A colourless liquid used to clean glue off hair lace and is an ingredient in many nail polish removers. It gives off unpleasant fumes and, therefore, it should only be used in well ventilated areas. It is also flammable, so it must be stored and used away from heat and direct sunlight.
A chemical product that is added to hair bleach to speed up the action of the bleach without unnecessarily damaging the hair. Also referred to as booster, bleach boosters or bleach accelerators.
Active ingredient is the generic term for a substance in a cosmetic that is biologically active. That is, it performs a specific function of benefit upon use. The rest of the ingredients in a product that simply act as a carrier for the active ingredient(s) are called inactive ingredients. In some countries, listing an active ingredient on a cosmetic has to adhere to strict guidelines. For example, in the USA, it must adhere to specific regulations mandated by the FDA.
Stands for α-Hydroxy acids, or alpha hydroxy acids. It is used in cosmetics products that claim to reduce wrinkles or the signs of ageing. It also claims to improve the overall look and feel of the skin. For an AHA to be useful, it has to penetrate the skin where it can act on the living cells. AHAs can be synthetically produced or they occur naturally. Many AHAs used in cosmetics come from food products, for example, glycolic acid from sugar cane, citric acid from citrus fruits and lactic acid from milk.
A technique used to apply a variety of liquid makeup products using an air compressor and an airbrush. The compressor pushes the liquid makeup product through the airbrush’s nozzle to create a fine mist of tiny droplets, which settle on the skin. It can be used for a wide range of things, from applying foundation to creating special effects.
The term for natural and synthetic ingredients that are used to help prevent free radical and environmental damage to our skin. Ingredients include vitamins E and C, grape seed extract, coenzyme Q10, and green tea. Understanding the benefits of antioxidants against the damage caused by free radicals is important. Subsequently, there is a huge amount of research conducted worldwide into antioxidants.
A hairpiece that is worn, as the name suggests, on the back half of the head. It uses the wearer’s own hair at the front to dress into the back fall. Back falls are good for situations where a front hairline on a wig would be visible. A back fall (sometimes just known as a “fall”) adds volume, texture or colour. The front of the back fall fits to the head on the very top of the crown area, in line with just behind the ears, and goes down to the nape.
The front hair that is cut to hang over the forehead. Also called the fringe.
The brand name of a product used in salons to disinfect hairdressing tools such as combs, rollers and scissors.
A hair setting technique where a small section of hair is curled up into an open, barrel-shaped roll and secured/pinned onto its section base.

BB stands for blemish balm or beauty balm and is a cream makeup product. It is promoted as an all-in-one facial product to replace serum, moisturiser, primer, foundation and sunblock (if it has an SPF). This means it can be worn alone as a tinted moisturiser or as foundation. It was originally formulated in the 1960s by German dermatologist Dr Christine Schrammek to protect patients’ skin after surgery. Subsequently, BB cream became a commercial product, particularly popular in Korea and other East Asian markets. Nowadays, BB cream is popular pretty much everywhere.
A block is a head- or chin-shaped item used in wig making and wig dressing. There are two different types: malleable blocks, which are made from cork-filled canvas and used to wash, set and dress postiche, and solid wooden blocks, used in wig making. Both types of block come in two different shapes: head-shaped (used for wigs) or chin-shaped (for facial hair) and is known as a chin block.
Malleable wig blocks come in even sizes from 50–60 (roughly, 50 = child; 52-56 = women; 56-60 = men). The size is often stamped on the base of the block. The pointed part of the base is generally the back, but some blocks can warp over time, so check the shape of the block to see the best way to attach the wig. The cork-filled canvas is not waterproof and, as water can distort the shape, blocks must be covered with plastic (like Clingfilm). This is then partially covered with a piece of white cloth which helps show the hair lace better and prevents the wig slipping (you should not pin a wig onto Clingfilm only as it slips).
A makeup product or technique designed specifically to cover skin pigmentation problems like vitiligo, scarring and birthmarks. Camouflage makeup products are highly pigmented, so it covers well and only a small amount of product is needed. When set with powder, many products are water, heat, sweat and rub resistant. Good brands include Dermacover, Dermablend, Veil and Supercover. Camouflage technique requires good colour theory and an eye for skin tones.
A hairstyle that involves a smooth, twisted, plaited or knotted roll of hair at the back of the head, especially the nape. Often used for evening wear and weddings, as well as for everyday. A flexible style, it can be structured and smooth, or the hair left soft, loose and informal.
A cluster is a hair piece with a solid round base that is used to add bulk to a hairstyle, allowing for more elaborate styling, or to add a detail like a pony tail. The cluster starts life as a weft and is stitched into a circular structure for easy of use. Often has little wig clips sewn in to help attach it to the wearer’s head.

