• Hetto Nano Ring Human Hair Extensions: made with 100% Remy human hair, straight, soft, and easy to care for. They can be washed, dyed, straightened, and curled, always keeping the temperature below 180°C. • The nano tips allow for nano ring application, achieving a more transparent and undetectable finish without affecting the normal growth of your hair. • Each package includes 50 strands of 1g each (total 50g), individually pre-bonded to reduce hair loss. Installation by a professional is recommended for best results. • The extension beads may loosen or move due to daily styling, washing, and natural hair growth. They can be adjusted and pressed every two weeks as needed. Good care maintains the natural look and prolongs the lifespan of the extensions. • Installation without heat or chemicals, using silicone-lined rings to prevent hair damage. • Hair length: 14 inches (35 cm). • For external use only. Keep away from open flames or excessive heat sources.
