Cleaning and disinfecting tools and equipment form an essential part of the post-service procedure in hair coloring. In Kenyan cosmetology salons and spas, maintaining impeccable hygiene standards protects clients from infections and ensures the longevity of expensive tools. Proper cleaning and disinfection practices also uphold professional reputation and comply with regulatory requirements from bodies such as the Kenya Bureau of Standards (KEBS) and the Ministry of Health. This chapter focuses on the systematic procedures for cleaning and disinfecting hair coloring tools and equipment to promote safe and effective salon operations.

3.1 Cleaning and Disinfecting of Tools and Equipment Procedures

Cleaning and disinfecting are critical processes that prevent cross-contamination between clients and maintain a hygienic working environment in hair salons. Because salons serve many clients every day, following these procedures minimises the risk of transmitting fungal, bacterial, and viral infections. Proper cleaning removes visible debris and chemical residues, while disinfection destroys most microorganisms. Together, these steps ensure tools such as brushes, combs, applicators, and bowls are safe for reuse.

Work station clearing

Work station clearing is the first step after a hair colouring service. It means removing used items, waste, and spills from the styling area so that nothing contaminated stays near the next client. Example: in a busy salon, the stylist who clears the trolley, chair, and basin area straight after rinsing a client prevents dye stains from drying on surfaces and stops used tools from being mixed up with clean ones.

1. Switch off electrical equipment: Turn off and unplug dryers, steamers, and heat lamps before touching the area, so that no one is exposed to electric shock while surfaces are being wiped.
2. Put on protective gloves: Wear gloves before handling used tools, towels, or colour residues, because these may carry dye chemicals, hair, skin cells, and microorganisms.
3. Dispose of single-use items: Place used gloves, neck strips, cotton wool, foil, and tissue in a lined, covered bin. These items must never be reused or left on the work surface.
4. Collect used tools in one container: Put combs, brushes, bowls, and applicator bottles into a labelled "dirty" tray or basin, kept separate from clean tools, so they can be taken to the cleaning area together.
5. Remove soiled linen: Place used towels and capes in a laundry bag or bucket with a lid. Do not drop them on the floor or on a chair that the next client will use.
6. Wipe down work surfaces: Clean the trolley, counter, and chair arms with detergent and a clean cloth to remove colour splashes and hair, and disinfect them afterwards.
7. Sweep up hair and clean spills: Remove cut or loose hair from the floor and mop up colour spills immediately, since they stain and can cause slips.
8. Remove gloves and wash hands: Take off gloves correctly, discard them, and wash hands with soap and clean water before setting up for the next client.

Cleaning

Cleaning involves the physical removal of dirt, hair, chemical residues, and organic matter from tools and surfaces. This is usually done using soap or detergent and water to reduce the number of microorganisms present. The process improves the effectiveness of subsequent disinfection by eliminating the layers that protect microbes. Example: a hotel spa salon that scrubs every colour bowl with warm soapy water before disinfecting finds that stains and oily films no longer shield germs from the disinfectant.

• Removal of visible debris: Cleaning eliminates hair strands, colour stains, and oils that accumulate on tools during hair colouring.
• Use of appropriate cleaning agents: Mild detergents or enzymatic cleaners break down organic material without damaging delicate tools.
• Mechanical action: Scrubbing or brushing enhances removal of residues from hard-to-reach crevices in combs and brushes.
• Rinsing with clean water: Thorough rinsing ensures no cleaning agent residues remain, which could interfere with disinfection or harm clients.
• Dedicated cleaning equipment: Use brushes and cloths kept only for cleaning tools, and wash and dry them after use so that they do not spread dirt to the next batch.

Procedure for cleaning tools:

1. Wear gloves: Protect the hands from chemicals and contaminants during cleaning.
2. Remove excess hair and product: Rinse tools under running water or wipe them with tissue to take off loose residues.
3. Prepare a cleaning solution: Mix warm water with a mild detergent or enzymatic cleaner suitable for salon tools.
4. Soak the tools: Leave brushes, combs, and bowls in the cleaning solution for at least 10 minutes to loosen dirt and colour stains.
5. Scrub thoroughly: Use a brush or cloth to remove all visible debris, paying attention to crevices and bristles.
6. Rinse under running clean water: Remove soap residues completely.
7. Dry properly: Use a clean towel or air dry, as moisture can dilute the disinfectant and reduce its efficacy.

Disinfecting

Disinfection is the chemical or physical process that kills or inactivates most pathogenic microorganisms on cleaned surfaces. While it does not remove dirt, it significantly reduces infection risk. Example: a college training salon immerses cleaned combs in a freshly prepared disinfectant for the full contact time before each practical lesson, so that students can share tools safely.

