Help! My Highlights Are Too Dark: A Comprehensive Guide to Lightening Overly Dark Highlights

Getting highlights is a fantastic way to add dimension and brightness to your hair. However, sometimes things don’t go as planned, and you might end up with highlights that are much darker than you envisioned. Whether it’s a salon mishap or a DIY experiment gone wrong, overly dark highlights can be frustrating and disheartening. But don’t panic! You’re not stuck with them. This comprehensive guide will walk you through various methods to lighten those overly dark highlights, helping you achieve the look you truly desire. We’ll explore everything from gentle, natural approaches to more potent techniques, along with crucial tips to protect the health and integrity of your hair during the process.

Understanding Why Highlights Go Dark

Before diving into solutions, let’s understand why highlights sometimes turn out darker than expected. Several factors contribute to this issue, and knowing them can help you avoid similar situations in the future:

• Incorrect Bleach/Developer Ratio: Using the wrong ratio of bleach to developer is a common culprit. Too much developer or a developer that’s too high in volume can cause the bleach to work too quickly and unevenly, leading to a darker, more brassy tone.
• Inadequate Application: If the bleach is not applied evenly or in the correct sections, some areas might end up darker than others. This often happens when the bleach is left on too long in some places and not long enough in others.
• Hair Color History: Previous hair coloring, especially box dye, can create barriers that interfere with bleach. These barriers can cause bleach to process unevenly and appear darker in some areas. Also, dyes often contain metallic salts that can react unpredictably with bleach.
• Toner Application: While toners are meant to neutralize unwanted undertones, using a toner that’s too dark or left on for too long can darken the overall look of the highlights. Sometimes, a toner can make the highlights appear much deeper than intended.
• Natural Hair Pigment: Darker natural hair color often requires more lift to achieve lighter highlights. If not enough lift is achieved, the results can appear muddy and darker than expected.
• Overlapping Bleach: When touch-ups are done and bleach overlaps onto previously lightened sections, it can cause these areas to become darker due to increased processing time and potential damage.

Assessing Your Hair Before Lightening

Before embarking on any lightening process, it’s crucial to assess your hair’s condition. This will help you choose the right method and minimize potential damage. Here’s what to consider:

• Hair Porosity: Porous hair tends to absorb color quickly, making it prone to damage and brassiness. If your hair is porous (it feels rough, dries quickly, and absorbs products fast), opt for gentle lightening methods and shorter processing times.
• Hair Elasticity: Healthy hair has good elasticity. If your hair stretches and returns to its original shape when wet, it’s in good condition. If it breaks or feels like chewing gum when wet, it’s likely damaged and needs extra care.
• Hair Density: If you have thick hair, you might need more product to ensure even coverage. Thin hair may be more susceptible to damage, so using a gentler method is important.
• Recent Chemical Treatments: Have you recently permed, relaxed, or colored your hair? If so, proceed with caution as your hair might already be fragile. It’s best to wait before attempting to lighten again.
• Scalp Condition: Make sure your scalp is healthy and free of any irritations before using any chemicals. If you have a sensitive scalp, it’s crucial to test any new product on a small area first.

Gentle Lightening Methods: When Less is More

If your highlights are only slightly too dark or if your hair is delicate, it’s wise to start with gentler methods. These techniques often require more patience and several applications but minimize damage. Here are some options:

1. Anti-Dandruff Shampoo

This might seem counterintuitive, but anti-dandruff shampoos, particularly those containing sulfates, can help to fade color over time. Sulfates are powerful cleansers that can lift color molecules from the hair. Here’s how to use it:

1. Choose the Right Shampoo: Opt for a clarifying anti-dandruff shampoo with sulfates. Avoid color-safe formulas as they are designed to preserve color.
2. Wet Your Hair: Thoroughly wet your hair with warm water.
3. Apply Shampoo: Apply a generous amount of the shampoo to your hair, focusing on the highlighted areas.
4. Massage and Lather: Gently massage the shampoo into your hair and scalp, working it into a rich lather.
5. Leave it On: Let the shampoo sit in your hair for 5-10 minutes. This will give it time to lift the color.
6. Rinse Thoroughly: Rinse your hair thoroughly with warm water.
7. Condition: Apply a hydrating conditioner to your hair. This will replenish moisture lost during the shampooing process.
8. Repeat: Repeat this process 1-2 times a week until you achieve the desired lightness.

Caution: This method can be drying, so be sure to use a deep conditioner regularly and limit usage to a couple of times a week.

