---|---|
Is performed as part of your Guest consultation to test how the hair will respond to the chemical application | (Q)Preliminary strand test |
Is any illness caused by overexposure to certain products or ingredients | (Q)Occupational Disease |
Are the protein building blocks of hair and link together to form tiny fibers | Amino acids(Q) |
Also known as End Bonds, connect amino acids (end to end) that form polypeptides | Peptide bond(Q) |
Spiraling chain of amino acids; joined together by peptide bonds | Polypeptide chains(Q) |
Physical side bond (cross bond)easily broken by water or heat; reforms when hair cools and/or dries | Hydrogen Bonds(Q) |
Also known as Cross Bonds, connect polypeptide chains side-by-side; responsible for strength and elasticity | Side Bonds(Q) |
Weak physical side bonds (cross bonds) easily broken by change in pH; reform when pH balance is restored | Salt Bonds |
Strong chemical side bonds that can only be broken by chemical solutions | Disulfide Bonds(Q) |
Consists of two or more types of matter that are blended together, but not chemically altered; each part in the mixture maintains its own properties | Physical Mixture(Q) |
When a substance is able to be mixed with another substance | Miscible(Q) |
When a substance is able to not mix with another substance | Immiscible(Q) |
A measure of the acidity or alkalinity of a solution | Potential Hydrogen (pH)(Q) |
A scale ranging from 0 to 14 that measures if a product is an acid (0 to 6.9), an alkaline (7.1 to 14), or neutral (7) | pH Scale (Q) |
To chemically alter naturally curly or wavy hair into a straighter form | Chemical Relaxing |
The process of removing one sulfur atom and replacing it with a disulfide bond | Lanthionization |
Solutions with an acidic pH that restore the hair's natural pH after a hydroxide relaxer | Normalizing Lotions(Q) |
Use to help remove any remaining chemicals left in the hair after a hydroxide relaxer | Neutralizing Shampoo |
Also known as a Protective Base Cream, is an oily cream applied on the scalp / skin to protect from the chemicals in the relaxer | Base Cream |
Also known as Rebonding, is chemically restoring disulfide Bonds to harden into a new shape | Neutralizing |
Also called an acid/alkali neutralization reaction; it neutralizes any remaining alkaline residue left by the hydroxide relaxer and helps to restore the pH of the hair and scalp | Hydroxide Neutralization |
Measurement of how thick or thin a liquid is, and how that affects the liquids flow | Viscosity |
Relaxers with a high alkaline (pH) content; available in varying formulations | Hydroxide Relaxer |
A strong alkaline ingredient used in chemical relaxers | Sodium Hydroxide (Lye) |
A very strong alkaline ingredient used in chemical relaxers typically marked as no-mix, no-lye | Potassium Hydroxide / Lithium Hydroxide |
Relaxer requiring the mixing of two products; advertised as "no-lye " for sensitive skin | Guanidine Hydroxide |
Requires a protective base cream to be applied to the hairline and scalp; when a relaxer is labeled " base relaxer", it means the relaxer is too strong to be applied without the application of a base cream | Base Relaxer |
Also known as No-Lye Relaxers, do not require a base cream to be applied to the skin or scalp | No-Base Relaxer |
Known as thio relaxers by industry standards, are chemical compounds with the additive ingredient ammonia; considered to be a no-lye relaxer, suitable for soft curl reformation | Thioglycolate Relaxer |
A combination of ammonia and thioglycolic acid that creates a reducing agent used in permanent waves and relaxers | Ammonium Thioglycolate (ATG) |
A mild, alternative relaxer containing a low pH compatible with thio relaxers | Ammonium Bisulfite Relaxer |
An organic compound that is a colorless, flammable and pungent gas; present in the air and many food and beauty products | Formaldehyde |
Results from the oxidation of primary alcohols; there are several other chemicals in the class of highly reactive chemical compounds (composed of carbon, hydrogenand oxygen) | Aldehyde |
Chemically rearranging straight hair into a curly or wavy form | Permanent Waving |
A cream barrier applied around the hairline and ears to protect the skin from permanent wave lotions or haircolor | Protective Cream |
Chemical solution that stops the waving process of a permanent wave; rebuilds the bonds into their new form | Neutralizer |
The process of stopping a permanent wave and reform | Thio Neutralization |
Determines the required processing time and ensures that the desired curl has been achieved for a permanent wave service | Test Curl |
Products are manufactured 'without' the use of formaldehyde but could omit a formaldehyde gas upon use | Formaldehyde Free |
Also known as Cold Waves, processed without heat; the main ingredient is thioglycolic acid | Alkaline Waves |
The main active ingredient in true acid waves | Glycerl Monothioglycolate(GMTG) |
Permanent waves processed with the application of heat that have a pH range between 4.5 to 7; the main ingredient is typically glycerl monoglycolate (GMTG ); these acid waves process slower than alkaline waves | True Acid Waves |
Permanent waves processed without heat that have a pH ranging between 7.0 to 8.2; produce a firmer curl and process more quickly than true acid waves | Acid Balanced Waves |
Processed by the application of heat; hood dryer, heat processor | Endothermic Wave |
Processed by chemical reaction that releases heat; self heating | Exothermic Wave |
Use an ingredient other than ammonia to reduce the odor associated with ammonia perms | Ammonia-Free Waves |
A perm rod that has a small diameter in the center and a larger diameter increase throughout the length | Concave Rod |
Also known as Flexible Rods, foam-covered perm rods that are easily bent into different shapes and used for permanent waving; also known as flexible rods | Bender Rod |
A perm rod that has an even diameter/ width throughout the entire rod length | Straight Rod |
Also known as a Circle Rod, is a long, plastic rod that that is used to create spiral curls | Loop Rod |
Pliable foam rods that allow hair to be chemically altered, creating a soft-end result | Sponge Rod |
Requires hair to be placed between two end papers, one on each side of the hair strand | Double Flat Wrap |
Requires only one paper, which is folded in half much like a book | Book End Wrap |
Requires only one paper used in conjunction with either the double end or book end wraps | Single Flat Wrap |
Wrapping the hair from ends to scalp in overlapping concentric layers | Croquignole Wrap |
Consists of wrapping the hair at angle other than parallel to the length of the rod, which will create a coiling effect of the hair | Spiral Wrap |
The position of the perm rod; horizontal, vertical, or diagonal, within a section and/or parting | Base Direction |
