However, dyeing the underneath of your hair can be a little tricky. If you don’t do it right, you could end up with a blotchy, uneven mess. This article will provide you with a step-by-step guide on how to dye the underneath of your hair. I will also provide you with some tips and tricks to help you get the best results. So, what are you waiting for? Let’s get started!

Before you start dyeing the underneath of your hair, you need to gather your supplies. You will need:

– Hair dye in the color of your choice
– Developer
– Mixing bowl
– Applicator brush
– Gloves
– A towel
– A comb
– A blow dryer
– Optional: Toner

Gather the Necessary Materials

To dye the underneath layer of your hair, you’ll need a few essential materials. Here’s a detailed list of everything you’ll require:

Hair Dye

Choosing the right hair dye is crucial. Opt for a semi-permanent or permanent dye specifically designed for underneath hair. Semi-permanent dyes last for several weeks to months and fade gradually, while permanent dyes provide long-lasting results. Consider factors like your natural hair color, desired shade, and the amount of gray coverage you need when selecting the dye.

Dye Applicator

A dye applicator is indispensable for applying the color evenly. Choose a brush or comb applicator with fine bristles that can precisely target the underneath layer of hair. A bowl for mixing the dye is also essential.

Developer

The developer is mixed with the hair dye to activate it. Follow the instructions on the dye packaging to determine the correct proportions of dye and developer. Typically, a 20-volume developer is suitable for most shades.

Gloves

Wear protective gloves throughout the dyeing process to prevent staining your hands.

Vaseline or Petroleum Jelly

Applying a thin layer of Vaseline or petroleum jelly around your hairline and ears will protect your skin from any dye that may transfer.

Towels

Cover your shoulders and work area with towels to absorb any spills or drips.

Mixing Utensils

Use a non-metallic bowl and spoon for mixing the dye and developer.

Tail Comb

A tail comb will help you separate the top layer of hair from the underneath layer.

Cling Wrap or Plastic Cap

After applying the dye, cover your hair with cling wrap or a plastic cap to trap heat and promote color absorption.

Shampoo and Conditioner

You’ll need shampoo and conditioner to wash your hair after dyeing.

Section and Bleach the Hair

Bleach Hair

Here are the steps to bleach the hair:

  1. Divide the bottom layer of hair into three to four sections.
  2. Do not wash hair before applying the bleach.
  3. Put on the gloves.
  4. Mix according to the manufacturer’s guidelines.
  5. Using an application brush, paint bleach onto the bottom section of the hair, about a quarter-inch to ½ inch from the roots.
  6. Apply more bleach to the hair with your non-gloved hand.
  7. Wait 20 minutes and then check hair every 10 minutes.
  8. Rinse when hair reaches the desired level of lightness.
  9. Let hair dry completely.

Choose Your Dye Color

The first step in dyeing the underneath of your hair is selecting the right color. Consider the following factors:

Your Natural Hair Color

Choose a dye color that complements your natural hair color. For example, if you have dark hair, you may opt for a vibrant shade of red or purple to create a striking contrast. Conversely, if you have light hair, a subtle shade of pastel pink or blue can add a touch of whimsy.

Desired Effect

Decide the desired effect you want to achieve. Do you want a bold, all-over color or a more subtle peek-a-boo effect? If you prefer a bolder look, choose a dye that is several shades darker or lighter than your natural hair color. For a more subtle effect, opt for a dye that is only a few shades different.

Your Skin Tone

Consider your skin tone when selecting a dye color. Warm skin tones look best with warm colors, such as red, orange, and yellow. Cool skin tones look best with cool colors, such as blue, green, and purple. If you are unsure of your skin tone, you can do a color test by placing a piece of white paper next to your face. If your skin looks pink or peachy, you have a warm skin tone. If it looks yellowish or olive, you have a cool skin tone.

Here is a table summarizing the recommended dye colors based on skin tone and desired effect:

Skin ToneDesired EffectRecommended Dye Colors
WarmBoldVibrant shades of red, orange, yellow
CoolBoldDeep shades of blue, green, purple
WarmSubtlePastel shades of pink, peach, coral
CoolSubtlePastel shades of blue, lavender, mint

Apply the Dye

Now it’s time to apply the dye. Follow these steps to ensure a vibrant and even color:

4. Section Your Hair for Even Application

Sectioning your hair into smaller parts allows you to apply the dye more evenly and thoroughly. Part your hair into four quadrants: two sections in the front and two in the back. Use hair clips or bobby pins to keep each section separated.

Within each quadrant, further divide your hair into smaller subsections. This will help you apply the dye to all the hidden layers and achieve a consistent color.

Here’s a table to help visualize the sectioning process:

FrontBack
  • Section 1: Left front
  • Section 2: Right front
  • Section 3: Left back
  • Section 4: Right back

Within each section, create smaller subsections for even application.

Process

Start by preparing your hair and the dye as per the manufacturer’s instructions. Section the hair into smaller parts to make it easier to dye. Apply the dye to the underside of the hair, using a brush or sponge. Allow the dye to process for the recommended time, usually around 20-30 minutes.

Rinse

Once the processing time is complete, rinse out the dye thoroughly with lukewarm water until the water runs clear. Shampoo and condition your hair to remove any remaining dye and restore moisture.

