How Long Should You Wait to Dye Your Hair After a Relaxer?

Are you planning to dye your hair after getting a relaxer? You can definitely do it to give yourself a fresh, new look. Dyeing your hair after relaxing it can instantly add vibrancy to your overall appearance and help you stand out.

Dyeing after a relaxer is a fun way to experiment with your style. It gives you a beautiful mane and boosts your confidence. However, both relaxers and dyes contain chemicals that can harm your hair and scalp if not used correctly.

Transforming your hair sounds exciting, but it also requires proper care, protection, and patience. If you’re thinking about dyeing your hair on the same day you relax it, stop right there. Beauty should never come at the cost of damaging your hair.

This detailed guide will walk you through everything you need to know about safely dyeing your hair after a relaxer, including timing, best practices, product recommendations, and maintenance tips.

What Is a Hair Relaxer and How Does It Work?

A hair relaxer is a chemical treatment used to straighten curly, coily, or textured hair. It works by breaking down the protein bonds in your hair shaft, permanently altering its structure.

Relaxers typically contain strong alkaline chemicals like sodium hydroxide (lye) or calcium hydroxide (no-lye). These chemicals penetrate the hair cuticle and break disulfide bonds, which give hair its natural curl pattern.

Once these bonds are broken, your hair becomes straighter and more manageable. However, this process also makes your hair more porous and vulnerable to damage.

Types of Relaxers

• Lye relaxers: Contain sodium hydroxide. They work faster but can be harsher on the scalp.
• No-lye relaxers: Contain calcium hydroxide or guanidine hydroxide. They are gentler on the scalp but can leave hair drier.
• Thio relaxers: Contain thioglycolate. They are milder and often used for fine or color-treated hair.

How Relaxers Affect Hair Structure

Relaxers remove approximately 30% of the hair’s cuticle layer. This makes the hair shaft more porous and susceptible to moisture loss, breakage, and chemical damage. Understanding this is crucial when planning to add another chemical process like dyeing.

Can You Dye Your Hair After a Relaxer?

Yes, you can dye your hair after a relaxer. Don’t let myths about dyes and relaxers stop you from achieving your dream look. However, you must follow important guidelines to ensure a safe and successful hair transformation.

Both relaxing and dyeing are chemical processes that alter your hair’s structure. When done improperly or too close together, they can cause severe damage, including breakage, dryness, and scalp irritation.

1. Consider the Porosity of Your Hair

Check your hair’s porosity and elasticity before dyeing. These tests help you determine if your hair is healthy enough to withstand another chemical treatment.

How to test hair porosity:

• Take a clean, dry strand of hair
• Place it in a glass of room-temperature water
• Wait 2-4 minutes and observe:
  • Floats on top: Low porosity (healthy cuticle layer)
  • Sinks slowly: Normal porosity (ideal for dyeing)
  • Sinks immediately: High porosity (damaged, may not hold color well)

How to test hair elasticity:

• Take a wet strand of hair
• Gently stretch it
• Healthy hair stretches and returns to normal
• Damaged hair breaks immediately or doesn’t return to its original length

If your hair strand breaks easily during the elasticity test, skip dyeing until your hair recovers. Hair health is more important than color.

2. Consider the Correct Volume of Developer

Be careful when choosing the right volume of developer for relaxed hair. A developer helps hair dye penetrate the cuticle layer by opening it up.

Since relaxers already remove about 30% of the cuticle layer, your hair is already more porous than virgin hair. Using the developer volume recommended for virgin hair will over-process your relaxed hair and cause damage.

Developer volume guide for relaxed hair:

Purpose	Recommended Volume
To lighten hair	20 volume (use with caution)
To deepen hair color	10 volume
To match current color	10 volume
To deposit color only	10 volume or no developer
To cover more than 30% gray	20 volume (monitor closely)
To cover less than 30% gray	10 volume

For relaxed hair, it’s safer to use a lower volume developer (10 volume) whenever possible. If you must use 20 volume, watch the processing time carefully and rinse as soon as you achieve the desired color.

3. Consider the Processing Time

Dyeing relaxed hair takes less processing time than dyeing virgin hair. The increased porosity means the dye penetrates faster.

