From Blonde to Brunette: A Comprehensive Guide to Dyeing Bleached Hair Back to Your Natural Color

So, you’ve taken the plunge and bleached your hair, enjoyed the blonde life for a while, but now you’re ready to return to your roots – literally! Dyeing bleached hair back to its natural color can seem daunting, but with the right preparation, products, and techniques, you can achieve a beautiful, natural-looking result. This comprehensive guide will walk you through everything you need to know, from understanding the science behind hair color to step-by-step instructions and tips for maintaining your new hue.

Why Dyeing Bleached Hair Back to Natural Color is Tricky

Before diving into the process, it’s crucial to understand why coloring bleached hair is different from coloring virgin hair. Bleaching strips your hair of its natural pigment, leaving it porous and susceptible to absorbing color unevenly. Here’s a breakdown:

* **Porosity:** Bleached hair has a raised cuticle layer, making it more porous. This means it absorbs color quickly, but also loses it just as fast. Think of it like a sponge; it soaks up water (or dye) easily but also dries out quickly.
* **Missing Underlying Pigments:** Natural hair color isn’t just one shade. It’s a combination of underlying pigments (red, orange, yellow) that create the overall tone. Bleaching removes these pigments, leaving a blank canvas. When you apply a single color, it can appear flat and unnatural because it lacks the depth and dimension of natural hair.
* **Green Tones:** Sometimes, when you apply a brown dye directly to bleached hair, it can turn green. This is because bleached hair often has a yellow undertone, and when combined with the blue tones in many brown dyes, it can create a greenish cast. This is especially common with ash-toned browns.

Preparing Your Hair for the Dyeing Process

Proper preparation is key to a successful color transformation. Here’s what you need to do:

* **Assess Your Hair’s Condition:** Bleaching can be damaging, so it’s important to assess the health of your hair. If your hair is extremely dry, brittle, or prone to breakage, focus on deep conditioning treatments for a few weeks before attempting to color it. A protein treatment can also help strengthen your hair.
* **Deep Conditioning Treatments:** Use deep conditioning masks or treatments at least once a week for a few weeks before dyeing. Look for products that contain ingredients like shea butter, coconut oil, argan oil, or keratin. These will help to hydrate and nourish your hair, making it more receptive to color.
* **Protein Treatments (Use with Caution):** Protein treatments can help strengthen damaged hair, but overuse can lead to stiffness and breakage. Use protein treatments sparingly and follow the instructions carefully. If your hair feels dry or brittle after a protein treatment, follow up with a moisturizing treatment.
* **Avoid Heat Styling:** Minimize heat styling (blow dryers, straighteners, curling irons) in the weeks leading up to your dyeing appointment. Heat can further damage already weakened hair.
* **Clarifying Shampoo:** A day or two before dyeing, use a clarifying shampoo to remove any buildup of product or minerals from your hair. This will help the dye penetrate more evenly.
* **Skip Washing Your Hair the Day Of:** Don’t wash your hair the day you plan to dye it. The natural oils on your scalp will help protect it from irritation and the dye will adhere better.
* **Strand Test is Crucial:** Always, always, always do a strand test before applying the dye to your entire head. This will allow you to see how the color will look on your hair and whether you need to adjust the formula or processing time. Choose a hidden section of hair, like underneath a layer at the nape of your neck, and apply the dye according to the instructions. This small step can save you from a major color disaster.

Choosing the Right Products

Selecting the right products is just as important as the preparation. Here’s what to look for:

