Have you made the switch to natural hair dye? That’s great news for your hair, your health, and the planet. Natural hair dyes not only offer rich, vibrant shades and excellent grey coverage, but they also act as a complete care treatment for your hair.

Now that you’ve taken the leap, one important question probably comes to mind: What shampoo should you use after a natural hair dye? And it’s a very good question! The shampoo you choose will make all the difference in preserving your gorgeous color.

In this article, we’ll walk you through everything you need to know and help you choose the best shampoo for natural hair dye care!

Natural hair dye shampoo: why ingredients matter!

To maintain your natural hair dye, there’s one essential rule to follow: always care for your color with natural treatments and gentle shampoos. A shampoo that contains harsh chemicals won’t just damage your hair, it will also strip away your color in no time.

That’s why choosing the right shampoo for natural hair dye starts with reading the label and paying close attention to the ingredient list.

Ingredients to avoid in a shampoo for natural hair dye

Many ingredients commonly found in conventional shampoos (the polite way to say chemical shampoos!) can negatively impact the durability, intensity, or overall quality of your natural hair color. Here are the key ones to avoid:

Harsh surfactants

Sulfates like Sodium Laureth Sulfate (SLES) or Sodium Lauryl Sulfate (SLS) are often used for their foaming power. Unfortunately, they are also highly stripping, which can quickly fade your color and disrupt your scalp’s natural balance.

Silicones

Often added to give hair a smooth and shiny appearance, silicones, such as Dimethicone or Cyclopentasiloxane, form an occlusive film that prevents plant-based pigments from penetrating the hair fiber. This artificial barrier interferes with the effectiveness of natural hair care treatments.

Quats and derivatives (quaternary ammonium compounds)

Ingredients like Behentrimonium Chloride or Polyquaternium-10 are used to detangle and soften hair. However, they coat the hair shaft and can hinder the adhesion of natural color pigments. In addition, they are poorly biodegradable, which goes against the eco-friendly values of natural hair dye.

Denatured alcohols and aggressive preservatives

Certain drying alcohols (such as Alcohol Denat.) and harsh preservatives (like Phenoxyethanol) can weaken the hair fiber and irritate the scalp, compromising its ability to absorb and retain plant-based pigments effectively.

Ingredients to look for

On the flip side, some ingredients are highly compatible with natural hair dye because they respect the hair fiber, enhance the color, and help it last longer over time. Here are the ones you should look out for:

Mild and natural cleansing agents

Opt for gentle, sulfate-free surfactants such as Disodium Cocoyl Glutamate, derived from a reaction between amino acids and coconut oil, or plant-based cleansers like soapnut (Sapindus mukorossi). Other gentle options include sugar-based or papaya-derived surfactants.

These natural-origin cleansing agents clean the hair gently, without stripping the color or irritating the scalp.

Strengthening botanical ingredients

Some plants naturally strengthen the hair fiber and help prolong the intensity of the color. Look for ingredients like Aloe vera juice (hydrating, soothing), Roman chamomile (shine and brightness), rosemary (toning, balancing), and rice proteins, to name just a few.

Lightweight plant oils

Oils like jojoba, argan, and olive are ideal for hair care. They nourish the hair without weighing it down or clogging it. These oils are true treasures for fortifying the hair, and healthy hair means longer-lasting color!

Gentle, natural preservatives

Preservatives such as Sodium Benzoate or Potassium Sorbate are ideal for ensuring product stability without irritating or disrupting the scalp’s natural balance.

What pH level is best for a shampoo compatible with natural hair dye?

The pH level of your shampoo plays a crucial role in the longevity and quality of your natural hair color. An unsuitable pH can overly open the hair cuticle, weaken the color, or even interfere with the lasting power of henna and other plant-based dyes. That’s why you should be cautious with solid shampoos marketed for natural hair dye, they’re often poorly adapted due to the difficulty of pH regulation in solid formats.

The ideal pH to aim for?

A slightly acidic pH, ideally between 4.5 and 5.5, is perfect for:

Respecting the scalp’s natural balance
Sealing the hair cuticles after coloring
Helping plant pigments bind more effectively
Preserving shine and vibrancy in the hair fiber

On the other hand, a shampoo with a too alkaline pH (above 7) can make hair porous, leading to quicker fading, a dull appearance, and more difficult-to-manage hair.

