Bleaching hair can be a game-changer, whether you’re aiming for a bold new look or prepping for a vibrant color. However, it’s not as simple as slapping on some bleach and hoping for the best.
If done incorrectly, bleaching can damage your hair or lead to uneven results. That’s why I’m here to guide you through the process step by step, ensuring you achieve stunning results while keeping your hair healthy.
What You Need to Know Before Bleaching Your Hair
Before diving into the process, it’s essential to understand what bleaching does to your hair. Bleach works by stripping away your hair’s natural pigment, which can weaken its structure. Therefore, preparation is key to minimizing damage.
Things You’ll Need:
- Hair bleach powder
- Developer (20 or 30 volume)
- Mixing bowl and brush
- Gloves
- Old towel or cape
- Clips to section hair
- Toner (optional)
- Deep conditioning treatment

Step-by-Step Guide on How to Bleach Hair
Step 1: Perform a Strand Test
First, always do a strand test to see how your hair reacts to the bleach. This step helps you determine the processing time and avoid surprises.
Step 2: Protect Your Skin and Clothes
Next, put on gloves and drape an old towel or cape over your shoulders. Apply petroleum jelly around your hairline and ears to protect your skin from irritation.
Step 3: Mix the Bleach
In a mixing bowl, combine the bleach powder and developer according to the instructions on the packaging. Stir until you achieve a smooth, lump-free consistency.
Step 4: Section Your Hair
Using clips, divide your hair into four sections. This ensures even application and prevents missed spots.
Step 5: Apply the Bleach
Starting from the ends (which are usually darker), apply the bleach mixture using a brush. Avoid the roots initially, as they process faster due to heat from your scalp.
Step 6: Monitor the Process
Check your hair every 5-10 minutes to avoid over-processing. Once the ends reach a light yellow or pale blonde shade, apply bleach to the roots.
Step 7: Rinse and Condition
Once you achieve the desired lightness, rinse your hair thoroughly with cool water. Follow up with a deep conditioning treatment to restore moisture.
Aftercare Tips for Bleached Hair
Bleaching can leave your hair dry and brittle, so proper aftercare is crucial. Here are some tips:
- Use sulfate-free shampoos and conditioners.
- Apply a hair mask weekly to maintain hydration.
- Avoid heat styling tools as much as possible.
- Use a purple toner to neutralize brassy tones.
Common Mistakes to Avoid When Bleaching Hair
- Skipping the strand test.
- Applying bleach to dirty hair.
