Question 1

What is the correct procedure if a client reports a burning sensation during a relaxer service?

Accepted Answer

Immediately rinse the product from the hair and scalp with lukewarm water

Answer

If a client reports burning or irritation during a relaxer service, the product must be immediately rinsed from the hair and scalp with lukewarm water. Chemical burns from relaxers can be severe, and client safety always comes first.

Question 2

What is a thio relaxer?

Accepted Answer

A relaxer that uses ammonium thioglycolate as the active ingredient and is similar to perm chemistry

Answer

A thio relaxer uses ammonium thioglycolate (the same reducing agent as alkaline perms) to break disulfide bonds. Unlike hydroxide relaxers, thio relaxers require a separate neutralization step and the process is potentially reversible.

Question 3

What is the key difference between hydroxide relaxers and thio relaxers in terms of bond chemistry?

Accepted Answer

Hydroxide relaxers convert disulfide bonds to lanthionine bonds permanently; thio relaxers break and reform disulfide bonds

Answer

Hydroxide relaxers break disulfide bonds and convert them to single lanthionine bonds — a permanent, irreversible change. Thio relaxers break disulfide bonds but can reform them with a neutralizer, similar to perming chemistry.

Question 4

What rod placement pattern uses rods positioned in rows following the head's curvature?

Accepted Answer

Straight set or nine-section pattern

Answer

The straight set (also called the nine-section or basic pattern) places rods in straight, parallel rows following the curvature of the head. It is the most common and traditional perm wrapping pattern.

Question 5

What is a brick-lay perm wrap pattern?

Accepted Answer

Rods are offset in alternating rows like bricks in a wall to avoid visible splits between sections

Answer

The brick-lay pattern offsets each row of rods so they sit between the partings of the row above, similar to a brick wall. This prevents visible splits or separations in the finished curl pattern.