Additional Tips

Here are some additional tips for dyeing the underside of your hair:

  • Use a light-colored dye if you want a subtle effect or a darker dye if you want a more dramatic look.
  • Test the dye on a small strand of hair first to ensure you like the color.
  • Apply a thick layer of dye to the underside of the hair to achieve even coverage.

Recommendations for Specific Hair Types

The type of hair you have will affect how well the dye takes and how long it lasts. Here are some recommendations for specific hair types:

Hair TypeRecommendations
Virgin hairUse a light-colored dye and leave it on for a shorter processing time.
Chemically treated hairUse a demi-permanent dye and leave it on for the recommended processing time.
Bleached hairUse a permanent dye and leave it on for the maximum processing time.

Tone the Hair

Before applying the desired color to the underneath section of your hair, it’s crucial to consider its current tone and condition.

Cleanse and Condition

Thoroughly wash your hair with a clarifying shampoo to remove any product buildup or dirt. Applying color to clean hair will ensure even absorption and prevent color buildup.

Identify Hair Tone

Determine the existing tone of your hair using a hair color chart. This will help you choose the best toning agent for your desired result.

Pre-Toning

If the underneath section of your hair is significantly lighter or darker than your natural color, pre-toning may be necessary. This step involves applying a demi-permanent or semi-permanent color to adjust the tone to a suitable base.

Demi-Permanent Color

Demi-permanent color does not contain ammonia and lasts for 12-24 washes, gradually fading over time. It’s ideal for subtle adjustments and adding warmth or coolness to the hair.

Semi-Permanent Color

Semi-permanent color is deposited only on the hair shaft and can last for 4-8 washes. It provides a vibrant tint and is suitable for temporary color changes or adding bright tones.

Over-washing can strip your hair of its natural oils, which can lead to dryness and fading.

Use Color-Safe Shampoo and Conditioner

These products are formulated to be gentle on colored hair and help preserve its color.

Protect Hair from the Sun

UV rays can damage your hair and cause it to fade. Wear a hat or scarf when exposed to the sun for extended periods.

Avoid Heat Styling

Heat styling tools can damage your hair and cause color to fade. If you must use heat tools, use them on a low setting and apply a heat protectant spray to your hair.

Get Regular Trims

Regular trims will remove split ends and help keep your hair looking healthy and vibrant.

Use Hair Masks

Hair masks can help to deeply condition and hydrate your hair, which can help to prevent fading.

Avoid Chlorine and Salt Water

Chlorine and salt water can cause your hair to become dry and brittle, which can lead to fading.

Tips for Vibrant Color

Achieving vibrant, long-lasting color underneath your hair requires careful preparation and proper maintenance. Here are some tips to ensure your new hue stays vibrant and eye-catching:

1. Use High-Quality Dye

Invest in a high-quality hair dye designed specifically for underneath hair. These dyes typically contain stronger pigments and are formulated to last longer.

2. Clean Hair Thoroughly

Start with clean hair to ensure the dye adheres properly. Wash your hair with a clarifying shampoo to remove any dirt or product buildup.

3. Section Your Hair

Section your hair into manageable sections to make the dyeing process easier. This will help prevent uneven application.

4. Apply the Dye Evenly

Apply the dye evenly throughout the underneath hair, ensuring that all strands are well-covered. Use a brush or comb for even distribution.

5. Process the Dye According to Instructions

Follow the processing instructions on the dye package carefully. The processing time will vary depending on the dye and your hair type.

6. Rinse and Condition

Once the dye has processed, rinse your hair thoroughly with cool water until the water runs clear. Apply a color-safe conditioner to help seal and protect the color.

7. Touch Up Regularly

As your hair grows, the underneath color will start to fade. Touch up your roots regularly to maintain the vibrant hue.

8. Avoid Harsh Chemicals

Avoid using harsh shampoos, hairsprays, or heat styling tools, as these can strip away color and damage your hair. Use gentle, color-safe products and always protect your hair from heat when styling.

Troubleshooting Common Problems

1. The color didn’t turn out as expected:
Check if the dye was applied evenly, waited for the correct amount of time, and mixed according to the instructions. If the color is too light, you can try dyeing it again with a darker shade. If it’s too dark, use a color remover or bleach to lighten it.

2. The hair is damaged:
Use a deep conditioner and avoid heat styling to repair the hair. If the damage is severe, you may need to cut off the damaged hair.

3. The dye stained my skin:
Use a makeup remover to remove any dye stains from the skin. If the stain is stubborn, try rubbing alcohol or baby wipes.

4. The dye is bleeding onto my clothes:
Wash your clothes in cold water and use a color-safe bleach. If the bleeding persists, you may need to use a dye-setting spray or vinegar rinse.

5. The dye caused an allergic reaction:
Stop using the dye and seek medical attention if you experience any redness, itching, or swelling.

6. The dye has a strong odor:
Ventilate the area where you are dyeing your hair and avoid inhaling the fumes. If the odor is too strong, you can use a hair dryer or fan to help dissipate it.

7. The dye is too thick or thin:
Add water or more dye to achieve the desired consistency.

8. The dye brush is difficult to use:
Use a brush with soft bristles and a fine tip. If the brush is too stiff, it can damage the hair.

9. The hair feels sticky after dyeing:
Use a clarifying shampoo and conditioner to remove any residue from the dye. You can also try using a leave-in conditioner or serum to restore moisture to the hair.
