100

This is the weakest bond. 

What is the HYDROGEN BOND?

100

This makes up 65-95% of hair. 

What is PROTEIN?

100

This is an atom with an electron imbalance.

What is an ION?

100

In lightener, this controls how fast the desired result will be achieved.

What is DEVELOPER?

200

May contain 4-18 layers depending on hair texture.

What is the CUTICLE?

200

These are affected by a change in pH.

What are SALT BONDS?

200

This gives the hair the ability to stretch.

What is MOISTURE?

200

The pH scale is used to measure these 2 types of ions.

What are ACIDIC & ALKALINE?

200

The percentage in developer indicates the percentage of this to water.

What is HYDROGEN PEROXIDE?

300

Amino acids that can be created by the body.

What are NONESSENTIAL amino acids?

300

These are affected by reactive chemicals.

What are DISULFIDE BONDS?

300

These 3 PM products contain carbohydrates.

What are SCULPTING FOAM, SUPER SCULPT & REWORKS?

pH is only present when this is present.

What is WATER?

300

This PM color line has a synthetic beeswax base.

What is THE COLOR XG?

400

50 amino acids linked together by the peptide bond create this.

What is a PROTEIN?

400

7-9 of these twist & bind to form larger bundles to form microfibrils.

What are HELIX COILS?

400

This makes up only 1% of hair.

What is Melanin?

400

When hair is colored, these ions are removed.

What are POSITIVE IONS?

400

These are used as a pH adjuster.

What are MEAs?

500

Polypeptide chains are cross-linked by cross bonds & twist around each other to form this.

What is a HELICAL COIL?

500

7-9 macrofibrils twist & bind to form these. 

What are FIBRILS/CORTICAL CELLS?

500

This contains copper & turns orange in the oxidation process.

What is PHEOMELANIN?

500

When 2 negative ions repel each other, they cause the cuticle to do this.

What is SWELL?

500

This is used to increase the pH of the hair by removing positive ions.
