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. By purchasing Beauvoir hair, you agree to follow our care instructions and to review them with your client.
