The Basics of Hair Bleaching

First things first, it’s important to understand what exactly happens when you use bleach on your hair.

Hair bleach works by breaking down the natural pigment in your hair, called melanin, which gives your hair its color. This is a chemical reaction that involves an oxidizing agent (typically hydrogen peroxide) and a compound known as an alkalizing agent (like ammonia). The alkalizing agent raises the hair cuticle, allowing the bleach to penetrate and dissolve the melanin.

There are several different types of hair bleach products available on the market. These include powder bleach, cream bleach, oil bleach, and bleach baths.

Powder bleach is the most common form used in salons and is generally mixed with a developer to create a paste. Cream bleach, on the other hand, is less harsh on the scalp and hair. Oil bleach is typically used for more sensitive scalps, while a bleach bath is a milder form of bleach combined with shampoo, mainly used to correct color mistakes or to lighten hair slightly.

Remember, bleaching is a serious process and should be treated as such. Using the wrong products or incorrect techniques can cause severe damage your hair.

But don’t worry! With the right information, you can safely transform your dark mane into stunning blonde locks.


Assessing Your Hair Type and Condition

Before we get into the nitty-gritty of the actual bleaching process, it’s crucial to assess your hair type and condition. This is an essential step you shouldn’t skip, as it will determine how your hair responds to the bleach.

Start by conducting a strand test. This involves applying the bleach to a small, inconspicuous strand of hair and observing the results. It can give you a rough idea of how long it will take for the rest of your hair to reach the desired color and can also reveal any potential adverse reactions your hair might have to the bleach.

Next, evaluate the overall health of your hair. Untreated, healthy hair generally takes to bleach better than damaged or chemically treated hair. If your hair is already dry, brittle, or damaged, you might want to reconsider bleaching, as it could exacerbate these issues. 

Remember, bleaching is a pretty intense process, and it will have an impact on your hair’s health and condition.

Determine your hair type – is it fine, thick, coarse, or somewhere in between? This can influence how quickly and effectively the bleach works. Fine hair tends to lighten quickly, while coarse hair may require a longer processing time.

Finally, consider whether your hair has been dyed in the past. Color-treated hair can be more challenging to bleach, and it may be harder to achieve the desired blonde hues. You may need a color remover or hair stylist help if you’re dealing with old dye jobs.

Remember, it’s always best to consult with a professional if you’re unsure, especially if this is your first time bleaching your hair.


Gathering the Necessary Supplies

You’ve determined your hair is ready for bleaching. Great! Now, it’s time to gather all the right products. Here’s a list of what you’ll need:

  1. Bleaching Powder: This is the key ingredient that will lighten your hair. Look for a reputable brand that is known for its high quality and effectiveness.
  2. Developer or Peroxide: This is mixed with the bleach powder to activate it. It comes in different volumes, usually ranging from 10 to 40. The higher the volume, the more it lightens, but it also causes more damage. For darker hair, a volume of 20 or 30 is typically recommended.
  3. Tint Brush: This will help you apply the bleach evenly to your hair.
  4. Mixing Bowl: Preferably plastic, as metal can react with the bleach.
  5. Gloves: To protect your hands from the bleach.
  6. Plastic Shower Cap or Aluminum Foil: To cover the bleached sections and prevent the bleach from getting on the rest of your hair.
  7. Hair Sectioning Clips: To help you separate your hair into sections for easier application.
  8. Purple Shampoo and Conditioner: After bleaching, purple shampoo and conditioner can help neutralize any yellow or orange tones in your hair.
  9. Deep Conditioning Treatment or Moisturizing Mask: Bleach can be drying, so it’s important to have a moisturizing deep conditioner or hair mask on hand to restore your hair’s moisture after the process.
  10. Towel and Old Shirt: Bleaching can get messy, so it’s advisable to wear an old shirt and have a towel nearby.

Remember to always read the instructions on the bleach and developer packaging thoroughly before starting. Different brands may have different ratios of developer to bleach, so ensure you’re mixing correctly to get the best results.


Step-By-Step Guide To Bleaching Dark Hair

Step 1: Prepare Your Space and Wear Protective Clothing

Start by preparing your space. Lay down old towels or newspaper to catch any spills. Put on your old shirt and gloves to protect your skin and clothing.

Step 2: Mix the Bleach and Developer

Next, mix your bleach and developer in a plastic bowl according to the instructions on the packaging. Be sure to mix thoroughly until you’ve got a smooth, creamy consistency.

Step 3: Section Your Hair

Divide your hair into sections. This will make the bleach easier to apply and ensure you don’t miss any spots. Use your sectioning clips to keep the sections separate.

Step 4: Apply the Bleach

Start applying the bleach mixture from the tips of your hair and work your way up to the roots. This is because the heat from your scalp will cause the roots to lighten faster. Make sure all your hair is evenly coated with the bleach.

Step 5: Wrap Your Hair

Once you’ve applied the bleach, wrap your hair in a plastic cap. This will keep the heat in and help the bleach to work more effectively.

Step 6: Wait

Leave the bleach on your hair for the amount of time specified in the instructions. Be sure to check your hair every 10 minutes to see how it’s progressing.

Step 7: Rinse Out the Bleach

When the time is up, thoroughly rinse the bleach out of your hair with warm water. Be careful not to get any in your eyes.

Step 8: Apply Purple Shampoo

Wash your hair with purple shampoo to help neutralize any yellow or brassy tones. Follow this up with a deep conditioner or hair mask to replenish any lost moisture.

Step 9: Dry and Style

Finally, gently towel dry your hair and style it as desired. You should now have a beautiful blonde hair color.

Remember, everyone’s hair reacts differently to bleach, so your results may vary. You may need to repeat the process if the final outcome isn’t as light as you wanted. However, waiting a couple of weeks between treatments is the safest way to avoid damaging your hair.


Potential Challenges When Bleaching Dark Hair

Bleaching dark hair to a light blonde color can be complex and may present several challenges. Firstly, achieving the desired result might take multiple bleach applications, which can be time-consuming and damaging to hair. Each application strips away color and moisture, which may result in hair becoming dry, brittle, and prone to breakage.

Secondly, managing the post-bleach color can be quite a task. You might have to deal with undesired brassy or yellow tones. Purple shampoo and conditioner can help keep these tones at bay, but it’s an ongoing process.

Lastly, maintaining the health of your hair post-bleaching is another challenge. Regular deep conditioning and hair masks are essential to replenish lost moisture and preserve the strength of your hair. Limiting the use of heat styling tools is also recommended, as they can cause further damage to bleached hair.

Remember, everyone’s hair reacts differently to bleach, so your results may vary. Consult with a professional if you’re experiencing substantial challenges or if the health of your hair is a concern.

When lightening dark brown hair, it’s crucial to choose a quality hair bleach specifically designed for the purpose. Opt for a reputable brand with conditioning agents to minimize damage. Select a developer strength based on your hair type and desired results (e.g., 20-30 volume for dark brown hair).

How do you bleach dark hair without it turning orange?

To bleach dark hair without it turning orange, choose a high-quality bleach product and a developer strength appropriate for your hair type.
