Do You Need to Use Neutralizing Shampoo after Coloring Hair? [Pros & Cons]

Did you recently color your hair? If so, your hairstylist may have recommended a neutralizing shampoo session. Neutralizing your hair is one of the most important steps of the hair coloring process.

Many people skip this step because they don’t want to spend extra money. As long as they see a new shade of color on their hair, they think they’re done.

This is a big mistake if you want healthy and shiny hair. Neutralizing your hair after exposing it to strong chemicals is not a luxury—it’s a must.

We understand that buying something you’re unsure about can be hard. That’s why we created this detailed guide. It will teach you everything you need to know about using neutralizing shampoo after coloring hair.

What Is Neutralizing Shampoo?

Neutralizing shampoo is a special type of shampoo designed to restore your hair’s pH balance after chemical treatments. It works by counteracting the high alkaline levels caused by hair color, relaxers, or perms.

Unlike regular shampoo, neutralizing shampoo contains acidic ingredients that bring your hair back to its natural, slightly acidic state. This protects your hair from damage and helps maintain its health and shine.

Do You Need to Use Neutralizing Shampoo After Coloring Hair?

Yes, you should use neutralizing shampoo after coloring your hair. Here’s why.

Hair color products open your hair cuticles and let the dye enter your hair shafts. This process creates an alkaline environment in your hair follicles. This environment is not natural or healthy for your hair.

If your hair stays in this alkaline state for too long, it can cause serious damage. Your hair may become dry, brittle, and prone to breakage.

Leaving your hair in this state is also bad for your scalp. It can lead to irritation, dryness, and even infections.

A neutralizing shampoo balances your hair’s pH by fighting the high alkaline environment. It removes harmful chemicals left behind by hair coloring products. That’s why using a neutralizing shampoo after coloring hair is so important.

What Is pH Balance and Why Does It Matter for Your Hair?

The pH scale measures how acidic or alkaline something is. It ranges from 0 to 14. A pH of 7 is neutral. Anything below 7 is acidic. Anything above 7 is alkaline.

Your hair’s natural pH is between 3.5 and 4.5. Your scalp’s pH is around 5.5. This slightly acidic state keeps your hair and scalp healthy.

When your hair is in its natural acidic state, the cuticles lie flat. This makes your hair smooth, shiny, and resistant to damage. It also protects your scalp from dandruff, bacteria, and infections.

Chemical treatments like hair coloring raise your hair’s pH above 7. This makes your hair alkaline. When your hair becomes alkaline, the cuticles open up. This leads to dryness, frizz, breakage, and dullness.

How Does Neutralizing Shampoo Restore pH Balance?

Neutralizing shampoo has a low pH, usually between 4 and 5. This acidic pH helps bring your hair back to its natural state after chemical treatments.

Here’s how it works:

• Cleanses chemical residue: It removes leftover hair dye, peroxide, and other chemicals from your hair and scalp.
• Closes the cuticles: The acidic pH helps close your hair cuticles, locking in moisture and color.
• Restores acidity: It brings your hair back to its natural pH level, making it smooth and shiny again.
• Stops ongoing damage: It stops the alkaline chemicals from continuing to break down your hair.

Without this step, your hair stays in a damaged, alkaline state. This can lead to long-term problems like thinning, breakage, and color fading.

What Happens If You Don’t Use Neutralizing Shampoo After Coloring Hair?

Skipping neutralizing shampoo can cause several problems:

1. Continued Chemical Damage

The chemicals from hair dye don’t just wash away with water. They can stay on your hair and scalp for days or even weeks. These chemicals keep working and damaging your hair even after you leave the salon.

2. Dry and Brittle Hair

An alkaline environment dries out your hair. Without neutralizing shampoo, your hair loses moisture and becomes brittle. It may start to break easily.

3. Color Fading

Open cuticles allow color molecules to escape. This makes your hair color fade faster. Neutralizing shampoo helps seal the cuticles and lock in your color.

4. Scalp Irritation

Leftover chemicals can irritate your scalp. This can cause itching, redness, flaking, and even sores.

5. Frizz and Lack of Shine

When your hair cuticles stay open, your hair looks dull and frizzy. It loses its natural shine and smoothness.

How to Choose the Best Neutralizing Shampoo for Colored Hair

There are many neutralizing shampoos on the market. Here’s how to pick the right one for your hair.

1. Check the pH Level

Look for a shampoo with a pH between 4 and 5. This range is acidic enough to neutralize alkaline chemicals but gentle enough not to damage your hair.

