3 Easy Ways to Dye the Underneath of Your Hair

Dye the Underneath of Your Hair

You want a hair makeover without going for a full bleach or dye job? Dying the underneath of your hair is the perfect solution. This peek-a-boo color technique lets you add a subtle pop of color or create a bolder look, all while keeping the majority of your hair its natural color. Whether you’re a seasoned hair pro or a complete novice, dyeing the underneath of your hair is a relatively easy and affordable way to switch up your look.

First, you’ll need to gather your supplies. You’ll need a hair dye kit in the color of your choice, a developer, a mixing bowl and brush, and a pair of gloves. If you have long hair, you may also want to use a sectioning clip to keep the top layer of your hair out of the way. Once you have your supplies, you’re ready to get started.
Start by sectioning the top layer of your hair away from the bottom layer. Then, apply the hair dye to the underneath of your hair, starting at the roots and working your way down to the tips. Be sure to apply the dye evenly to avoid any streaks or patches. Once you have applied the dye to all of the underneath of your hair, cover it with a plastic cap and let it sit for the amount of time specified in the instructions.

After the processing time is up, rinse the dye out of your hair with cool water until the water runs clear. Then, shampoo and condition your hair as usual. To keep your new hair color looking its best, be sure to use color-safe shampoo and conditioner and avoid washing your hair too often. With proper care, your peek-a-boo hair color will last for several weeks.

Selecting the Right Dye

Choosing the right dye is crucial for achieving the desired results. Here are some factors to consider:

Permanent vs. Temporary Dye:

Permanent Dye	Temporary Dye
Lasts up to 8 weeks	Washes out in 1-2 shampoos
Changes the hair’s structure permanently	Does not alter the hair’s structure
Requires developer for activation	Ready-to-use, no developer needed

Color Choice:

Match the dye color to the desired result and your natural hair color. Consider the following:

For subtle highlights, choose a color 1-2 shades lighter than your base color.
For bold contrasts, select a color up to 4 shades darker or lighter.
If your hair is already dark, pre-lighten it before applying a lighter dye.
Use a vibrant dye for a dramatic effect, or a pastel shade for a soft glow.

Dye Formula:

Different dye formulas have specific properties. Choose based on your needs:

Dye Type	Properties
Cream Dye	Thick and easy to apply, provides long-lasting coverage
Gel Dye	Similar to cream dye, but more pigmented for bolder results
Foam Dye	Lightweight, mess-free, and suitable for fine or damaged hair
Powder Dye	Requires mixing with water or developer, offers maximum customization

Preparing Your Hair

Washing Your Hair

Ensure your hair is freshly washed and free from any styling products. Avoid using any rich conditioners since they can obstruct the color’s penetration into your hair strands.

Determine Your Bleaching Time

Decide how light you want the underneath of your hair to be. Refer to the provided table below to estimate the approximate bleaching time required for different hair colors:

Hair Color	Bleaching Time
Dark Brown	30-45 minutes
Medium Brown	20-30 minutes
Light Brown	15-20 minutes
Blonde	10-15 minutes

Section Your Hair

Part your hair into two sections, separating the top layer from the bottom layer. This will allow you to focus on dyeing only the underneath section.

Sectioning and Applying the Dye

### 1. Sectioning Your Hair

Before applying the dye, it’s crucial to divide your hair into manageable sections. This will ensure even application and prevent the dye from bleeding into unwanted areas. Start by parting your hair down the middle, then divide it horizontally into two layers. Clip up the top layer to keep it out of your way.

### 2. Applying the Dye to the Underneath Layer

Once your hair is sectioned, it’s time to apply the dye. Use a brush or comb to apply the dye evenly to the underneath layer of hair, avoiding the roots. Work in small sections, applying the dye from root to tip. Be careful not to overapply, as this can result in uneven results.

### 3. Processing Time

The processing time for hair dye varies depending on the brand and type of dye used. It’s important to follow the manufacturer’s instructions carefully. Generally, processing times range from 20 to 45 minutes. Check the dye label for specific guidance.