2. Honey and Conditioner Mask

Honey contains natural bleaching agents and when combined with conditioner, can provide a gentle and hydrating way to lift color. Here’s how to make and use this mask:

1. Gather Ingredients: You will need 2-3 tablespoons of raw honey (Manuka honey is preferred but any raw honey will do) and about 4 tablespoons of your regular conditioner.
2. Mix Ingredients: In a small bowl, combine the honey and conditioner. Mix well until you have a smooth and consistent paste.
3. Apply to Hair: Apply the mixture to your damp or dry hair, focusing on the highlighted areas. Ensure the highlights are fully covered.
4. Cover Hair: Place a shower cap or plastic wrap over your hair to keep it moist and warm, which helps the mixture penetrate better.
5. Leave It On: Let the mask sit in your hair for at least 2-3 hours, or even overnight for a more noticeable effect.
6. Rinse: Thoroughly rinse your hair with warm water until the mask is completely washed out.
7. Shampoo (Optional): You can wash your hair with a gentle, sulfate-free shampoo if desired, but it’s not always necessary.
8. Condition: Apply a hydrating conditioner to replenish any lost moisture.
9. Repeat: You can repeat this mask 1-2 times a week until you achieve your desired result.

Caution: Honey can be sticky, so be careful when applying it. Also, it’s important to patch test this mask on a small area of your skin to make sure you’re not allergic to honey before applying it to your hair.

3. Vitamin C Treatment

Vitamin C is known for its brightening properties and can gently lift color. Here’s how to use it:

1. Gather Ingredients: You will need about 5-10 vitamin C tablets and about 2 tablespoons of a gentle, sulfate-free shampoo.
2. Crush Tablets: Crush the vitamin C tablets into a fine powder using a mortar and pestle or the back of a spoon.
3. Mix with Shampoo: In a small bowl, mix the powdered vitamin C with your shampoo until you have a smooth paste.
4. Apply to Hair: Apply the mixture to your damp hair, focusing on the areas with dark highlights.
5. Massage and Lather: Gently massage the mixture into your hair and scalp for even coverage.
6. Leave It On: Let it sit for about 20-30 minutes.
7. Rinse Thoroughly: Rinse your hair with cool water until the mixture is completely washed out.
8. Condition: Apply a moisturizing conditioner to your hair to combat any dryness.
9. Repeat: You can repeat this process once or twice a week for a gradual lightening effect.

Caution: Vitamin C can be drying for some, so be sure to use a conditioner or hair mask afterwards to replenish moisture.

4. Sun Exposure (with Caution)

The sun’s natural rays can help to lighten hair color, but this method needs to be approached with caution. Here’s how to use sun exposure safely:

1. Choose the Right Time: The best time to expose your hair to the sun is during the early morning or late afternoon when the sun’s rays are less intense. Avoid midday sun.
2. Apply a Protective Product: Before going out in the sun, apply a leave-in conditioner or a hair product containing UV protection to prevent damage and dryness.
3. Limit Exposure Time: Spend no more than 20-30 minutes in direct sunlight at a time. Overexposure can lead to dryness and damage.
4. Moisturize: After sun exposure, use a hydrating hair mask or conditioner to keep your hair moisturized.
5. Repeat: You can do this several times a week while monitoring your hair’s condition and color.

Caution: Overexposure to the sun can cause significant damage. Always use a protective product and be sure to limit time spent in the sun.

More Potent Lightening Methods: Proceed with Care

If gentle methods haven’t provided the desired results, you might consider more potent solutions. These methods are more effective at lifting color but also carry a higher risk of damage. It’s best to approach them with caution and ideally seek professional help if you’re not confident.

1. Bleach Wash (also known as a Soap Cap)

A bleach wash is a gentler alternative to a full bleach application. It’s less damaging because the bleach is diluted with shampoo. Here’s how to do it:

1. Gather Ingredients: You will need bleach powder, a low-volume developer (10 or 20 volume), and a sulfate-free shampoo. Make sure you have gloves and a mixing bowl as well.
2. Prepare Mixture: In a non-metallic mixing bowl, mix equal parts of bleach powder, developer, and shampoo. For example, you can start with 1 tablespoon of each.
3. Apply to Hair: Apply the mixture to your damp hair, focusing on the areas with dark highlights. Ensure even coverage.
4. Massage Gently: Gently massage the mixture into the highlights to ensure they’re well saturated.
5. Check Regularly: Keep a close eye on your hair, checking every 5-10 minutes. The goal is to lift the color just slightly without over-processing.
6. Rinse Thoroughly: Once you reach the desired lightness or after a maximum of 20 minutes, rinse your hair thoroughly with cool water.
7. Shampoo and Condition: Wash your hair with a gentle, sulfate-free shampoo and follow with a moisturizing conditioner.
8. Deep Condition: Apply a deep conditioning mask to replenish moisture.

Caution: This method can still cause damage. If you’re unsure, it’s best to get professional advice before attempting it.