• Use of approved disinfectants: Products such as a quaternary ammonium salon disinfectant, 70% isopropyl alcohol, or sodium hypochlorite solution are used for salon tools, always according to the label.
• Contact time adherence: Disinfectants require specific exposure times, often 10 to 15 minutes, to be effective against bacteria, fungi, and viruses.
• Surface compatibility: Selection of disinfectants must consider tool material to avoid corrosion or damage, especially for metal or plastic items.
• Scope of microbial kill: Disinfection targets most pathogens but does not guarantee sterilisation, which is reserved for surgical instruments.
• Safe handling: Correct dilution, labelling, and use of disinfectants protect salon workers and clients from chemical hazards.

Procedure for disinfecting tools:

1. Check that tools are clean and dry: Disinfectant cannot work on surfaces that still carry dye, hair, or soap film, so return any dirty tool to the cleaning stage.
2. Wear protective equipment: Put on gloves and an apron, and work in a ventilated area to avoid skin contact and inhaling fumes.
3. Prepare the disinfectant solution: Follow the manufacturer's instructions to get the correct concentration. Never mix different disinfectants or add bleach to other chemicals.
4. Immerse the tools fully: Submerge them in the disinfectant, or apply a disinfectant spray, so that all surfaces, including handles and teeth, are covered.
5. Allow the disinfectant to act: Leave the tools for the prescribed contact time, typically 10 to 15 minutes, and note the start time so the period is not cut short.
6. Remove the tools safely: Use gloved hands or clean tongs, and rinse if required by the disinfectant type.
7. Dry completely: Use a clean towel or air dry before the tools go to storage.

Storage

Storage keeps cleaned and disinfected tools in a condition fit for the next client. Tools that are returned to a damp drawer, an open tray, or a dusty counter can be recontaminated within minutes, which cancels the work already done. Example: a salon keeps disinfected combs and brushes in a covered, labelled plastic container on a high shelf, separate from the tray of used tools, so any stylist can see at a glance which tools are ready.

• Clean, dry, covered containers: Store cleaned and disinfected tools in a clean, dry, and covered container to prevent recontamination.
• Separation of clean and used tools: Keep clearly labelled containers for "clean" and "used" tools, and never place them next to each other.
• Complete drying before storage: Moisture allows microbes and mould to grow and can rust metal parts, so tools must be dry before being closed in a container.
• Clean storage surfaces: Wipe drawers, trays, and shelves regularly and line them with clean material so that tools do not touch contaminated surfaces.
• Safe storage of chemicals: Keep disinfectants and colour products in closed, labelled containers, away from children and food areas, and away from the tool storage.
• Regular checking: Inspect stored tools for dust, damage, or dampness, and return any doubtful item to the cleaning and disinfecting stages.

Cleaning and disinfecting specific tools after hair colouring

Each tool used in colouring has its own material and shape, so the cleaning and disinfecting method must suit it to keep it hygienic and in working order.

• Brushes and combs: These collect dye, oils, and scalp debris. Synthetic-bristle brushes are soaked in detergent solution, scrubbed, rinsed, and then disinfected with a quaternary ammonium salon disinfectant. Wooden combs swell in water, so they are cleaned quickly, wiped, and disinfected with an alcohol-based spray.
• Applicator bottles and bowls: Empty and rinse plastic or glass bowls and bottles immediately after use, before pigment dries. Wash with warm soapy water, then disinfect with sodium hypochlorite diluted to 0.5% for 10 minutes to prevent chemical build-up and microbial growth.
• Sectioning clips and pins: Wash and dry metal clips thoroughly before disinfecting, because leftover moisture and dye encourage rust and staining.
• Capes: Launder reusable capes in hot water with detergent after each client. Where laundering is not immediate, a spray disinfectant between clients reduces infection risk.
• Towels and reusable neck strips: Change towels for each client and wash them in hot water with detergent. Neck strips that are not single-use must be laundered straight after use.

Chemical safety and good practice during cleaning and disinfecting

Safe working habits protect staff and clients from chemical hazards, and consistent routines keep results reliable from one shift to the next.

• Measure, do not guess: Use a marked measuring jug to prepare solutions, so that the concentration is neither too weak to work nor strong enough to damage tools or skin.
• Label solutions: Write the product name, dilution, and time of preparation on the container so that every staff member knows what it is and when it must be replaced.
• Replace solutions daily: Prepare fresh disinfectant each day, or sooner if it is visibly soiled, because used solution loses strength.
• Cover cuts: Protect cuts or broken skin on the hands with a waterproof dressing under gloves before handling chemicals.
• Respond to splashes: Rinse chemical splashes on skin or in the eyes immediately with plenty of clean running water and seek medical help if irritation continues.
• Keep a cleaning and disinfection log: Record what was cleaned, when, and by whom, so that procedures are consistent across shifts.
• Train all staff: Give regular training on hygiene routines and chemical handling so that everyone follows the same standard.
• Allow time between clients: Schedule appointments with enough time for thorough clearing, cleaning, and disinfecting between services.
