A comb with product residue, scissors passed from one client to another, or improperly managed blades can ruin a professional experience in minutes. Knowing how to disinfect hairdressing tools is not just a matter of order: it is part of the service, the safety, and the image a salon projects. At home, applying the same criteria helps take care of the scalp and extend the lifespan of each tool.
The key lies in not confusing three distinct processes. Cleaning removes hair, dust, grease, and visible residue. Disinfecting reduces microorganisms on non-porous surfaces and utensils using a suitable product. Sterilizing is a more demanding process, reserved for specific contexts and equipment. For a standard hairdressing routine, rigorous cleaning followed by proper disinfection is the practical standard.
How to disinfect hairdressing tools step by step
Proper disinfection does not consist of spraying a product on the tools and putting them away immediately. Order matters because visible dirt can prevent the disinfectant from working effectively. Always work in a clean area with good ventilation, clearly separating used material from the prepped items.
1. Remove visible residue. Remove hair from combs, brushes, clips, scissors, and heads. For brushes, use a tail comb or a specific tool to extract accumulated hair from the base. If there is hairspray, wax, dye, or oils, do not proceed directly to the disinfectant.
2. Wash when the material allows it. Non-electrical and water-resistant utensils should be washed with warm water and detergent or professional cleaner. Scrub joints, comb teeth, and surfaces where residue adheres. Afterwards, rinse and dry before disinfecting.
3. Apply the compatible disinfectant. Use a product formulated for hairdressing tools or a disinfectant suitable for non-porous surfaces, following the manufacturer's exact instructions for dilution, application method, and contact time. Some utensils are submerged, while others must be treated with a spray or disinfectant wipe.
4. Respect the action time and store correctly. The product needs to remain moist for the indicated time to act. Afterwards, let it air dry or dry with a clean towel if the label specifies so. Store the disinfected tools in a clean, closed, and dry container; never mix them with used material.
This protocol must be repeated between clients when the tool has been in contact with the hair or scalp. For home use, the frequency depends on how many people share the utensils, the use of styling products, and whether there is any sensitivity or condition on the scalp.
Which tools can be submerged and which cannot
Not all tools tolerate the same treatment. Resistant plastic combs, metal clips, scissors, hairpins, and some detachable heads can usually withstand washing and disinfection, provided the manufacturer does not indicate otherwise. Even so, scissors require additional attention: prolonged exposure to moisture or unsuitable products can promote corrosion and affect the screw or the blade edge.
After disinfecting professional scissors, dry them completely and apply a small amount of specific oil to the pivot point if it is part of their regular maintenance. This protects their precision without compromising hygiene.
Brushes deserve more careful treatment. Models with plastic bodies and synthetic bristles are easier to wash. However, brushes with cushions, wooden handles, natural bristles, or porous parts cannot always be submerged without deteriorating. Remove hair, clean accessible areas with a compatible product, and avoid soaking parts that retain moisture. When a brush is cracked, has a damaged cushion, or cannot be fully cleaned, replacing it is usually the most professional decision.
Hair dryers, flat irons, clippers, and curling irons
Electrical tools are never submerged. Before cleaning them, unplug them and wait until they are cool. Remove hair and dust from grilles, filters, and joints with a soft brush. Then, clean the exterior with a wipe or cloth barely dampened with a product compatible with the material, avoiding ports, switches, heating plates, and internal areas.
For clippers, remove the head if the model allows and eliminate trapped hair. Disinfect the blades with the product recommended for professional machinery and lubricate them afterwards if the manufacturer indicates so. A clean machine cuts better, heats up less, and reduces the risk of dragging residue between services.
Contact time is as important as the product
One of the most common mistakes is removing the disinfectant before the required time. A spray applied and dried immediately may leave the tool looking good, but it does not guarantee that the process indicated for that product has been completed.
Always read the label. It specifies if the product requires immersion, spraying, or application with a wipe, how long it must remain on the surface, and if it needs subsequent rinsing. It also clarifies which materials it can be used on. Mixing products or improvising concentrations does not improve the result and can damage plastic, metal, rubber, and coatings.
Alcohol can be useful on some small, non-porous surfaces, but it does not automatically replace a full protocol, nor is it suitable for all materials. Similarly, UV light cabinets can serve as supplementary storage for certain equipment, but they do not replace prior cleaning or chemical disinfection when the latter is necessary.
Professional organization: avoid cross-contamination
A good protocol depends as much on the product as on the organization of the workstation. Keep two separate containers or zones: one for tools awaiting cleaning and another for clean, disinfected utensils. This separation prevents a freshly treated clip from ending up next to a used comb by mistake.
Capes, towels, and textiles require a separate circuit. Shaking them out or reusing them without washing is not an acceptable alternative. They must be collected after each service and washed with the appropriate method before being used again. Support surfaces, chairs, shampoo stations, and carts also need frequent cleaning and disinfection, especially at direct contact points.
For a salon with a fast pace, it helps to create an opening, between-service, and closing routine. At the start of the day, prepped tools are checked; between clients, used utensils are processed; at the end, equipment, surfaces, filters, and storage areas are cleaned. This system reduces oversights and makes it easier for the whole team to work with the same criteria.
If there are cuts, irritation, or blood present
In the event of an accidental cut, stop the service and use disposable gloves. Immediately remove any tool that has come into contact with blood from use and process it according to local regulations and the disinfectant product's instructions. Single-use items, such as certain blades, files, or guards, must be disposed of safely and not reused.
If a client shows intense irritation, visible lesions, or signs of a possible scalp infection, it is advisable not to perform a service that could aggravate the area. Prudence protects the client, the professional, and the rest of the people served.
Errors that reduce the protocol's effectiveness
The first is disinfecting over hair and cosmetic residue. The second is using dirty containers or not renewing the disinfectant solution according to its instructions. It is also common to store damp tools, a practice that encourages bad odors, deterioration, and oxidation.
Another error is thinking that all material can be treated the same. A comb, scissors, a makeup brush, and a flat iron have different compositions and needs. Choosing compatible professional products, along with quality tools designed for continuous use, facilitates constant hygiene without accelerating wear and tear.
At LorenzoMirasierra, professional beauty is understood as a visible result, but also as a method. A clean, well-maintained tool ready for the next use conveys precision even before starting the service. Making disinfection a habit does not add unnecessary work: it protects your material, reinforces trust, and elevates every detail of your routine.
