-Poo" like the Jessicurl Gentle Lather Shampoo is a better middle ground. It’s color-safe and won't leave you feeling greasy.
How to Build a Routine That Doesn't Suck
The order of operations matters more than the price of the bottle. You can't just slap on some purple goo and hope for the best.
First, temperature. Cold water is your best friend. It’s miserable, I know. But hot water lifts the hair cuticle. If you wash your purple curls in a steaming hot shower, you are essentially opening the door and inviting the color to leave. Use lukewarm water for the wash and ice-cold water for the final rinse. It seals the cuticle and adds a natural shine that no spray can mimic.
Deep Conditioning is Non-Negotiable
Once a week, you need a heavy hitter. The Briogeo Don’t Despair, Repair! mask is a cult favorite for a reason. It’s balanced. It has protein to strengthen the bleached strands and oils to soften them. If your hair feels "mushy" when wet, you need more protein. If it feels like straw and snaps easily, you need more moisture.
Styling Without Fading
Your leave-in conditioner and gel are your final line of defense. Look for products with UV inhibitors. Just like the sun bleaches a deck, it will bleach your purple hair. Uncle Funky’s Daughter Curly Magic is a great botanical gel that plays well with colored hair. It’s aloe-based, so it’s hydrating, and it doesn't have the harsh alcohols that some cheap gels use to provide "mega hold."

Real Talk: The Cost of the "Vivid" Life
Let's be real. Purple hair is expensive. Between the initial lightening and the maintenance of high-end purple curly hair products, you’re looking at a significant investment.
Many people try to save money by mixing a cheap semi-permanent dye (like Arctic Fox Purple AF) into their regular conditioner. This is actually a brilliant "pro-tip" that most stylists won't tell you. It works. It’s essentially what the expensive brands are selling you, just DIY. Use about a 1:4 ratio of dye to conditioner. Just make sure the conditioner is white—if you mix purple dye into a yellow or orange conditioner, you’re going to get a brown, muddy mess.
Common Misconceptions About Purple Curls
Most people think that because their hair is "dyed," they shouldn't use protein treatments. That’s wrong. Bleached hair—which purple hair almost always is—is fundamentally missing the structural integrity of healthy hair. It has "gaps" in the protein structure. If you don't fill those gaps with something like Aphogee 2-Step Protein Treatment (sparingly!) or a lighter protein cream, your curls will simply lose their "memory" and go limp.
Another myth is that all purple hair fades to a "pretty lavender." It doesn't. Depending on the base tones of your hair and the brand of dye, it can fade to a swampy green or a weird, patchy grey. This is why using a dedicated color-depositing product once every two weeks is better than trying to "fix" it once it’s already faded.
Making Your Purple Last
If you're serious about this color, you need to change your lifestyle slightly.
- Dry Shampoo: Get used to it. The less you wash, the longer the purple stays. Batiste is fine, but Not Your Mother’s has some great unscented options that won't compete with your perfume.
- Silk Pillowcases: Cotton is an absorbent material. It literally sucks the oils and some of the pigment out of your hair while you sleep. A 100% Mulberry silk pillowcase (not satin, which is often polyester) reduces friction and helps keep the hair cuticle flat.
- Plopping: If you’re a curlie, you know about plopping. Use a microfiber towel or an old T-shirt. Terry cloth towels have tiny loops that hook into your curls and tear the cuticle, causing frizz and color loss.
Actionable Steps for Your Next Wash Day
- Pre-Poo: Apply a light oil like Jojoba to your ends before you even get in the shower. This acts as a water-repellant and minimizes the amount of "swelling" the hair does when wet, which protects the color.
- Cleanse: Use a sulfate-free, low-lather cleanser. Focus only on the scalp. Let the suds run down the ends; don't scrub them.
- Deposit: Apply your color-depositing conditioner. Comb it through with a wide-tooth comb or a Denman brush to ensure every curl is coated. Let it sit for at least 10 minutes.
- Seal: Rinse with the coldest water you can stand.
- Style: Apply a leave-in conditioner followed by a hard-hold gel while the hair is still soaking wet. Scrunch carefully.
- Dry: Air dry or use a diffuser on the "cool" or "low" setting. High heat is the enemy of purple pigment.
Keeping purple curly hair vibrant requires a shift in how you view "clean" hair. It's less about stripping away the dirt and more about preserving the delicate balance of pigment and moisture. If you treat your hair like a delicate silk fabric rather than a rugged rug, your color—and your curls—will actually last.
