Maharashtra HSC NSQF Beauty Therapist key terms

The invasion of body tissue by disease-causing microorganisms such as bacteria, fungi or viruses, which multiply and produce harmful effects. In a salon it spreads through unclean tools, hands, linen and surfaces.

The transfer of microorganisms from one person, tool or surface to another, often by indirect contact such as a shared towel, unwashed hands or a reused implement. It is the main route of salon-acquired infection.

A process that destroys all microorganisms, including bacterial spores, on an object. It is required for items that may contact broken skin or blood, and is achieved by autoclave, dry heat or approved chemical methods.

The use of a chemical agent to reduce the number of pathogenic microorganisms on tools and surfaces, but not necessarily bacterial spores. It is the standard level of protection for most reusable salon implements after cleaning.

The routine cleaning and chemical treatment of surfaces, floors, linen and hands to lower microbe counts to a safe public-health level. It is a lower level of protection than disinfection and is done frequently throughout the working day.

A product or implement designed to be used on one client only and then discarded, such as disposable spatulas, nail files, gloves, razors and wax strips. Reusing it creates a direct cross-contamination risk.

Material Safety Data Sheet: a document supplied with a chemical product that lists its hazards, safe handling, first-aid measures and storage requirements. Salon staff must keep these sheets accessible for every professional product used.

A small controlled application of a product, usually on the inner forearm or behind the ear, to check for an allergic reaction before full treatment. It is essential for hair colour, bleach and some skin products.

Any condition, medication or circumstance that makes a treatment unsafe or inadvisable for a client. Examples include broken skin, active infection, recent cosmetic surgery or use of blood thinners. Identifying it protects both client and therapist.

A confidential written or digital form that records a client's contact details, medical history, allergies, patch-test results, products used and treatment outcomes. It supports continuity of care and provides legal evidence of professional practice.

A client's voluntary agreement to a treatment after being told its purpose, procedure, expected results, risks and alternatives. It must be obtained before service begins and documented in the client's record.

The outermost, avascular layer of the skin, composed of keratinocytes that continually renew. Its outer stratum corneum acts as the main barrier against water loss and infection. Cosmetic products and peels work mainly at this level.

The middle layer of skin beneath the epidermis, containing collagen, elastin, blood vessels, nerves, hair follicles and glands. It provides strength, elasticity and nourishment, and its changes with age produce wrinkles and sagging.

The outermost layer of the epidermis, made of flattened, dead keratin-filled cells held together by lipids. It limits water loss and blocks entry of microbes. Exfoliation and moisturising mainly target this layer.

A tough structural protein that forms the main substance of skin, hair and nails. Its arrangement and condition determine strength, texture and shine, and its damage through heat or chemicals causes dryness and breakage.

A fibrous protein in the dermis that gives skin its strength and structural support. Production declines with age and sun exposure, contributing to fine lines and loss of firmness. It is a key target of anti-ageing products.

A resilient protein in the dermis that allows skin to stretch and spring back into shape. Its breakdown from ageing and UV damage leads to sagging and loss of elasticity, which massage and skincare aim to slow.

The visible part of a hair above the scalp, made of keratin in three layers: cuticle, cortex and medulla. Its condition determines shine and manageability, and chemical or heat treatments act mainly on the cuticle and cortex.

The outermost, overlapping scale layer of the hair shaft that protects the cortex. When it lies flat, hair looks smooth and shiny; when raised by chemicals, heat or rough handling, hair becomes dull, porous and prone to breakage.

The repeating phases of hair growth: anagen (active growth), catagen (transition) and telogen (rest and shedding). Understanding it explains why waxing needs a minimum hair length and why some hair loss is normal.

The active growth phase of the hair cycle, lasting months to years, during which the follicle produces a new hair. Hair is most firmly rooted then, so waxing during this phase gives the best long-term reduction in regrowth.

The hard, translucent keratin structure covering the nail bed, protecting the sensitive fingertip and aiding fine manipulation. Its appearance reflects health, and its condition is central to manicure and pedicure assessment.

The pinkish tissue beneath the nail plate, rich in blood vessels, which nourishes the nail and gives the plate its colour. Injury or disease here can permanently alter nail growth and appearance.

The thin band of dead skin at the base of the nail plate where it meets the skin, sealing the gap against infection. It should be softened and gently pushed back, never cut, during a professional manicure.

A classification of skin as normal, dry, oily, combination or sensitive, based on oil production, moisture and pore appearance. Correct identification guides product selection and treatment planning during consultation.

