CHS Hair Extensions & Additions 1 — Questions and Answers
Question 1: What is the primary adhesive used in keratin (fusion) hair extension application?
- Keratin bond heated with a fusion wand (Correct answer)
- Silicone-lined micro-bead
- Double-sided adhesive tape
- Thread sewn into a cornrow base
Correct answer: Keratin bond heated with a fusion wand
Keratin (fusion) extensions use a keratin-based adhesive bond that is melted and sealed using a specialized fusion heat wand.
Question 2: Micro-link (micro-bead) extensions secure added hair to natural hair using:
- Heat-activated keratin glue
- Small metal or silicone-lined rings clamped shut (Correct answer)
- Double-sided tape strips
- A bonding adhesive applied to the scalp
Correct answer: Small metal or silicone-lined rings clamped shut
Micro-link extensions use tiny metal or silicone-lined rings (beads) that are clamped shut around a small section of natural hair and the extension strand, requiring no heat or glue.
Question 3: Which type of hair is considered the gold standard for extensions due to intact, aligned cuticles and long-lasting quality?
- Synthetic heat-resistant fiber
- Non-Remy human hair
- Remy human hair (Correct answer)
- Virgin mixed-donor hair
Correct answer: Remy human hair
Remy human hair has all cuticles intact and running in the same direction, which prevents tangling, matting, and gives the most natural look and longest lifespan.
Question 4: Tape-in hair extensions are generally recommended to be repositioned as natural hair grows every:
- 2–3 weeks
- 6–8 weeks (Correct answer)
- 3–4 months
- Once a year
Correct answer: 6–8 weeks
As natural hair grows, tape-in extensions migrate away from the scalp and must be repositioned every 6–8 weeks to maintain a seamless blend and prevent stress on the hair.
Question 5: Which hair extension method is widely regarded as the least damaging to natural hair because it requires no glue, heat, or braiding?
- Keratin fusion bonds
- Micro-link bead extensions
- Clip-in extensions (Correct answer)
- Sew-in weave on cornrows
Correct answer: Clip-in extensions
Clip-in extensions attach and detach without any chemicals, heat, or tension on the scalp, making them the gentlest option and ideal for temporary use.
Question 6: In hair extension terminology, a 'weft' is best described as:
- A single strand of extension hair
- Hair strands sewn together along a horizontal track or band (Correct answer)
- A type of keratin adhesive bead
- A silicone ring used to clamp extensions
Correct answer: Hair strands sewn together along a horizontal track or band
A weft is a curtain of hair strands stitched or bonded together along a horizontal seam (track), which can then be sewn, glued, or clipped into the hair.
Question 7: Before applying hair extensions, the most critical initial step a stylist must perform is:
- Selecting the closest matching extension color
- Performing a thorough client consultation and hair and scalp analysis (Correct answer)
- Pre-sectioning the hair into quadrants
- Clarifying the hair with a chelating shampoo
Correct answer: Performing a thorough client consultation and hair and scalp analysis
A thorough consultation and scalp/hair health analysis ensures the client is a suitable candidate for extensions and allows the stylist to select the safest and most appropriate method.
