CHS Hair Extensions & Additions 2 — Questions and Answers
Question 1: A fusion/bonded extension application requires which specialized combination of tools?
- A flat iron and tail comb only
- A sewing needle and extension thread
- A heat fusion iron/wand and extension removal pliers (Correct answer)
- A hooded dryer and pin-tail comb
Correct answer: A heat fusion iron/wand and extension removal pliers
Fusion extensions require a heat fusion wand to melt and apply the keratin bond during installation, and specialized pliers along with bond remover solution are used during removal.
Question 2: To minimize scalp stress and prevent root breakage, extension bonds should be placed at least how far from the scalp?
- Flush against the scalp
- At least 1/4 inch (about 0.5 cm) from the scalp (Correct answer)
- At least 2 inches from the scalp
- Exactly at the scalp line for a seamless look
Correct answer: At least 1/4 inch (about 0.5 cm) from the scalp
Placing extension bonds at least 1/4 inch from the scalp prevents mechanical stress at the hair root and reduces the risk of traction alopecia and breakage.
Question 3: How often should micro-link extensions typically be maintained (moved up) to account for natural hair growth?
- Every 2–3 weeks
- Every 6–8 weeks (Correct answer)
- Every 4–6 months
- Only when the client notices slippage
Correct answer: Every 6–8 weeks
As natural hair grows approximately 1/2 inch per month, micro-link beads travel down the hair shaft and should be repositioned every 6–8 weeks to stay close to the scalp and prevent tangling.
Question 4: To safely remove tape-in extensions without damaging the natural hair, a stylist should use:
- Acetone-based nail polish remover
- Professional extension bond remover solution designed for adhesive tape (Correct answer)
- Boiling hot water applied to the bonds
- A flat iron on high heat to release the tape
Correct answer: Professional extension bond remover solution designed for adhesive tape
Professional extension bond remover solutions are formulated to break down the adhesive in tape-in extensions gently and safely without stripping the natural hair or causing breakage.
Question 5: Sew-in weave extensions are installed by first:
- Applying adhesive directly to the scalp along the hairline
- Creating braided cornrow tracks that serve as the foundation (Correct answer)
- Sectioning the hair and applying tape along each part
- Washing the hair and blow-drying it completely straight
Correct answer: Creating braided cornrow tracks that serve as the foundation
In a sew-in weave, natural hair is braided flat against the scalp into cornrow tracks, and then wefts of extension hair are sewn directly onto those braids using a needle and thread.
Question 6: Which single factor has the greatest influence on how long hair extensions will last and look their best?
- The brand or manufacturer of the extensions
- Proper installation technique combined with diligent at-home maintenance (Correct answer)
- The natural color and texture of the client's hair
- The season or climate in which they are applied
Correct answer: Proper installation technique combined with diligent at-home maintenance
Correct installation by a trained stylist and consistent at-home care — including proper washing, drying, and brushing — are the primary determinants of extension lifespan and appearance.
Question 7: Extensions applied with excessive tension close to the scalp over time can cause which serious hair loss condition?
- Seborrheic dermatitis
- Androgenetic alopecia
- Traction alopecia (Correct answer)
- Tinea capitis
Correct answer: Traction alopecia
Traction alopecia is hair loss caused by repeated or prolonged tension on the hair follicle, and improperly applied tight extensions are a common cause.
