A cosmetologist is preparing to apply a full head of permanent hair extensions using a method that involves attaching individual strands of extension hair to the client's natural hair with a small, specialized cylindrical bead. Which application method is being described?

  1. ATape-in extensions
  2. BFusion (Keratin bond) extensions
  3. CMicro-link (I-tip) extensions
  4. DWeft (Sew-in) extensions
Show answer & explanation

Correct answer: C. Micro-link (I-tip) extensions

Micro-link, also known as I-tip or cylinder extensions, involves attaching individual strands of extension hair to small sections of the client's natural hair using a small metal or silicone-lined bead/cylinder, which is then clamped shut to secure the extension.

Why the other options are wrong

  • A. Tape-in extensions use adhesive strips to attach wefts of hair.
  • B. Fusion extensions use a keratin bond that is melted to attach individual strands.
  • D. Weft (sew-in) extensions involve braiding the natural hair into cornrows and then sewing wefts of hair onto the braids.

Micro-link (I-tip) Extensions

A hair extension method where individual strands of extension hair (I-tips) are attached to small sections of natural hair using a small, specialized metal or silicone-lined bead/cylinder.

  • No heat or glue required for application.
  • Allows for 360-degree movement of hair.
  • Requires regular maintenance for re-tightening or repositioning beads.
  • Can be reused if maintained properly.
