Correct answer: B. Fusion extensions

Fusion extensions involve attaching individual strands of extension hair to the client's natural hair using a keratin-based bond that is melted with a specialized heat tool. This creates a strong, durable, and natural-looking attachment.

Why the other options are wrong

  • A. Sew-in extensions involve braiding natural hair into cornrows and then sewing wefts onto the braids.
  • C. Tape-in extensions use adhesive strips to attach wefts of hair.
  • D. Micro-link extensions use small metal or silicone-lined beads to attach hair.

Fusion Hair Extensions

A hair extension method where individual strands of extension hair, tipped with a keratin-based bond, are attached to small sections of the client's natural hair using a specialized heating tool to melt and fuse the bond.

  • Uses keratin bonds.
  • Requires a heat tool for application.
  • Creates very natural movement.
  • Can last 3-5 months with proper care.

Memory trick: Fusion: Fuse with heat for a natural blend.