2. Check the Ingredients List

After coloring, your hair needs extra care. Look for shampoos with nourishing ingredients like:

• Coconut oil: Deeply conditions and repairs damage
• Shea butter: Adds moisture and strength
• Argan oil: Hydrates and adds shine
• Olive oil: Nourishes and strengthens
• Aloe vera: Soothes the scalp and moisturizes hair
• Vitamin E: Protects and adds shine
• Panthenol (Pro-Vitamin B5): Moisturizes and improves elasticity

Avoid shampoos with harsh sulfates, parabens, or alcohol. These can strip your hair and cause more damage.

3. Choose a Sulfate-Free Formula

Sulfates can strip your hair of natural oils and color. Look for a sulfate-free neutralizing shampoo to keep your hair soft and your color vibrant.

4. Choose a Shampoo That Doesn’t Lather Too Much

Many people think more lather means better cleaning. This is not true. Shampoos that create lots of foam often contain harsh chemicals that dry out your hair.

Look for a shampoo that cleans well without producing too much lather.

5. Make Sure It Offers Deep Cleansing

A good neutralizing shampoo should gently remove all product residue from your hair. It should clean both thick strands and fine baby hairs without stripping them.

6. Look for Color-Safe Formulas

Some neutralizing shampoos are made specifically for color-treated hair. These formulas protect your color while restoring pH balance.

Top 3 Recommended Neutralizing Shampoos to Use After Coloring Hair

1. Motions Active Moisture Neutralizing Shampoo

This shampoo is packed with nourishing ingredients like coconut oil, argan oil, and shea butter. These ingredients help repair damage and restore shine to chemically treated hair.

Coconut oil works as a deep conditioner. Argan oil adds hydration and shine. Shea butter strengthens your hair and protects it from future damage.

The best part? This shampoo is sulfate-free. It restores your hair’s natural pH balance without making it dull or dry. It also helps detangle your hair and gently cleanses without stripping moisture.

2. IsoPlus Neutralizing Shampoo

This shampoo has a special feature: color-changing lather. When you wash your hair, the lather turns pink if there are still chemicals left in your hair. Once the lather turns white, you know your hair is fully clean.

This takes the guesswork out of washing. You’ll know exactly when all the product residue is gone.

The shampoo is also great for people who are sensitive to fragrances. It has little to no smell. Plus, it’s affordable and budget-friendly.

3. ORS Olive Oil Professional Neutralizing Shampoo

This shampoo is enriched with olive oil, which heals, nourishes, and strengthens your hair. It gives your hair a natural shine and glow.

The thick, creamy formula detangles and hydrates your hair. It cleans all product residue without leaving your hair dry or brittle. After using it, your hair feels soft—almost like it’s already been conditioned.

It also contains aloe vera, vitamin E, and panthenol. Aloe vera soothes your scalp and moisturizes your hair. Vitamin E adds nourishment and shine. Panthenol (pro-vitamin B5) hydrates your hair shafts and improves elasticity.

A little goes a long way with this shampoo. One bottle lasts a long time.

Benefits of Using Neutralizing Shampoo After Coloring Hair

1. Stops Ongoing Chemical Damage

The chemicals in hair dye keep working even after you rinse your hair. Regular shampoo can’t remove these tough chemicals. They can cause hair breakage, scalp fungus, and allergic reactions.

Neutralizing shampoo stops this process. It removes chemical residue and prevents further damage.

2. Makes Your Hair Silky and Voluminous

Without neutralizing shampoo, your hair looks flat, dry, and greasy. Using neutralizing shampoo brings back freshness. Your hair looks fuller, shinier, and more alive.

3. Fights High Alkalinity

High alkalinity makes your hair porous and greasy. Neutralizing shampoo has a low pH that counterbalances this. It restores your hair’s natural acidity and keeps it healthy.

4. Locks in Hair Color

By closing your hair cuticles, neutralizing shampoo helps lock in your color. This keeps your color vibrant for longer and prevents fading.

5. Reduces Frizz and Adds Shine

Closed cuticles mean smoother, shinier hair. Neutralizing shampoo reduces frizz and gives your hair a healthy glow.

6. Prevents Scalp Irritation

By removing chemical residue, neutralizing shampoo protects your scalp from irritation, itching, and infections.

How to Use Neutralizing Shampoo After Coloring Hair

Follow these steps to get the best results:

Step 1: Rinse Your Hair Thoroughly

After rinsing out the hair dye, rinse your hair with lukewarm water for at least 2 to 3 minutes. This removes most of the color and chemicals.

Step 2: Apply Neutralizing Shampoo

Apply a generous amount of neutralizing shampoo to your hair. Focus on your scalp and roots, where most of the chemicals build up.

Step 3: Massage Gently

Massage the shampoo into your scalp and hair for 2 to 3 minutes. Be gentle. Your hair is fragile after coloring.

Step 4: Rinse and Repeat

Rinse your hair thoroughly. If you’re using a color-indicating shampoo like IsoPlus, check the lather. If it’s still pink, repeat the process until the lather turns white.