* **Demi-Permanent vs. Permanent Hair Dye:** For dyeing bleached hair back to its natural color, demi-permanent hair dye is generally recommended. Demi-permanent dye deposits color without lifting the hair’s natural pigment, making it less damaging and more likely to fade gracefully. Permanent dye, on the other hand, opens the hair cuticle and deposits color deep within the hair shaft, which can be more damaging and harder to remove if you change your mind. However, if you are covering grey, or want the color to last longer, permanent might be your only option.
* **Choosing the Right Shade:** This is where things can get tricky. Don’t just pick a box that says “natural brown” or “dark blonde.” You need to consider the underlying tones in your hair and the color you want to achieve. A good rule of thumb is to go one or two shades lighter than your target color, as bleached hair tends to absorb color more intensely. It’s also helpful to look at the color wheel and understand which tones will neutralize any unwanted hues in your bleached hair.
* **Counteracting Green Tones:** If you’re concerned about your hair turning green, choose a dye with warm undertones, such as red or gold. These will help to neutralize any greenness and create a more balanced, natural-looking color. Look for dyes with names like “golden brown,” “red-brown,” or “chestnut brown.”
* **Fillers:** If your hair is very light blonde, you may need to use a filler before applying your target color. A filler is a dye that contains the missing underlying pigments (red, orange, yellow) that were removed during bleaching. This will help to create a more even and natural-looking base for your final color. A good strategy is to use a shade or two lighter and redder than your desired color, then go over with the target shade. Alternatively, try using a protein filler.
* **High-Quality Developer (if using permanent dye):** If you do opt for permanent dye, choose a low-volume developer (10 or 20 volume). This will minimize damage to your hair.
* **Toner (Optional):** A toner can be used to neutralize any unwanted tones in your bleached hair before dyeing. For example, if your hair is very yellow, a purple-based toner can help to neutralize the yellow and create a more neutral base for your target color.
* **Color-Safe Shampoo and Conditioner:** After dyeing your hair, switch to color-safe shampoo and conditioner. These products are formulated to be gentle on colored hair and will help to prevent fading.
* **Deep Conditioner for Post Dyeing:** Have a deep conditioner on hand to provide extra hydration after you color your hair. Dying bleached hair strips the natural oils from your hair making it more prone to damage.

Step-by-Step Instructions for Dyeing Bleached Hair Back to Natural Color

Now that you’ve prepared your hair and gathered your supplies, it’s time to dye! Here’s a detailed step-by-step guide:

1. **Protect Your Skin and Clothes:** Wear an old t-shirt or a dyeing cape to protect your clothes. Apply a thin layer of petroleum jelly or a barrier cream along your hairline, ears, and neck to prevent the dye from staining your skin. Wear gloves to protect your hands.
2. **Mix the Dye:** Follow the instructions on the dye box to mix the dye and developer (if using). Be sure to use a non-metallic bowl and applicator brush.
3. **Apply the Dye:** Start by applying the dye to the roots of your hair, where the regrowth is. Use the applicator brush to apply the dye evenly, working in small sections. Once the roots are covered, apply the dye to the rest of your hair, working from the roots to the ends. Make sure to saturate all of your hair with dye.
4. **Massage the Dye:** Once you’ve applied the dye to all of your hair, gently massage it in with your fingers to ensure even coverage. This will also help to lift the hair cuticle and allow the dye to penetrate more effectively.
5. **Wait for the Processing Time:** Follow the instructions on the dye box for the recommended processing time. This is usually around 20-30 minutes for demi-permanent dye and 30-45 minutes for permanent dye. Do not exceed the recommended processing time, as this can damage your hair.
6. **Rinse Thoroughly:** Once the processing time is up, rinse your hair thoroughly with cool water until the water runs clear. This can take several minutes.
7. **Apply Conditioner:** After rinsing, apply the conditioner that came with the dye or a color-safe conditioner. Leave it on for a few minutes, then rinse thoroughly.
8. **Dry and Style:** Gently towel-dry your hair and style as usual. Avoid using heat styling tools for the first few days after dyeing, as this can cause the color to fade.

Tips for Achieving the Best Results

Here are some additional tips to help you achieve the best possible results:

* **Work in Sections:** Dividing your hair into small sections will make it easier to apply the dye evenly and ensure that all of your hair is saturated.
* **Use a Mirror:** Use a mirror to check the back of your head and make sure you haven’t missed any spots.
* **Don’t Overlap:** When applying dye to the roots, avoid overlapping onto previously dyed hair. This can cause the color to become uneven.
* **Be Patient:** Dyeing your hair is a process that takes time and patience. Don’t rush it, and be sure to follow the instructions carefully.
* **Consider Professional Help:** If you’re feeling unsure about dyeing your hair yourself, consider going to a professional stylist. They can help you choose the right color and technique, and ensure that you get the best possible results.