Dye Type	Processing Time
Permanent	30-45 minutes
Semi-Permanent	20-30 minutes
Temporary	10-20 minutes

During the processing time, keep the dye away from heat and sunlight. Cover the dyed area with plastic wrap or a towel to maintain moisture and prevent the dye from evaporating.

Developing Time

The developing time is crucial as it determines the intensity of the color. The recommended developing time varies depending on the brand and type of dye used. Follow the instructions provided by the manufacturer carefully to ensure optimal results.

Generally, the developing time ranges from 20 to 45 minutes. For subtle highlights, a shorter developing time of around 20-25 minutes is recommended. For more vibrant and intense color, a longer developing time of 30-45 minutes may be necessary.

It is essential to monitor the developing process closely. If the color is developing too quickly or too slowly, adjust the developing time accordingly. To test the color, gently wipe away a small section of the dye from the hair with a damp cloth. If the desired color is achieved, rinse the hair immediately to stop the developing process.

Developing Time	Color Intensity
20-25 minutes	Subtle highlights
30-45 minutes	Vibrant and intense color

Rinsing and Conditioning

Once you’ve let the hair dye set in, it’s time to rinse it out. Start by rinsing your hair with cool water until the water runs clear. This will help to remove any excess dye and prevent it from staining your skin or clothing.

After rinsing, condition your hair to help restore moisture and prevent damage. Apply a generous amount of conditioner to the ends of your hair, working your way up to the roots. Leave the conditioner in for a few minutes, then rinse it out with cool water.

Tips for Rinsing and Conditioning:

Here are a few tips to help you get the best results when rinsing and conditioning your hair after dyeing:

Use cool water to rinse your hair. Hot water can open up the hair cuticles, allowing the dye to escape.
Rinse your hair until the water runs clear. This will help to remove any excess dye and prevent it from staining your skin or clothing.
Use a sulfate-free shampoo and conditioner. Sulfates are harsh detergents that can strip your hair of its natural oils, making it dry and brittle.
Apply conditioner to the ends of your hair first. The ends of your hair are the most damaged and need the most moisture.
Leave the conditioner in for a few minutes before rinsing it out. This will give the conditioner time to penetrate the hair shaft and do its job.

Step	Instructions
1	Rinse your hair with cool water until the water runs clear.
2	Apply a generous amount of conditioner to the ends of your hair, working your way up to the roots.
3	Leave the conditioner in for a few minutes, then rinse it out with cool water.

Post-Dye Care

1. Wash your hair with sulfate-free shampoo.

Sulfates are harsh detergents that can strip your hair of its natural oils, so it’s important to use a gentle shampoo that will not damage your hair.

2. Condition your hair regularly.

Conditioning your hair will help to keep it soft and manageable. You should condition your hair at least once a week, and more often if your hair is dry or damaged.

3. Avoid heat styling.

Heat styling can damage your hair, especially if it is dyed. Air dry your hair whenever possible, and use a heat protectant spray if you must use styling tools.

4. Protect your hair from the sun.

The sun can damage your hair and cause it to fade. Wear a hat or scarf when you’re outdoors, and use a UV protectant spray on your hair.

5. Touch up your roots regularly.

As your hair grows, your roots will start to show. Touch up your roots every 4-6 weeks to keep your hair looking fresh.

6. Get regular trims.

Split ends can make your hair look dry and damaged. Get regular trims to remove split ends and keep your hair looking healthy.

Frequency	Benefits
Once a week	Moisturizes hair Detangles hair Prevents breakage
Every 4-6 weeks	Covers roots Keeps hair looking fresh Prevents hair from becoming dull
Every 6-8 weeks	Removes split ends Promotes hair growth Makes hair look healthy

Materials You’ll Need:

Here’s a list of essential materials:

Hair dye in your desired color
Developer solution
Mixing bowl and brush
Gloves
Petroleum jelly or oil

Touch-Up Techniques

Section 7: Dyeing the Underneath of Long or Thick Hair

If you have long or thick hair, it’s crucial to section it properly to ensure even coverage. Divide your hair into four quadrants: front, back, left, and right. Secure the top three quadrants with hair clips or hair ties. Apply petroleum jelly or oil to your hairline and ears to prevent dye from staining them.

