- 1low ph wavesLow-pH waves use an alternative formula for their waving solutions. Instead of Ammonium Thioglycolate, low-pH waves use sulfates, sulfites and bisulfites as their primary ingredients.
- 2Metal hydroxide relaxersMetal hydroxide relaxers are ionic compounds formed by a metal, sodium, potassium, or lithium, which is combined with oxygen and hydrogen.
- 3Book end wrapPerm wrap in which one end paper is folded in half over the hair ends like an envelope, eliminates excess paper and can be use with short rods or very short hair lengths.
- 4Normalizing lotionsConditioners with an acidic pH that restores the hair's natural pH before the final neutralizing shampoo for hydroxide relaxers.
- 5Off-base placementsBase control in which the hair is wrapped at 45 degrees below the base section's center so the rod is positioned completely off its base.
- 6Peptide bondsAlso known as an end bond; chemical bonds that join amino acids to each other, end to end, to form a polypeptide chain.
- 7Permanent wavingAdds wave or curl to the hair; also used to loosen curls. A two step process where the hair undergoes a physical change caused by wrapping the hair on perm rods then undergoes a chemical change caused by the application of permanent waving solution and neutralizer.
- 8Polypetide chainsLong chain of amino acids linked by peptide bonds.
- 9Side bondsBonds that cross-link polypeptide chains and are responsible for the extreme strength and elasticity of human hair; accounts for about one third of hair's overall strength.
- 10Soft benderAlso known as flexible foam rods; a tool about 12 inches long with a uniform diameter along the rods entire length.
- 11Soft curl permanentAlso called chemical curl reformation service; this thio-based chemical process loosens very curly hair into larger soft curls or waves.
- 12Thiogylcolic acidA colorless liquid with a strong, unpleasant odor, is the most common reducing agent.
- 13Thio neutralizationRelies on an oxidation process to stop the action of the relaxer solution and rebuild the hairs new form.
- 14Thio relaxersUses reduction and oxidation to break the disulfide bonds and then reform them to a more relaxed hair texture. Uses the same AGT that is used in permanent waving but at a higher concentration and higher pH.
- 15Thio free wavesPerms that use an ingredient other than ATG as the primary reducing agent, such as cysteamine or mercaptamine.
- 16True acid wavesHave a pH between 4.5 and 7.0 and require heat to process; they process more slowly than alkaline waves and do not usually produce as firm a curl as alkaline waves.
- 17ViscosityMeasurement of liquid's thickness or thinness.
- 18Weave techniqueThe volume and texture of a weave perm wind are created by weaving the hair to separate areas that will be permed and areas that will be left unpermed. The final result is loose, multi-textured, elegant curls supported by a brickwork perm underneath.
- 19Amino acidsForm the building blocks of protein; link together end to end like pop beads by strong chemical peptide bonds to form the polypeptide chains that comprise proteins.
- 20Alkaline wavesAlso known as cold waves; have a pH between 9.0 and 9.6, uses ATG as the reducing agent and processes without the addition of heat according the manufactures instructions.

- 22ActivatorsAlso known as booster, protinators or accelerators; powdered persulfate salts added to haircolor to increase its lightening ability.
- 23BaliageAlso known as a free form techinique; painting a lightener (usually a powdered off the scalp lightener) directly onto clean styled hair.
- 24IntensityThe strength of a color.
- 25Law of colorSystem for understanding color relationships.
- 26Demi permanent haircolorAlso known as no lift deposit only color; formulated to deposit but not lift natural hair color.
- 27Contributing pigmentAlso known as undertone; the varying degrees of warmth exposed during a permanent color or lightening process.
- 28Tertiary colorIntermediate colors that can be achieved by mixing a secondary color and its neighboring primary color on the color wheel in equal parts.
- 29TonersSemi-permanent, demi-permanent and permanent haircolor products that are used primarily on pre-lightened hair to achieve pale and delicate colors.
- 30Complementary colorsA primary and secondary color positioned directly opposite of each other on the color wheel.
- 31Hydrogen peroxide developerOxidizing agent that when mixed with an oxidation haircolor supplies the necessary oxygen gas to develop the color molecules and create a change in natural color.
- 32Single-process haircoloringProcess that lightens and deposits color in the hair in a single application.
- 33Off the scalp lightenersAlso known as quick lighteners; powdered lighteners that cannot be used directly on the scalp.
- 34On the scalp lightenersLighteners that can be used directly on the scalp by mixing the lightener with activators.
- 35Line of demarcationA visible line separating colored hair from the new growth.
- 36Metallic haircolorsAlso known as gradual haircolors; haircolors containing metal salts that change hair color gradually by progressive build up and exposure to air creating a dull metallic appearance.
- 37Secondary colorColors obtained by mixing equal parts of two primary colors.
- 38Mixed melaninCombination of natural hair color that contains both pheomelanin and eumelanin.
- 39CortexThe middle layer of the hair that is located directly beneath the cuticle layer and is responsible for the incredible strength and elasticity of human hair.
- 40CuticleThe outermost layer of hair.
- 41MedullaInnermost layer of the hair that is composed of round cells. Fine and naturally blond hair to entirely lack a medulla. Only thick, coarse hair contains a medulla.
