What is Blondor Multi Blonde Powder?
Blondor Multi Blonde Powder is a hair lightening product. Professionals use it to lift natural and artificial hair color. It gives clean, even results. It works best when mixed with the right developer in the correct ratio. This helps avoid damage and gives a smooth blonde result.

Why Mixing Ratio Matters in Hair Bleaching
The mixing ratio affects the final hair result. If the ratio is wrong, the hair can become patchy or dry. A correct ratio ensures better lightning, less damage, and a smooth application. Most professionals use a ratio of 1:1.5 or 1:2. This means for every 1 gram of powder, you mix 1.5 to 2 grams (or ml) of developer.
Common Blondor Mixing Ratios
1:1.5 Ratio
Use this when you want more control. The thicker mixture works well for highlights. It stays in place and doesn’t drip.
1:2 Ratio
Use this when you want stronger lifting. It spreads more easily. This ratio is good for full-head bleaching or balayage.
Choosing Developer Strength
- Use 6% (20 Vol) for mild lightning.
- Use 9% (30 Vol) for stronger lightning.
- Use 12% (40 Vol) with care, only on healthy hair.
Mixing with the correct strength of developer depends on hair type, color history, and target shade.
Step-by-Step: How to Mix Blondor Multi Blonde Powder
Step 1: Choose the Right Ratio
Decide if you want a 1:1.5 or 1:2 ratio. Most users start with 30g of powder.
Step 2: Measure the Powder
Use a digital scale. Do not guess. For example, 30g of powder is standard.
Step 3: Calculate the Developer Amount
Use the formula:
Developer = Powder × Ratio
If the ratio is 1.5:
30g × 1.5 = 45g of developer
If the ratio is 2:
30g × 2 = 60g of developer
Step 4: Mix Well
Stir the mixture until smooth. Make sure there are no lumps. Apply the bleach immediately after mixing.
How Long to leave it on the Hair?
Check hair every 5–10 minutes. Do not leave the mixture on the hair for more than 50 minutes. Rinse with cool water and use a moisturizing shampoo. Follow with a deep conditioner.

Why I Recommend This as a Textile Engineer and Fashion Designer
As a textile engineer and fashion designer, I always focus on consistency in production. Just like fabric dyeing depends on precise dye ratios, hair bleaching also needs accurate powder-to-developer ratios. Mistakes in calculation can lead to over-processed results, just as wrong dye recipes ruin fabric quality. The approach is the same: measure right, mix right, and apply right.
Conclusion
Using the correct Blondor Multi Blonde Powder mixing ratio is key to safe and effective hair lightening. Whether you choose a 1:1.5 or 1:2 ratio, always measure properly. Use a developer strength that fits your hair condition. Mixing correctly protects hair and gives you beautiful, even blonde results. Use a mixing ratio calculator to make the process easy and exact.