Typical processing times:

• Virgin hair: 30-45 minutes
• Relaxed hair: 20-30 minutes

The exact time depends on your hair type, thickness, and the specific dye product. Leaving dye on longer than needed will over-process your hair and cause breakage.

Always do a strand test first. Apply the dye to a small, hidden section of hair to determine the correct processing time and check the final color result.

4. Consider Your Scalp Sensitivity to the Dye Formula

Scalp sensitivity is common, especially after a relaxer treatment. Your scalp may still be recovering from the relaxer’s harsh chemicals.

How to do a patch test:

• Mix a small amount of the hair dye according to instructions
• Apply it to your inner wrist or behind your ear
• Wait 24-48 hours
• Check for redness, itching, swelling, or burning

If you experience any allergic reaction, do not use that dye. Try a different brand or formula, or consider semi-permanent dyes, which are gentler.

5. Consider Hydrating Your Hair with Treatments and Masks

Curly and coiled hair types are naturally dry. Chemical treatments like relaxers and dyes make them even drier. Extra hydration and moisture are essential.

Use protein treatments and deep conditioning hair masks designed for color-treated or chemically processed hair. Apply these treatments weekly to maintain shine, strength, and health.

Recommended treatments:

• Protein treatments (once a month to rebuild strength)
• Deep conditioning masks (weekly for moisture)
• Leave-in conditioners (daily for protection)
• Hot oil treatments (bi-weekly for added hydration)

How Long Should You Wait to Dye Your Hair After a Relaxer?

You should wait at least 7-14 days before dyeing your hair after a relaxer. Ideally, wait two weeks for the best results and healthiest outcome.

Never dye your hair within 7 days of relaxing it, no matter the circumstances. The longer you wait, the better for your hair’s health. This waiting period allows your hair and scalp to recover from the chemical stress of the relaxer.

Why the Waiting Period Matters

Relaxers leave your hair in a weakened state. The protein bonds have been broken, the cuticle layer is compromised, and your scalp may be sensitive or irritated. Adding dye too soon compounds the damage.

During the 7-14 day waiting period:

• Your hair begins to restore its natural moisture balance
• The cuticle layer starts to seal
• Your scalp heals from any irritation
• Residual chemicals from the relaxer are washed away

Wait for at Least One Shampoo Session

Along with waiting 7-14 days, you should also wait until after your first shampoo session following the relaxer. This ensures your scalp is clean and free from residual relaxer chemicals, which reduces the risk of irritation or adverse reactions when you apply dye.

Some professionals recommend waiting until after two shampoo sessions for extra safety, especially if you have a sensitive scalp.

Can You Ever Dye and Relax on the Same Day?

No. Dyeing and relaxing your hair on the same day is extremely risky and not recommended by any professional stylist. Doing both processes at once can cause:

• Severe hair breakage
• Chemical burns on the scalp
• Hair loss
• Uneven color results
• Permanent damage to hair structure

Always prioritize hair health over convenience or speed.

What Happens If You Dye Your Hair Too Soon After a Relaxer?

Dyeing your hair too soon after a relaxer can lead to serious hair and scalp damage. Here’s what can happen:

Excessive Breakage

Your hair is already weakened from the relaxer. Adding dye before it recovers can cause the hair shaft to snap or break off, especially at the line of demarcation (where new growth meets relaxed hair).

Chemical Overload

Combining two harsh chemicals in a short time period overwhelms the hair’s protein structure. This can lead to mushy, gummy hair that has lost its elasticity and strength.

Scalp Irritation and Burns

If your scalp hasn’t healed from the relaxer, dye chemicals can cause painful burning, redness, blistering, or even chemical burns.

Uneven or Unpredictable Color

Highly porous, damaged hair doesn’t absorb dye evenly. You may end up with patchy, blotchy, or entirely different colors than you intended.

Permanent Hair Damage

In severe cases, dyeing too soon can cause irreversible damage that requires cutting off significant lengths of hair.

Step-by-Step Guide: How to Dye Your Hair After a Relaxer

Follow these steps for the safest and most effective results when dyeing relaxed hair.