Dealing with Common Problems

Even with careful preparation and application, things can sometimes go wrong. Here are some common problems and how to fix them:

* **Hair is Too Dark:** If your hair turns out darker than you expected, you can try using a clarifying shampoo to fade the color slightly. You can also use a color remover, but be careful as this can be damaging to your hair. If the color is only slightly too dark, it will likely fade over time with regular washing.
* **Hair is Too Light:** If your hair is too light, you can simply re-dye it with a darker shade. Be sure to do a strand test first to make sure you like the color.
* **Hair is Green:** If your hair turns green, you can use a red-based toner or dye to neutralize the green. You can also try using a tomato juice mask, as the red pigments in tomato juice can help to counteract the green.
* **Uneven Color:** If your hair is unevenly colored, you may need to see a professional stylist to even it out. They can use techniques like color correction and balayage to blend the colors together.
* **Dry and Damaged Hair:** If your hair is dry and damaged after dyeing, focus on deep conditioning treatments and avoid heat styling. You can also use a leave-in conditioner to help hydrate and protect your hair.

Maintaining Your New Hair Color

Once you’ve achieved your desired hair color, it’s important to maintain it to prevent fading and damage. Here are some tips:

* **Use Color-Safe Shampoo and Conditioner:** As mentioned earlier, color-safe shampoo and conditioner are essential for preventing fading.
* **Wash Your Hair Less Often:** Washing your hair too often can strip it of its natural oils and cause the color to fade. Try to wash your hair only 2-3 times a week.
* **Use Cool Water:** Hot water can open the hair cuticle and cause the color to fade. Wash your hair with cool or lukewarm water instead.
* **Protect Your Hair from the Sun:** The sun can also cause hair color to fade. Wear a hat or use a UV protectant spray when spending time outdoors.
* **Avoid Chlorine:** Chlorine can strip hair of its color and cause it to become dry and damaged. Wear a swimming cap when swimming in a chlorinated pool.
* **Get Regular Trims:** Regular trims will help to remove split ends and prevent breakage, keeping your hair healthy and vibrant.
* **Deep Condition Regularly:** Deep conditioning treatments will help to hydrate and nourish your hair, preventing dryness and damage.
* **Touch Up Roots as Needed:** Depending on how fast your hair grows, you’ll need to touch up your roots every 4-6 weeks to maintain a consistent color.

The Science of Hair Color: A Deeper Dive

Understanding the science behind hair color can help you make more informed decisions about your hair dyeing journey. Here’s a closer look at the key concepts:

* **The Hair Structure:** Hair is composed of three layers: the cuticle, the cortex, and the medulla. The cuticle is the outermost layer and is made up of overlapping scales that protect the inner layers. The cortex is the middle layer and contains the hair’s pigment (melanin). The medulla is the innermost layer and is only present in some hair types.
* **Melanin:** Melanin is the pigment that gives hair its natural color. There are two types of melanin: eumelanin (which produces brown and black pigments) and pheomelanin (which produces red and yellow pigments). The combination of these two pigments determines the overall color of your hair.
* **Hydrogen Peroxide:** Hydrogen peroxide is the active ingredient in most hair dyes and lighteners. It works by opening the hair cuticle and allowing the dye molecules to penetrate the cortex. It also oxidizes the melanin, which lightens the hair’s natural color.
* **Ammonia:** Ammonia is another common ingredient in hair dyes. It helps to open the hair cuticle and allows the dye molecules to penetrate the cortex more easily. It also helps to activate the hydrogen peroxide.
* **Dye Molecules:** Hair dyes contain various dye molecules that deposit color into the hair shaft. These molecules can be either permanent, demi-permanent, or temporary, depending on their size and how they interact with the hair cuticle.

Going to a Professional Colorist

While dyeing your hair at home can be a cost-effective option, there are times when it’s best to seek professional help. Consider going to a professional colorist if:

* **You’re Making a Drastic Color Change:** If you’re going from very light blonde to very dark brown, or vice versa, it’s best to leave it to the professionals. They have the expertise and experience to ensure that the color is applied evenly and that you get the desired results.
* **You Have Damaged Hair:** If your hair is already damaged from bleaching or other chemical treatments, a professional colorist can assess the condition of your hair and recommend the best course of action. They can also use specialized products and techniques to minimize further damage.
* **You’re Not Confident in Your Skills:** If you’re feeling unsure about dyeing your hair yourself, it’s always better to err on the side of caution and go to a professional. They can help you choose the right color and technique, and ensure that you get the best possible results.
* **You Want a Complex Color:** If you’re looking for a complex color with multiple tones and highlights, a professional colorist can create a custom color that is tailored to your individual needs.
