Texas Class A Barber key terms

The angle at which hair is held away from the head before cutting; it controls the length relationship between sections and determines whether a cut is blunt, graduated, or layered.

The first section of hair cut in a service; it sets the reference length that later sections follow so the finished shape stays balanced and consistent.

Dividing the hair into clean, manageable subsections with clips or partings so each area can be cut, colored, or styled evenly and predictably.

A cutting technique where hair lengths build up in stacked layers, usually longer at the top and shorter underneath; elevation stays low to medium.

A barbering technique where clippers run along a comb held against the head to remove bulk and blend shorter areas, often used for tapers and fades.

A gradual shortening of hair at the sides and back, usually from the nape or sideburn upward, leaving enough length for a soft, blended finish.

A very short haircut where the sides and back blend from skin or near-skin at the bottom to longer hair at the top, with no visible lines.

A texturizing method in which scissor tips make small vertical snips into the ends of a section, softening weight and creating movement without shortening the overall shape much.

The natural direction in which a person's hair grows from the scalp, including cowlicks and swirls; it affects how hair lies and how a cut should be directed.

A contagious fungal infection of the scalp and hair shafts that causes scaly patches and broken hairs; barbers must not service it and should refer the client to a physician.

A moist, lubricating foam applied to soften the beard and protect skin during shaving, allowing the razor to glide and reducing friction, nicks, and irritation.

The tilt of the razor blade against the skin during a shave; a shallow angle reduces scraping and cuts while still removing hair efficiently.

Shaving in the direction the beard hair grows; this is the gentlest pass and is recommended first to reduce irritation, especially for sensitive skin.

Grinding a straight razor's edge on a hone to restore its shape and sharpness before stropping; it removes metal and sets the cutting edge.

A chemical service that straightens curly or tightly coiled hair by breaking its protein bonds; it requires careful timing, protection, and thorough rinsing.

The active reducing agent in most permanent wave lotions; it breaks disulfide bonds in the hair so the hair can be reshaped around a rod.

A strong alkaline straightener, often called lye relaxer, that breaks hair bonds quickly; it requires scalp protection and careful monitoring to avoid burns and overprocessing.

A chemical applied after a permanent wave or relaxer to stop the reduction process and rebuild disulfide bonds, locking the new shape into the hair.

A small skin test done before a color or chemical service to check for an allergic reaction; any redness, swelling, or itching means the product should not be used.

A test on a small sample of the client's hair before a chemical service to judge processing time, product strength, and possible damage or unwanted color result.

How the hair is held relative to the scalp during chemical processing; it affects lift, tension, and how much relaxer or wave reaches the hair.
