Chemical Texture Services Flashcards

What is a keratin smoothing treatment?

Answer: A semi-permanent service that infuses keratin protein into the hair to reduce frizz and smooth the cuticle

A keratin smoothing treatment applies a keratin-based formula to the hair, which is then sealed with a flat iron. It temporarily reduces frizz, smooths the cuticle, and adds shine for several weeks to months without permanently altering the bond structure.

What is the importance of proper sectioning and sub-sectioning for perm wrapping?

Answer: It ensures even saturation, consistent tension, and uniform curl results throughout the head

Proper sectioning ensures each subsection of hair fits correctly on the rod with even tension and consistent size. This results in uniform curl development, even saturation of perm solution, and a professional, balanced result.

What should a stylist check before performing any chemical texture service?

Answer: Hair and scalp condition, porosity, elasticity, texture, previous chemical history, and any contraindications

A thorough analysis before any chemical texture service should include assessing the hair's porosity, elasticity, texture, density, scalp condition, previous chemical services, and any contraindications such as metallic dyes or recent relaxer use.

What is the piggyback wrapping technique?

Answer: Using two rods per section — one for the root half and one for the ends — to accommodate long hair

The piggyback technique uses two rods per section for long hair. The hair is wound from the mid-shaft to the scalp on one rod, and the remaining ends are wound on a second rod. This prevents uneven processing on very long hair.

What chemical process occurs during the neutralization step of a perm?

Answer: Oxidation — disulfide bonds are reformed in their new configuration

Neutralization is an oxidation process. The neutralizer (usually containing hydrogen peroxide) adds oxygen to the broken sulfur bonds, causing them to reform as disulfide bonds in the new shape dictated by the perm rod.

How should perm solution be applied to the wrapped rods?

Answer: Applied carefully and evenly to each rod, ensuring thorough saturation without excess dripping

Perm solution should be applied methodically to each rod, ensuring complete, even saturation of all wrapped hair. The solution should be applied gently using an applicator bottle, avoiding oversaturation that causes dripping onto the scalp.
