The Grading Myth & Factory Processing

◆ The "10A-12A" Marketing Fiction

There is no governing body or laboratory standard for hair grading. Numbered grades (8A through 12A) are arbitrary labels invented by trading brokers to justify pricing tiers on identical bundles.

◆ Acid Baths vs. Mechanical Alignment

Acid-Stripped Hair: Floor sweepings and mixed-source hair have reversed cuticles. To prevent tangling, factories bathe the hair in hydrochloric acid to burn away the cuticle completely. The hair is then dipped in heavy industrial silicone to simulate softness. Within 3 to 4 washes, the coating dissolves, leaving coarse, unmanageable hair that knots permanently at the neck.

True Cuticle-Aligned Hair: Hair collected with roots and tips oriented in the same natural direction. Cuticles remain intact and flat without requiring chemical acid stripping or silicone masks.

The 5-Minute At-Home Verification Checklist

Test a sample strand or bundle before scheduling full installation:

Friction Test
Slide root→tip, then reverse. Drag = intact cuticle.
Wash Test
Clarifying wash + blow-dry. Dry/shed = silicone-coated.
Burn Test
Ignite a snippet. Ash = human. Plastic bead = synthetic.

◆ 1. The Bi-Directional Friction Test

  • Intact Cuticle Smooth downward; drag upward against the scales.
  • Acid-Stripped Slick in both directions — protective barrier missing.

◆ 2. The Clarifying Wash Test

  • High Grade Retains texture and flex without synthetic coating.
  • Silicone-Coated Feels dry, catches on itself, sheds during comb-through.

◆ 3. The Ash Burn Test

  • 100% Human Hair Burns rapidly, smells like sulfur, crumbles into fine ash.
  • Synthetic / Blend Melts into a hard plastic bead with dark smoke.

Density Standards & End Ratios

Low-grade bundles are cut thick at the top with heavily tapered ends to reduce weight costs.

Maintenance Protocol

◆ The Golden Rules:
  • Never sleep with wet or damp hair.
  • Tie hair in a loose low braid or bun using silk scrunchies before bed.
  • Avoid washing with sulfates or applying high heat above 180C (350F).