2. Color Remover

Color removers are designed to remove artificial hair color without using bleach. However, they can be drying and might not lift color from very dark highlights completely. Here’s how to use them:

1. Choose the Right Product: Select a color remover specifically for hair that has been colored. Follow the instructions on the box carefully.
2. Perform a Strand Test: Before applying the remover to your entire head, do a strand test to see how your hair reacts and ensure it’s suitable.
3. Mix the Remover: Mix the remover according to the package instructions.
4. Apply to Hair: Apply the remover evenly to your damp hair, focusing on the dark highlights.
5. Cover Hair: Cover your hair with a plastic cap or wrap.
6. Follow Instructions: Leave the remover on for the recommended time as per the product instructions.
7. Rinse Thoroughly: Rinse your hair thoroughly with warm water.
8. Shampoo and Condition: Wash your hair with a sulfate-free shampoo and follow with a deep conditioner.

Caution: Color removers can be drying, so it’s essential to use a deep conditioner after treatment. Also, some removers can reactivate the dye, so be careful.

3. Low-Volume Bleach Application (for experienced users)

This method should only be attempted if you have experience with bleaching hair. If done incorrectly, it can cause severe damage. Here’s how to use low-volume bleach safely:

1. Gather Supplies: You’ll need bleach powder, 10 or 20 volume developer, a mixing bowl, gloves, and a tinting brush.
2. Prepare the Mixture: In the mixing bowl, combine the bleach powder and developer in a 1:2 ratio (for example, 1 scoop of bleach powder to 2 scoops of developer). Mix well.
3. Apply to Highlights: Apply the mixture carefully to the dark highlights only, avoiding the scalp and previously lightened areas.
4. Check Regularly: Check your hair every 5-10 minutes to monitor the lightening process.
5. Rinse Thoroughly: Once you’ve reached your desired shade, rinse your hair thoroughly with cool water.
6. Shampoo and Condition: Use a color-safe, sulfate-free shampoo and follow with a deep conditioner or hair mask.
7. Apply a Toner: After bleaching, a toner might be needed to neutralize unwanted yellow or orange tones.

Caution: This method carries a high risk of damage. If you’re not experienced with bleaching, consult a professional stylist.

Toning Your Highlights After Lightening

After lightening your highlights, you might notice that they appear brassy or yellow. This is normal. Toning is crucial to achieve the desired cool or neutral tone. Here’s how to tone your highlights:

• Choose the Right Toner: Select a toner that counteracts the unwanted undertones. For yellow tones, choose a purple or violet toner. For orange tones, use a blue toner.
• Follow Instructions: Carefully follow the instructions on the toner product. Most toners are mixed with a low-volume developer.
• Apply Evenly: Apply the toner evenly to your damp hair, focusing on the highlighted areas.
• Leave it On: Leave the toner on for the time specified in the instructions.
• Rinse Thoroughly: Rinse your hair thoroughly with cool water.
• Condition: Use a hydrating conditioner to lock in the color and moisture.

Post-Lightening Care: Maintaining Healthy Hair

Lightening, no matter the method, can be damaging to your hair. Proper post-lightening care is crucial to keeping your hair healthy and vibrant. Here are some tips:

• Hydrate Regularly: Use a deep conditioner or hair mask at least once a week to replenish moisture.
• Use Sulfate-Free Products: Sulfate shampoos can strip hair of its natural oils, leading to dryness and color fading. Opt for sulfate-free alternatives.
• Avoid Heat Styling: Minimize heat styling as much as possible. When you do use heat, apply a heat protectant spray.
• Trim Regularly: Regular trims help to get rid of split ends, preventing them from travelling up the hair shaft.
• Limit Washing: Try to wash your hair no more than 2-3 times a week to avoid stripping it of its natural oils.
• Protect from Sun: If you’ll be spending time in the sun, use a leave-in conditioner with UV protection.
• Use Hair Oils: Apply hair oils to the ends of your hair to seal in moisture and prevent dryness.

When to Seek Professional Help

While these methods can help you lighten overly dark highlights at home, sometimes it’s best to seek professional help. Consider consulting a stylist if:

• Your hair is severely damaged: If your hair is brittle, dry, or breaking, it’s best to leave lightening to a professional who can assess your hair’s condition.
• You’re unsure of the process: If you’re not confident about your abilities or don’t want to risk damaging your hair, a professional stylist can ensure safe and effective lightening.
• You’ve had previous negative experiences: If you’ve had bad experiences with DIY hair coloring in the past, it’s best to leave it to a professional this time around.
• You want a specific color: If you’re aiming for a very specific shade of highlights, a professional can use their expertise and experience to create a customized look.
• Your hair is very dark: Lifting very dark hair to a much lighter shade can be tricky and may require professional expertise.

Conclusion

Dealing with overly dark highlights can be frustrating, but it’s certainly not a permanent situation. By understanding why highlights go dark and choosing the appropriate lightening method, you can gradually achieve the beautiful, bright highlights you envision. Remember to prioritize the health of your hair during the process and don’t hesitate to seek professional help if needed. With patience, care, and the right techniques, you’ll be able to correct your dark highlights and enjoy your revitalized hair.