Starting with the back section, use a tail comb to create thin, horizontal sections. Apply the dye with the brush, starting at the roots. Pull the sections taut to minimize bleeding onto the top hair. Repeat this process for the left, right, and front sections.


Step 1: Section hair	Divide hair into 4 quadrants
Step 2: Create thin, horizontal sections	Use a tail comb to create thin sections
Step 3: Apply dye	Start at the roots and pull sections taut

Allow the dye to process according to the manufacturer’s instructions, usually around 30-45 minutes. Rinse thoroughly with cool water and shampoo and condition as usual.

Blending the Underneath Dye

Once you’ve applied the dye to the underneath layer of your hair, you’ll need to blend it with the rest of your hair. This will help to create a natural-looking effect.
There are a few different ways to blend the dye, but one of the easiest methods is to use a blending brush. A blending brush is a small, round brush with soft bristles. To use a blending brush, simply dip it into the dye and then brush it through the hair in small, circular motions.
You can also blend the dye using your fingers. To do this, simply apply a small amount of dye to your fingers and then massage it into the hair. Be sure to blend the dye well so that there are no harsh lines.
Once you’ve blended the dye, you can style your hair as usual. You can wear it down, up, or in a ponytail. The dye will be less noticeable if you wear your hair down, but it will still add a subtle pop of color.
If you’re not sure how to blend the dye, you can always ask a professional hairstylist for help.
Here are some additional tips for blending the underneath dye:
Start by applying the dye to the roots of your hair. This will help to create a more natural look.
Use a small amount of dye and build it up gradually. This will help to prevent the dye from looking too harsh.
Blend the dye well so that there are no harsh lines.
Once you’ve blended the dye, you can style your hair as usual.

Troubleshooting Dye Issues

Uneven Dye Uptake

If the dye is not taken up evenly, it could be due to several factors:

Chemical build-up from previous styling products
Hair that is not clean before dyeing
Bleaching the hair too quickly

To avoid this, thoroughly wash the hair before dyeing, use a clarifying shampoo, and follow the timing instructions for bleaching and dyeing carefully.

Dye Fading Too Quickly

There are a few reasons why dye may fade quickly:

Using dye that is not designed for your hair type
Washing the hair too frequently
Using hot water to wash the hair
Exposure to sunlight

To preserve the color, choose a dye specifically formulated for your hair type, avoid over-washing, use cold water to rinse the hair, and protect it from sunlight with a hat or scarf.

Allergic Reactions

Although rare, allergic reactions to hair dye can occur. Symptoms may include:

Symptom	Severity
Skin irritation	Mild to moderate
Hives	Moderate to severe
Swelling	Moderate to severe
Difficulty breathing	Severe

If you experience any allergic reactions, seek medical attention immediately.

Safety Precautions

To ensure a safe and successful hair dyeing experience, follow these important precautions:

1. Skin Test

Conduct a patch test 24 hours before application to rule out any allergic reactions. Apply a small amount of dye to an inconspicuous area of skin and observe for any irritation or redness.

2. Protect Clothing and Hairline

Wear an old shirt or use a towel to cover your clothing. Apply a petroleum jelly or Vaseline along your hairline to prevent stains.

3. Proper Ventilation

Ventilate the area by opening windows or using a fan. Avoid confined spaces with limited airflow.

4. Wear Gloves

Use rubber or latex gloves to protect your hands from the dye.

5. Use Mild Shampoo

Before dyeing, wash your hair with a mild shampoo to remove any dirt or styling products.

6. Detangle Hair

Brush your hair thoroughly to remove any tangles or knots.

7. Bleaching

If your hair is dark and you want to achieve a lighter color, you may need to bleach it first. Follow the instructions carefully to prevent damage.

8. Avoid Over-Processing

Do not leave the dye on for longer than the recommended time. Over-processing can lead to hair damage and breakage.

9. Rinse Thoroughly

Rinse your hair thoroughly with cool water after dyeing. You may need to use a clarifying shampoo to remove any remaining dye.

10. Seek Professional Help

If you have any concerns or doubts, seek professional advice from a hair stylist or colorist. They can assess your hair condition and provide guidance on the best dyeing methods.