Step 1: Wait the Recommended Time

Wait at least 7-14 days after your relaxer treatment. During this time, focus on deep conditioning and moisturizing your hair.

Step 2: Assess Your Hair’s Health

Perform porosity and elasticity tests. If your hair seems weak or breaks easily, wait longer before dyeing.

Step 3: Do a Strand Test

Choose a small, hidden section of hair. Apply the dye according to instructions and check the processing time and color result. This helps you avoid surprises.

Step 4: Do a Patch Test

Test the dye on your skin 24-48 hours before full application to check for allergic reactions.

Step 5: Prepare Your Hair

• Shampoo your hair 1-2 days before dyeing (not the same day)
• Do not apply conditioner or heavy oils right before dyeing, as they can block dye penetration
• Detangle your hair gently

Step 6: Protect Your Scalp

Apply petroleum jelly or a scalp protectant along your hairline, ears, and neck to prevent staining and irritation.

Step 7: Mix the Dye Correctly

Follow the manufacturer’s instructions, but use a lower volume developer if your hair is relaxed (10 volume instead of 20 whenever possible).

Step 8: Apply the Dye

• Section your hair into four quadrants
• Apply dye starting from the ends and mid-lengths first
• Apply to roots last (they process faster due to scalp heat)
• Use a comb or brush to distribute evenly

Step 9: Monitor Processing Time

Set a timer based on your strand test results. Check your hair every 5-10 minutes. Relaxed hair typically processes in 20-30 minutes.

Step 10: Rinse Thoroughly

Rinse with cool or lukewarm water until the water runs clear. Avoid hot water, as it can strip color and cause dryness.

Step 11: Condition and Moisturize

Use the conditioner that comes with the dye kit or a deep conditioning treatment for color-treated hair. Leave it on for at least 5-10 minutes.

Step 12: Dry and Style Gently

Pat your hair dry with a microfiber towel. Avoid vigorous rubbing. Air-dry when possible, or use a blow dryer on a low heat setting.

Best Types of Hair Dye for Relaxed Hair

Not all dyes are suitable for relaxed hair. Here’s a breakdown of your options:

Semi-Permanent Dye

Aftercare: How to Maintain Dyed, Relaxed Hair

Once you’ve dyed your relaxed hair, proper maintenance is crucial to keep it healthy, vibrant, and strong.

Use Sulfate-Free Shampoo

Sulfates strip color and moisture from your hair. Switch to a gentle, sulfate-free shampoo designed for color-treated or chemically processed hair.

Deep Condition Weekly

Apply a deep conditioning mask or treatment once a week. Look for products with ingredients like shea butter, argan oil, coconut oil, or keratin.

Moisturize Daily

Use a leave-in conditioner, hair oil, or moisturizing cream daily to seal in hydration and prevent dryness and breakage.

Limit Heat Styling

Minimize the use of flat irons, curling irons, and blow dryers. When you do use heat, always apply a heat protectant spray first and use the lowest effective temperature.

Protect Hair at Night

Wrap your hair in a silk or satin scarf, or sleep on a silk or satin pillowcase. This reduces friction, prevents breakage, and helps retain moisture.

Trim Regularly

Get regular trims every 6-8 weeks to remove split ends and keep your hair looking healthy.

Avoid Over-Processing

Space out chemical treatments. Wait at least 8-12 weeks between relaxer touch-ups, and avoid dyeing your hair more than once every 4-6 weeks.

Use Protein Treatments

Once a month, use a protein treatment to strengthen hair and repair damage. Be careful not to overuse protein, as it can make hair brittle.

Protect from Sun and Chlorine

UV rays and chlorine can fade color and dry out hair. Wear a hat in the sun and a swim cap in the pool, or apply a UV-protectant hair product.

Common Mistakes to Avoid When Dyeing Relaxed Hair

Avoid these common pitfalls to protect your hair:

1. Dyeing Too Soon After Relaxing

This is the most common and damaging mistake. Always wait at least 7-14 days.

2. Using the Wrong Developer Volume

Using a developer that’s too strong will over-process your hair. Stick to 10 volume for relaxed hair whenever possible.

3. Skipping the Strand Test

Never skip the strand test. It saves you from disappointing or damaging results.

