Question 1

A fusion/bonded extension application requires which specialized combination of tools?

Accepted Answer

A heat fusion iron/wand and extension removal pliers

Answer

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?

Accepted Answer

At least 1/4 inch (about 0.5 cm) from the scalp

Answer

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?

Accepted Answer

Every 6–8 weeks

Answer

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:

Accepted Answer

Professional extension bond remover solution designed for adhesive tape

Answer

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

Accepted Answer
