Let’s be honest-keeping purple hair from fading into a sad, brassy mess is a part-time job. You wash it, and poof, there goes another chunk of your vibrant investment down the drain. I’ve been there, staring at the shower floor wondering if it’s worth it. That’s where a great color depositing shampoo comes in. It’s not just a cleanser; it’s a color refresher, a conditioner, and a sanity-saver all in one bottle.
But here’s the rub: not all purple shampoos are created equal. Some deposit a gorgeous, rich violet, while others leave a weird blue tint or dry your hair out like straw. After testing the most popular options, I’ve found the ones that actually work-the shampoos that keep your purple looking salon-fresh for weeks, not days. This guide cuts through the hype to show you what really performs.

Complete Buyer's Guide: How to Choose a Purple Color Depositing Shampoo
1. Understand Your Hair's Starting Point
This is the most critical factor. Color depositing shampoos work best on pre-lightened, bleached, or light blonde hair (level 7 and above). On dark brown or black hair that hasn’t been lightened, you’ll see little to no purple tint. For gray or white hair, they can work wonders, depositing a beautiful, even color.
2. Decide Between Maintenance and Transformation
Are you looking to refresh fading color or do a full color change? For weekly maintenance, a liquid shampoo like Watercolors is perfect. For a more dramatic, lasting result (like covering grays), a cream formula or 3-in-1 dye shampoo like TYAYW’s option is better suited. Check how long you need to leave it on-quick 5-minute washes vs. 30-minute treatments offer very different results.
3. Prioritize Hair Health with Ingredients
Look for formulas that condition as they color. Ingredients like bond builders (e.g., BondHeal), keratin, coconut oil, and argan oil help counteract the drying effect some direct dyes can have. Avoid shampoos with sulfates if you have dry or color-treated hair, as they can strip color and moisture.
4. Consider Longevity and Fading
Some shampoos, like NO FADE FRESH, are designed to fade ‘on-tone,’ meaning the color diminishes evenly without turning strange colors. Others might wash out completely after a few showers. If you hate patchy color, look for this feature. Also, note that no depositing shampoo is permanent; even the best need regular use.
5. Ease of Use and Clean-Up
Think about your routine. Do you want a simple lather-rinse process, or are you okay with a longer treatment? Also, check if the product is known to stain hands, towels, or shower surfaces. Most quality options rinse clean, but it’s always a good check in user reviews.
6. pH Balance and Scalp Health
A shampoo with a pH around 5.3-5.8 (like MyColorIn’s) is ideal. This mild acidity helps seal the hair cuticle for shine, reduces scalp irritation, and helps the color adhere better. It’s a sign of a well-formulated product that cares for your hair’s health.
Frequently Asked Questions
1. How often should I use a purple color depositing shampoo?
It depends on your hair color goals and the product’s strength. For maintaining vibrant color, using it once or twice a week instead of your regular shampoo is usually perfect. If you’re using a stronger, 3-in-1 dye shampoo (like the TYAYW option), you might only need it every 3-4 weeks for a full refresh. Overuse can lead to buildup or overly intense color, so start slow!
2. Can I use it on non-bleached or dark hair?
You can, but temper your expectations. On dark brown or black hair that hasn’t been lightened, the purple pigment likely won’t show up at all. These shampoos are designed to deposit color on a light canvas. You might see a slight tint in direct sunlight, but for a true purple, pre-lightening is necessary.
3. Will it stain my skin, towels, or shower?
Most modern formulas are designed to rinse clean from skin and surfaces. However, it’s always smart to use gloves during application and rinse your shower promptly after use. Some richer, creamier formulas (like NO FADE FRESH) have a higher chance of leaving a temporary tint if not fully rinsed. Always do a strand test first!
4. Is a color depositing shampoo damaging to hair?
Generally, they are much less damaging than permanent dyes because they contain no ammonia or peroxide. They simply coat the hair shaft with pigment. However, some can be drying. That’s why choosing a formula with conditioning ingredients (oils, bond builders) is key to keeping your hair healthy and strong while you color it.
Final Verdict
Keeping purple hair vibrant doesn’t have to be a constant battle. The right color depositing shampoo makes all the difference. For most people, the Watercolors Intense Shampoo is the undisputed champion-it’s reliable, effective, and simplifies your routine. If you’re on a tight budget but still want great results, the TYAYW 3-in-1 Shampoo offers incredible value and long-lasting color. And if your hair needs some TLC, the NO FADE FRESH shampoo with bond repair is a game-changer. Whichever you choose, you’re just a wash away from brighter, bolder, beautiful purple hair.
