Learn how to choose and apply Truzone cream peroxide 3% and liquid peroxide 9% for safe, effective hair bleaching at home.
Quick answer
Use Truzone cream peroxide 3% (10 vol) for gentle toning or root touch-ups, and Truzone liquid peroxide 9% (30 vol) for full-head bleaching when you need more lift. Always mix with bleach powder in a non-metal bowl and apply to dry, unwashed hair.
Cream vs liquid peroxide: when to use each
Cream peroxide has a thicker consistency, making it ideal for on-scalp applications like root touch-ups or when you want more control. The 3% (10 vol) strength lifts only 1–2 levels, so it's best for depositing color or very gentle lightening.
Liquid peroxide is thinner and works well for off-scalp techniques like foils or full-head bleaching. The 9% (30 vol) strength lifts up to 3–4 levels, but it can be more runny, so avoid dripping onto skin or scalp.
Mixing ratios and safety
Always mix bleach powder and peroxide in a 1:2 ratio (one part powder to two parts peroxide) by volume, not weight. Use a digital scale or measuring spoons for accuracy.
Never mix peroxide with metal bowls or tools—use plastic or glass. Metal can cause a chemical reaction that weakens the bleach or damages hair.
Step-by-step guide to using Truzone peroxide for bleaching
- Choose your peroxide strength: Select cream peroxide 3% (10 vol) for gentle lift or toning; choose liquid peroxide 9% (30 vol) for stronger lift on darker hair. Do not use 30 vol on sensitive scalps. Check your starting hair color and desired result before choosing.
- Prepare your workstation: Wear gloves and an old shirt. Cover surfaces with newspaper. Have a non-metal bowl, a tint brush, sectioning clips, and a timer ready. Do not wash your hair beforehand—bleach works best on dry, unwashed hair. Missing a timer is a common mistake; set one for 30–45 minutes max.
- Mix the bleach and peroxide: Measure one part bleach powder and two parts Truzone peroxide by volume. Stir until smooth and creamy. Do not mix more than you can apply within 20 minutes. If the mixture looks runny, add a little more powder; if too thick, add a little more peroxide.
- Apply to hair sections: Divide hair into four sections. Starting at the back, apply the mixture from mid-lengths to ends, then to the roots (roots process faster). Use a tint brush for even coverage. Do not oversaturate. Applying to roots first can cause hot roots—always do mid-lengths and ends first.
- Process and check progress: Leave the bleach on for 20–45 minutes depending on your desired lift. Check every 10 minutes by wiping a small strand with a paper towel. Do not leave on longer than 45 minutes. If your hair feels gummy or stretchy, rinse immediately—it's over-processed.
- Rinse and tone: Rinse with lukewarm water until the water runs clear. Do not shampoo—use a gentle conditioner or a toner if needed. Follow with a deep conditioning treatment. Skipping conditioner can leave hair dry and brittle.
