Beauvoir genius weft – 24” Single Donor Virgin in color #18 Dirty Blonde

A study in muted refinement. At couture length, Single Donor Virgin hair displays its most luxurious characteristics—complete strand unity, uninterrupted fluidity, and elevated softness. The ultra-thin Genius Weft remains invisible, even at maximum length.

Beauvoir’s precise, controlled production ensures flawless polyurethane curing, resulting in a beautifully soft yet durable weft.

Color #18 Dirty Blonde reaches peak sophistication at 24 inches: a smoked-neutral beige blonde with cool ash diffusion—quiet, expensive, and editorial.

The 24-inch Beauvoir Genius Weft contains approximately 94 grams of hair per pack. Each pack includes 2 × 20” wefts (40” total weft per pack), delivering luxurious fullness with a long, elegant fall.

Care, Performance & Limitations

Beauvoir extensions are a professional product and must be installed by a licensed stylist. Performance and longevity depend on proper installation, maintenance routines, and the use of compatible, extension-safe haircare products. Normal wear, changes in texture, and variations in tone can occur over time. Improper care, harsh products, excessive heat, or incorrect installation can contribute to dryness, tangling, or reduced longevity.
