  1. AApply a heat protectant spray
  2. BTrim the extension to blend with natural hair
  3. CApply a bonding adhesive to reinforce the attachment
  4. DUse a specialized heating tool to melt and mold the bond
Show answer & explanation

Correct answer: D. Use a specialized heating tool to melt and mold the bond

In the fusion method, after placing the keratin-tipped extension strand, a specialized heating tool is used to melt the keratin bond, allowing it to fuse and mold securely around the client's natural hair strands.

Why the other options are wrong

  • A. Heat protectant is applied before heat styling the hair, not directly to the bond for attachment.
  • B. Trimming is done after all extensions are applied and bonded, for blending and shaping.
  • C. Bonding adhesive is used in other methods (e.g., bonding/weaving), but fusion uses keratin and heat, not liquid adhesive at this stage.

Fusion Hair Extensions

A method of attaching hair extensions using a keratin-based bond that is melted with a heating tool to fuse the extension strand to the client's natural hair.

  • Creates small, discreet, and flexible attachments.
  • Requires specialized tools to melt and mold the keratin.
  • Typically lasts 3-5 months with proper care and maintenance.

Memory trick: Fusion means FUSE with HEAT.