Step 5: Condition Your Hair

After neutralizing, apply a deep conditioner or hair mask. This adds moisture back into your hair and keeps it soft and shiny.

Step 6: Rinse with Cool Water

Finish with a cool water rinse. This helps seal the cuticles and lock in moisture and color.

Important Points to Note Before Using Neutralizing Shampoo

• Neutralizing shampoo is designed for chemically treated hair only. Use it only after coloring, perming, or relaxing your hair.

• Do not use neutralizing shampoo on untreated hair. If your hair is not chemically processed, using neutralizing shampoo regularly can make your hair too acidic. This can leave it dry and brittle.

• If you haven’t colored your hair or used any chemical treatments, use a mild, pH-balanced, sulfate-free shampoo instead. Below is a recommended option:

• Using too much neutralizing shampoo can dry out your hair. Use only the amount you need.

• Always follow up with a conditioner or hair mask to restore moisture.

How Often Should You Use Neutralizing Shampoo?

Use neutralizing shampoo only after chemical treatments like coloring, perming, or relaxing. You do not need to use it every time you wash your hair.

After the initial neutralizing session, you can use a regular color-safe or moisturizing shampoo for your daily or weekly washes.

If you retouch your color or undergo another chemical treatment, use neutralizing shampoo again.

Difference Between Neutralizing Shampoo and Clarifying Shampoo

Many people confuse neutralizing shampoo with clarifying shampoo. Both clean your hair deeply, but they serve different purposes.

Feature	Neutralizing Shampoo	Clarifying Shampoo
Purpose	Restores pH balance after chemical treatments	Removes product build-up, oil, and dirt
pH Level	Low (acidic)	Neutral to slightly alkaline
When to Use	After coloring, perming, or relaxing	Once a week or as needed
Best For	Chemically treated hair	All hair types

A clarifying shampoo only cleans. A neutralizing shampoo cleans and balances pH.

Difference Between Neutralizing Shampoo and Chelating Shampoo

Chelating shampoo is another deep-cleansing shampoo. It’s similar to neutralizing shampoo but much stronger.

Chelating shampoo removes minerals and metals from hard water, chlorine from pools, and heavy build-up. It’s often called “swimmer’s shampoo.”

These minerals can cause your hair color to fade or turn greenish. Regular shampoo and even clarifying shampoo can’t remove them. Chelating shampoo contains EDTA, which binds to these metals and removes them.

Feature	Neutralizing Shampoo	Chelating Shampoo
Purpose	Restores pH after chemical treatments	Removes minerals and metals from hard water
Key Ingredient	Acidic agents	EDTA
When to Use	After coloring or relaxing	Before coloring or after swimming
Best For	Chemically treated hair	Hard water exposure or swimmers

Can You Use Neutralizing Shampoo on Natural Hair?

If your hair is natural and has not been chemically treated, you should not use neutralizing shampoo regularly. It can make your hair too acidic and cause dryness.

However, if you have chemically treated natural hair (like relaxed or colored natural hair), neutralizing shampoo is safe and beneficial.

Are There Any Side Effects of Using Neutralizing Shampoo?

When used correctly, neutralizing shampoo is safe and beneficial. However, misuse can cause problems:

• Overuse: Using it too often can strip your hair of natural oils and make it dry.
• Using on untreated hair: This can make your hair too acidic and brittle.
• Not following with conditioner: Skipping conditioner after neutralizing can leave your hair rough and tangled.

Always use neutralizing shampoo only after chemical treatments and follow up with a moisturizing conditioner.

DIY Neutralizing Shampoo: Can You Make It at Home?

If you want a natural option, you can make a simple neutralizing rinse at home using apple cider vinegar (ACV).

Apple Cider Vinegar Rinse

• Mix 2 tablespoons of apple cider vinegar with 1 cup of water.
• After shampooing, pour the mixture over your hair.
• Let it sit for 2 to 3 minutes.
• Rinse thoroughly with cool water.

Apple cider vinegar is acidic and helps lower your hair’s pH. However, it’s not as strong as a commercial neutralizing shampoo. It works well for mild pH balancing but may not fully remove chemical residue.

Tips for Maintaining Healthy Hair After Coloring

• Use a neutralizing shampoo immediately after coloring.
• Follow up with a deep conditioner or hair mask.
• Avoid washing your hair for 48 hours after coloring to let the color fully set.
• Use sulfate-free, color-safe shampoos for regular washing.
• Limit heat styling. Use a heat protectant if you must use hot tools.
• Get regular trims to remove split ends and keep your hair healthy.
• Protect your hair from the sun with hats or UV-protectant sprays.
• Drink plenty of water and eat a balanced diet to nourish your hair from the inside.