The hard outer layer of the hair constructed of dead overlapping scales, which form a protective layer. Healthy cuticles also impart sheen to the hair. Cuticles can be damaged with heat, over brushing and chemicals (e.g. perms, colouring) causing splits, split ends or bloating due to over processing.
This refers to a soft sheen created on the skin by some cosmetics, in particular foundation. It creates that fresh-faced look often used in photography.
A large circular adapter that you put on the end of your hair dryer. The small holes in the diffuser spread out the air flow from your hair dryer, so you don’t get the full force of the air, creating a gentler drying process. When used on a cooler heat setting, it is good for curly/wavy hair to help dry without frizz.
A test carried out by a hairdresser to check the strength and condition of the hair’s cortex. Hair is elastic to a point, especially when wet, but will spring back if healthy. Carrying out an elasticity test tells us how healthy the hair is. Take one strand of hair and hold each end firmly between the thumb and forefinger of each hand and gently pull. If the hair stretches more than half of its original length then it is over elastic and may snap or break during chemical processing. If it snaps easily, then it has poor elasticity.
The outer layers of the skin which forms a protective barrier over the body. Also controls temperature, evaporation, sensitivity and absorption.
A process of cleaning the face/skin using a gentle abrasive product that removes the loose dead skin cells on the surface of the skin, leaving the newer skin cells underneath. An exfoliator that uses round beads (like jojoba) is good for faces and the décolleté as it doesn’t scratch your skin.
A hairdressing technique that creates a series of S-shaped waves in the hair. Popular for the short haircuts of the 1920s and ’30s. Also called water waves.

Hot rollers, tongs or Marcel tongs can also be used to create the waves.
A makeup product that is applied to the skin using a sponge, brush, airbrush or fingers, primarily to smooth out skin tone, cover minor blemishes and create an even base for other makeup products to go on. Many different foundation types include cream, liquid and powder formulations.
A term used to describe atoms, molecules or ions with unpaired electrons and free radicals play an important role in a number of biological processes. However, the same free radicals can participate in unwanted side reactions, causing cell damage which contributes to illness, cancers, and ageing. Antioxidants are a major way to slow the impact of free radicals, hence the wide range of cosmetics containing antioxidants such as vitamin C to help combat ageing and environmental skin damage from free radicals.
An elegant up-do hairstyle for longer hair that involves twisting the hair at the back into a sleek vertical roll.
Galloon is a thin nylon or silk ribbon used to secure the front hair lace of a wig to the wig block. It reinforces the wig lace when blocked and prevents it from tearing. It comes in different widths (about 5-12mm) and is pinned over the hair lace to the block with small dressmakers pins called short whites. Galloon is also used to add strength to a foundations e.g. at the nape of a wig. It comes in a long length, so it can be cut as required, and is available in the basic hair colours (black, browns, grey, blonde).

A contouring technique used to draw subtle attention to a facial feature by using a lighter colour. For example, using a slightly lighter foundation on cheek bones to create width. Likewise, using a lighter eye shadow under the eye brows to create lift. Highlighting has the opposite effect of shading.
A term that refers to the darkening of an area of skin due to the abnormal excessive production of melanin (the pigment that contributes to skin colour).
A test carried out on hair before a chemical service (tinting, bleaching, perming) takes place to see if the hair contains anything that will react to the service, or prevent it from working properly. A small strand of hair is taken and immersed in the solution to be used for ten minutes. No reaction means the service can go ahead.