A temporary or persistent abnormality of the skin, such as acne, dehydration, pigmentation, rosacea or sensitivity, that is distinct from the client's basic skin type. Conditions may require referral rather than direct treatment.

A six-point classification of skin tone based on response to ultraviolet light, from very fair to deeply pigmented. It guides safe selection of wax temperatures, laser settings, exfoliation strength and sun-protection advice.

A structured pre-treatment conversation and visual analysis to establish the client's needs, expectations, medical history, allergies and contraindications. It ends with an agreed treatment plan and documented consent, forming the basis of safe practice.

The removal of dirt, sebum, sweat and make-up from the skin using a suitable cleanser and gentle technique. It is the first and essential step of every facial, preparing skin for analysis and further products.

The removal of dead cells from the skin's surface by mechanical scrubs or chemical agents such as alpha-hydroxy acids. It brightens skin and improves product absorption, but must be avoided on broken or irritated skin.

The named manual strokes used in facial and body treatments, such as effleurage, petrissage, tapotement and friction. Each has a specific purpose, direction and pressure, and correct sequence improves circulation and relaxation.

A cosmetic base in which oil and water are mixed and held together by an emulsifier, forming a cream or lotion. Most moisturisers are emulsions, and their oil-to-water ratio determines whether they suit dry or oily skin.

An ingredient such as glycerin or hyaluronic acid that attracts and holds water in the skin, improving hydration. It works best when combined with an occlusive agent that prevents the water from evaporating away.

An ingredient that forms a barrier on the skin surface to reduce water loss, such as petrolatum, lanolin or silicone. Occlusives are useful for very dry skin but may feel heavy or aggravate oily, acne-prone skin.

A hair-removal technique in which a twisted cotton thread is rolled over the skin to trap and pull hairs from the follicle. It is precise, suitable for eyebrows and the face, and requires firm, even tension.

A hair-removal method that applies warm or hot wax to the skin so it grips the hairs, then strips them out against the direction of growth. Correct temperature and skin tension prevent burns and bruising.

The angle in which hair emerges from the follicle and lies on the skin. Wax is applied with the growth and removed against it, while threading and shaving follow their own rules, to minimise breakage and discomfort.

A cosmetic treatment of the hands and nails including shaping, cuticle care, exfoliation, massage and polish. It improves appearance and hygiene, and allows the therapist to observe nail and skin abnormalities for referral.

A treatment of the feet and toenails involving soaking, exfoliation, callus removal, nail shaping, massage and polish. It requires extra attention to infection control and to clients with diabetes or circulatory problems.

Shaping and drying hair with a hand-held dryer and brush using controlled heat, airflow and tension. Direction and nozzle choice determine volume, smoothness and the finished style, while excessive heat causes cuticle damage.

Dividing the hair into clean, controlled portions using clips and partings before cutting, colouring or styling. It ensures even results, prevents missed areas and allows systematic working from a stable base line.

Selecting a base product whose undertone and depth blend seamlessly with the client's natural skin tone at the jawline. Correct matching in natural light avoids a visible line and creates a natural, even finish.

The use of complementary colours in make-up to neutralise unwanted tones on the skin, such as green for redness or peach for dark circles. It is applied in thin layers beneath foundation for a balanced result.

The moral principles guiding a beauty therapist's conduct, including honesty, confidentiality, respect for clients, working within one's competence and refusing unsafe or inappropriate treatments. It protects clients and upholds the reputation of the profession.

The boundaries of the treatments and advice a qualified beauty therapist is trained and legally permitted to provide. Working outside it, such as diagnosing skin disease, risks harm and may breach regulations.

The planned progression of roles and qualifications available in the beauty industry, from assistant or junior therapist through senior therapist, salon manager, educator or business owner. It helps candidates set realistic goals.

The process of identifying an opportunity, planning and launching a beauty business, and managing its finances, marketing, staff and risks. It requires commercial skill alongside technical competence and legal compliance.

The systematic tracking of stock levels, usage, expiry dates and reorder points for products and consumables. Good control prevents shortages, reduces waste and ties up less capital in unused stock.

First In, First Out: a stock rotation rule in which older products are used before newer ones. It reduces waste from expired cosmetics and ensures that opened retail stock reaches clients while still effective.

Recommending an upgraded or additional service or product that genuinely meets the client's identified needs. Done ethically, it increases revenue and client satisfaction; done pushily, it damages trust.
