Bleaching Experiment: Achieving Level 8 Blonde with 10 Vol (3%) Developer on Vietnamese Raw Hair

For professional hair vendors and salon owners, the true test of quality isn't in the texture of a new bundle, but in its lifting capacity. Can the hair withstand chemical processing while maintaining its structural integrity?

Today, VietsilkHair is launching a transparent bleaching series. We start with the most gentle approach: 10 Volume (3%) Developer on our 12-inch Natural Color Raw Hair bundle.

1. The Experiment Setup

We chose a low-concentration developer to prove a point: High-quality raw hair doesn't need harsh chemicals to reach beautiful light tones.

• Hair Sample: 12-inch VietsilkHair Raw Bundle (Natural Black/Brown).

• Formula: Premium White Bleach Powder + 3% (10 Vol) Oxygen.

• Total Time: 45 minutes.

2. The Step-by-Step Transition

Transparency is key to building trust. We monitored the hair at three critical intervals to show the gradual and healthy lift of Vietnamese hair.

• 15 Minutes: The hair begins to open its cuticles. The natural black pigments start transitioning into a warm brown/gold undertone.

• 30 Minutes: A significant jump. The hair reaches a solid Level 6-7. At this stage, the hair remains incredibly strong and elastic.

• 45 Minutes (Final Result): The bundle successfully hits Level 8 on the international hair color chart.

3. Quality Assessment: Beyond the Color

Achieving Level 8 is one thing; keeping the hair healthy is another. After rinsing and air-drying, the results were undeniable:

• Natural Shine: Even after bleaching, the hair retains a healthy luster under natural sunlight. This is a hallmark of 100% cuticle-aligned hair.

• Soft Texture: There is zero "crunchiness" or frizz. The strands remain silky and easy to comb through.

• Strength: No breakage or "gumminess" was observed, proving that the hair’s cortex is still intact and ready for further toning or styling.

4. Why This Matters for Your Hair Business

As a hair vendor, your reputation depends on the longevity of the products you sell. Choosing hair that lifts easily with low-volume developers means:

1. Lower Damage Risk: You can offer your clients blonde shades without compromising hair health.

2. Color Versatility: Level 8 is the perfect "canvas" for Honey Blonde, Ash Brown, or vibrant Ombre colors.

3. Cost Efficiency: Faster lifting times and less "correction" work needed.