4. Leaving Dye On Too Long

Set a timer and check your hair regularly. Over-processing causes severe damage.

5. Not Moisturizing Enough

Dyed, relaxed hair needs constant moisture. Don’t neglect your conditioning routine.

6. Using Box Dye Without Adjusting

Box dyes are formulated for virgin hair. Adjust the developer volume and processing time for relaxed hair.

7. Ignoring Your Scalp

If your scalp is irritated, burning, or sore after a relaxer, wait longer before dyeing. Never dye on a damaged scalp.

Frequently Asked Questions

Can I relax my hair after dyeing it?

Yes, but you should wait at least 2-4 weeks after dyeing before relaxing. Relaxing after dyeing is generally safer than dyeing after relaxing, but still requires caution and proper timing.

Will dyeing my relaxed hair cause it to fall out?

If done correctly and after the proper waiting period, dyeing should not cause hair loss. However, dyeing too soon after relaxing or using harsh chemicals can lead to breakage and shedding.

Can I lighten my relaxed hair?

Lightening relaxed hair is riskier than darkening it because it requires stronger chemicals. If you must lighten, consult a professional stylist and use the lowest effective developer volume. Consider highlights or balayage instead of full bleaching.

How often can I dye relaxed hair?

Wait at least 4-6 weeks between dye applications. If you’re also getting relaxer touch-ups, plan your treatments so they’re spaced at least 2 weeks apart.

What should I do if my relaxed hair breaks after dyeing?

Stop all chemical treatments immediately. Focus on deep conditioning, protein treatments, and moisturizing. Trim damaged ends. If breakage is severe, consult a professional stylist or trichologist.

Can I use box dye on relaxed hair?

Yes, but adjust the developer volume and processing time. Box dyes are formulated for virgin hair, so they may be too strong for relaxed hair if used as directed.

Is it safe to dye relaxed hair during pregnancy?

Most experts consider hair dye safe during pregnancy, especially after the first trimester. However, pregnant women should use dyes in well-ventilated areas and consider ammonia-free options. Always consult your doctor first.

Can I swim after dyeing relaxed hair?

Wait at least 72 hours (3 days) after dyeing before swimming. Chlorine and saltwater can strip color and dry out your hair. Always wet your hair with clean water and apply a leave-in conditioner before swimming, and wear a swim cap when possible.

What’s the best way to cover gray hair on relaxed hair?

Permanent or demi-permanent dyes provide the best gray coverage. Choose a dye specifically formulated for gray coverage and textured hair. Apply the dye to gray areas first, as they often require longer processing time.

Can I use natural dyes like henna on relaxed hair?

Yes, but be cautious. Henna can react unpredictably with relaxed hair and may interfere with future chemical treatments. Do a strand test first and research thoroughly before applying henna to relaxed hair.

When You Should Skip Dyeing Your Relaxed Hair

There are times when dyeing is not a good idea, even if you’ve waited the recommended period:

• Your hair breaks easily or feels mushy
• You have visible scalp irritation, burns, or sores
• Your hair is extremely dry and brittle
• You’ve had multiple chemical treatments in the past few months
• Your hair has significant heat damage
• You’re experiencing unusual hair loss

In these cases, focus on hair recovery first. Use protein treatments, deep conditioners, and gentle care for at least 4-6 weeks before attempting to dye.

Final Thoughts

Dyeing your hair after a relaxer can give you a stunning, fresh look that boosts your confidence and lets you express your personal style. The key to success is patience, preparation, and proper care.

Always wait at least 7-14 days after relaxing before you dye. Choose products designed for relaxed or color-treated hair. Follow all safety guidelines, including strand tests and patch tests. And most importantly, prioritize the health of your hair above all else.

With the right approach, you can safely enjoy beautiful color on your relaxed hair without sacrificing its health and strength. Your hair is your crown—treat it with the care it deserves.

If you’re dealing with frizzy hair after chemical treatments, make sure to use proper conditioning products and follow a consistent moisture routine to keep your new style looking its best.

Once your color has settled and your hair is healthy, you might want to explore other styling options. Consider trying beach waves for a relaxed, textured look, or explore permanent hair straightening alternatives if you’re looking for different styling methods in the future.