To make things easier, all Hairborist shampoos are formulated with a pH that’s perfectly adapted to both the hair and the scalp, so you can care for your color with complete peace of mind.

First shampoo after natural hair dye: why timing matters

Did you know that the color you see right after applying your natural hair dye isn’t final yet? That’s right—it’s completely normal! The color continues to develop over the 48 hours following the application.

Why is that? Because natural hair dye works through natural oxidation. This means the pigments gradually bind to the hair as they’re exposed to air, causing the color to darken slightly and reveal its full depth over time.

The only way to interrupt this oxidation phase is… by shampooing. That’s why your plant-based hair stylist won’t always wash your hair after the color is applied. Instead, they’ll carefully rinse it and apply a color-setting treatment like Natural Color, which contains apple cider vinegar. If the result after rinsing already matches your desired color, a shampoo might be done. Otherwise, it’s best to let the color evolve naturally to achieve the perfect shade.

Timing is everything.

For best results, it’s generally recommended to wait 48 hours before your first shampoo after natural hair dye. This allows for optimal pigment fixation, controlled intensity, and a color that’s fully developed and long-lasting.

Still unsure? Have questions about when to wash your hair? Talk to your plant-based hair colorist! They’ll guide you toward the best post-color care routine based on your hair type, your chosen shade, and your goals.

Choosing the right shampoo for natural hair dye is key, but it’s not the only thing!

Yes, picking the right shampoo is essential to maintain a vibrant, intense result but that’s just the beginning!

When you switch to natural hair care, your entire routine needs to follow suit to ensure the best possible results. As experts in natural hair dye for over 30 years, we’ve had plenty of time to craft the perfect routine to care for your natural hair color. With just three simple steps, your hair and your color will be in their best shape ever.

The oil bath: a natural color booster

Kick off your natural hair dye care routine with an intense, organic oil bath, tailored to your specific hair color. At Hairborist, we offer two oil bath bases that can be customized with Aromasynergies : powerful blends of essential oils that enhance and personalize your treatment.

For the base of your pre-shampoo treatment, we recommend using Renovator. Certified organic, it provides deep nourishment, hydration, and a radiant shine, making it the ideal foundation for vibrant hair color care.

To customize your oil bath, simply add one of the following essential oil synergies depending on your shade:

Nacre : For blond hair, this blend acts like a natural “purple shampoo,” helping to neutralize yellow tones and correct unwanted highlights.
Cuivre : Perfect for maintaining the intensity and richness of copper shades.
Ébène : Enhances and deepens dark colors like browns and blacks.
Écarlate : Keeps red shades bold, radiant, and full of life.

Mix 10 drops of your chosen synergy with the Renovator oil bath to create a customized treatment that enhances and preserves your color’s brilliance. Apply to dry hair before shampooing, and let it sit for 7 to 15 minutes for best results.

Choosing the right shampoo for natural hair color

After your color-enhancing oil bath, it’s time for the shampoo step, which, as mentioned at the beginning of this article, must be gentle and well-suited to your needs. At Hairborist, we offer three organic shampoos that are fully compatible with natural hair dye, so you can choose the one that best fits your preferences and hair type:

Its washing base is organic soapnut, making it suitable for daily use, in fact, that’s exactly what it was created for. Its ultra-soft formula is perfect for preserving the brilliance of your natural hair dye.

Final step: the right conditioner for natural hair dye

Conditioner is a key step in any natural hair color care routine. It helps seal the hair cuticle after shampooing, which locks in the benefits of your treatments, secures the color pigments, and adds an extra boost of shine and hydration.

For hair colored with natural dyes, Hairborist offers two different conditioners, each tailored to specific hair types:

Natural Color : Made with organic apple cider vinegar, Natural Color helps fix the pigments in the hair and delivers exceptional shine. This spray-on conditioner foams when emulsified and is ideal for normal to fine hair. It’s the perfect finishing touch after washing colored hair.
Le Sweet Care : Formulated with mallow and aloe vera, Sweet Care is a richer, cream-based organic conditioner. It’s especially suited for normal to thick hair, providing deep nourishment, softness, and long-lasting hydration.

You now have everything you need to choose the ideal natural hair dye shampoo and care routine, tailored to your specific needs and hair type. By incorporating these products into a consistent and natural hair care regimen, you’ll enjoy vibrant, glossy, and long-lasting color, while also respecting the health of your scalp and the planet.
