- Sanitation
- Related: Disinfection, Cross-contamination
Cleaning surfaces and tools with soap and water or detergent to remove visible dirt, oil, and many germs. It reduces contamination but does not destroy all pathogens, so it comes before disinfection.
- Disinfection
- Related: Sanitation, Sterilization, Contact time
Using an EPA-registered hospital-grade product on cleaned nonporous implements to destroy most disease-causing organisms. It does not kill all bacterial spores, so it is not the same as sterilization.
- Sterilization
- Related: Disinfection, Nonporous implement
A process that destroys all microorganisms, including bacterial spores, on an implement. In salons it is used mainly for metal tools and is usually done with steam under pressure in an autoclave.
- EPA-registered hospital-grade disinfectant
- Related: Disinfection, Contact time
A product approved by the Environmental Protection Agency for use in healthcare settings. The label lists the pathogens it kills and the contact time required for salon use on nonporous tools.
- Contact time
- Related: EPA-registered hospital-grade disinfectant, Disinfection
The number of minutes an implement must stay completely wet with disinfectant, as stated on the product label. Shortening this time means pathogens may survive and the tool is not properly disinfected.
- Porous implement
- Related: Nonporous implement, Cross-contamination
A tool or material that absorbs liquid, such as wooden sticks, cotton, or paper files. Because disinfectant cannot penetrate it, a porous item must be discarded after one client rather than reused.
- Nonporous implement
- Related: Porous implement, Disinfection
A hard, smooth tool that does not absorb liquids, such as metal shears, combs, or glass. It can be cleaned, disinfected, and reused when salon rules are followed.
- Cross-contamination
- Related: Sanitation, Universal precautions
The spread of germs from one person or object to another by hands, tools, linens, or surfaces. Proper handwashing, cleaning, and disinfection break this chain in the salon.
- Universal precautions
- Related: Bloodborne pathogens, Cross-contamination
A safety practice of treating all blood and body fluids as if they carry infectious disease. It means wearing gloves and using barriers for every client, not only those who look sick.
- Bloodborne pathogens
- Related: Universal precautions, Cross-contamination
Disease-causing microorganisms carried in blood, such as hepatitis B, hepatitis C, and HIV. Salon workers prevent exposure by using gloves, barriers, and safe handling of sharp tools.
- Elevation
- Related: Blunt cut, Graduated haircut, Uniform layers
The angle at which a strand of hair is held away from the head while cutting. Low elevation builds weight and length; higher elevation creates layers and removes weight.
- Blunt cut
- Related: Elevation, Graduated haircut
A cut in which all hair is held at zero elevation and cut at one length, creating a solid, heavy perimeter line. It is also called a one-length cut.
- Graduated haircut
- Related: Elevation, Uniform layers
A cut that uses slight elevation, often at the back, so hair is stacked shorter at the perimeter and longer toward the crown. It creates a wedge or stacked shape with weight at the bottom.
- Uniform layers
- Related: Elevation, Graduated haircut
A layered cut in which hair is held at 90 degrees from the head throughout, so all layers are the same length. It adds movement and removes bulk evenly.
- Sectioning
- Related: Elevation
Dividing the hair into organized working areas with clips and partings before a service. Good sectioning keeps cuts balanced and makes the service faster and safer.
- Clipper-over-comb
- Related: Elevation
A cutting technique in which a comb is used as a guard and the clipper runs over it to shorten hair. It is common for tapering and blending short haircuts.
- Texturizing
- Related: Elevation
Removing bulk or creating irregular lengths so hair has movement, softness, or a piecey look. It is done with thinning shears, a razor, or point cutting and should not be overused.
- Hair porosity
The ability of hair to absorb and hold moisture, rated low, normal, or high. High porosity hair takes in moisture quickly but loses it fast and needs gentle conditioning.
- Relaxer
- Related: Neutralizer
A chemical product with a high pH that straightens curly or wavy hair by breaking bonds in the hair. It requires careful timing, patch testing, and a neutralizer to stop the process.
- Neutralizer
- Related: Relaxer
A low-pH shampoo used after a relaxer to stop the chemical action and help restore the hair's normal pH. It must be used completely or the hair can continue to break.
